Servicing 2020
Since the business was established in 1956, the workshop has always been right at the heart of Geoffrey Butler Cycles!


Our two long term expert mechanics, Pete and Ben can count over 50 years of combined experience in the trade!


They are skilled to repair any kind of bike imaginable...

...Road Racing, Time trial, Winter Bikes, Mountain Bikes, DH, XC etc, City Bikes, Dutch Style bikes, folding bikes (Actually Bromptons are one of our big specialities!) and even tandems and recumbents!


We’ve seen everything come through the GB cycles workshop and we have the skills, and pride to get them all working at their absolute best.

Pete and Ben are backed up by an incredibly well equipped workshop with a range of tools from vintage frame working up to current kit for suspension, hydraulics, dropper seat-posts and electronic diagnostics.

Campagnolo Spoken Here! Word gets around but if you haven't had your ear to the grapevine you need to know that we are one of the best out there for all things campag. You would probably have to travel to Vicenza, Italy to find a better place to have your Campagnolo equipment looked after!

Of course, Shimano and SRAM components are the other 2 of the big 3 current industry leading brands. Naturally we have all experience and equipment to look after them all, including hydraulic disc brakes, internal-gear hub systems, and the electronic wired and wireless shifting systems.

Electric Bikes. We are fully trained and licenced by Bosch to service, fault find and firmware update all current models of Bosch power systems.We can apply this to units fitted to all major brand bikes such as Trek, Scott, Cube, Haibike and more. We can also carry out certain repairs to non Bosch powered ebikes, its usually best to discuss this with us.

We like a challenge, got a creak? Want a custom bike built from scratch? Bring it on! we're so confident we challenge you to bring something that we couldn't turn our hand to!



Find below our "set menu' of service and repair jobs starting with our infamous Platinum Service!

 

Platinum Service 
 
£180 plus parts*

Total Strip down, Clean, refurbish and Re-Build; The Platinum service is our most prestigious workshop job.

Whether it’s an essential commute rig, a thoroughbred race machine or your prized Sunday bike; with great care and skill we endeavour to give your bike its mojo back! The Platinum service essentially includes nearly every service and cleaning element we can perform wrapped into one offering a total transformation to the bike and making it extremely good value for money.

So what do we do?

Well, when you arrive with the bike we'll have a quick chat with you to discuss the job in hand.
This is the time to make us aware of any particular issues we need to be aware of or a change you would like made such as riding position, gear ratios or an upgrade maybe?
If you have a road bike with bar tape, you will need to choose or supply a replacement as we very rarely manage to remove and re-use the old tape.

Now you can tear yourself away from your bike. Leave it with us, its in safe hands!


On the day of your booking we will carefully strip the entire bike, every nut, bolt and washer as it were comes off. We have the correct tool for everything. Every single item is methodically laid out and inspected for wear or damage.

The frame, fork, rims and hubs are checked for wear or cracks, as is the drive-train looking for such things as stretched chain, worn sprocket teeth etc,

Brake pads are checked.

Once we have been over the condition of everything and discussed any issues with you we will start the operation.

The entire drive-train including chainrings, cranks, chain, cassette, derailleurs and brakes will be cleaned in our friendly but effective parts washer to remove all traces of oil, dirt and grime. Not only will they shine but more importantly they'll be rid of the muck and salt that cause wear and damage!

Wheels including their internal parts go through the same treatment.

The frame and fork is gently cleaned with suitable products and methods depending on the frame's finish and type of dirt.

All parts are rinsed, dried and re-laid out for assembly.
The headset is greased and re-fitted, new bearings fitted if needed* and the fork goes back in.
When the stem, top cap and handlebar clamps are re-fitted, contact surfaces are checked for corrosion, bolts are re-greased where required and tightened to recommended torque settings.

Drive-train. The bottom bracket is fitted, chainset and derailleurs are re-installed as well as brake calipers.
All pivot points in the brakes and derailleurs are lubed for smooth operation, salt protection and increased durability.

Quite often the chain and cassette will need to be replaced depending on wear, occasionally chain-rings too. We will always pick up on these and discuss our recommendations prior to replacement. If these parts are in perfect health, naturally we will thoroughly clean and re-use them.
Brake pads will be re-installed, new if required*.
Note: Hydraulic brake systems may require additional work (fluid leaks, correcting sluggish/biasing pistons etc), usually this work can be included in the Platinum service but if there is anything extra, we will discuss this with you.

All new cables are fitted* to bring out the best in the components.

The hubs will be thoroughly greased and re-assembled. Loose ball arrangements may require new balls and/or cones but originals are re-used if healthy. Cartridge bearings will be replaced where needed*. If the cartridge bearings are healthy, the seals will be lubed and axles adjusted for maximum weather resistance.

The wheels will be cleaned and inspected for wear or cracks. Spoke tensions will be checked and wheels will be trued and dished if required.

Tyres will be checked and inflated correctly. Replaced if required*.
The seat post will be re-fitted with the appropriate grease or carbon paste. The height will be set at the height that it was before removal. The clamp is then tightened to the recommended torque.

Once the bike is fully assembled, we will test and fine tune the entire bike making sure everything is spot on.
A quick road test is carried out to ensure everything behaves as it should under load and in a real world scenario. This also clarifies that there are no clicks or creaks or rattles present before signing off the job!

Gold Service
 
£140 plus parts*

Need a little extra TLC?

There are many occasions where the Platinum service is overkill so the Gold Service covers all mechanical aspects of the Silver Service but with a comprehensive valet included. And we don't just mean a quick hose down! With the combined price of a Silver Service and a Full Valet costing £160, you will be saving £20 when having a Gold!  

So.. before we carry out all the setup/adjustments and checks of the silver service we will do the following:

Thorough inspection:

Frame, fork and all components checked for damage or wear. If something needs repairing/replacing we will discuss this with you.

Cleaning Process:

Entire Drivetrain removed; this comprises of the chain, cassette, chainset, front and rear derailleurs, these will be thoroughly cleaned in our Ozzy Juice Parts washer. This will remove every unwanted particle on these vital components!
Note, unlike some shops, we never wash your jockey wheels in the parts washer, they are removed before hand and hand cleaned as the degreaser will ruin the bearings in them.

The Bottom bracket will be removed, threads or contact surfaces will be cleaned, greased and re-fitted. We do this now to stop water entering the frame during washing.

The seat post is removed, inside the frame is cleaned and suitable grease/grip paste applied. The post is cleaned and re-fitted. Same theory applies regarding water entering the frame.

The bike will then have a detailed wash with appropriate products and methods depending on the part or material.

As well as making it look good, its important to keep a bike clean, salt in particular is very damaging to the various alloys and steels on all bike and sand trapped in certain areas is abrasive.

Once everything is clean, rinsed and dried including the drive components, the bike is re-assembled.

Note: Occasionally the inner cables cannot be re-used as they fray at the fixing bolt so a new one will be required.

The chain will be re-lubed with a premium quality oil

PTFE spray applied to bolts and surfaces where required to protect.

If the bike has suspension units, the seals and upper legs treated with a specific suspension lubricant.

We will now carry on with all the tuning and adjustments as per the Silver Service.


Silver Service

£80
plus parts*

Our most popular service.

The aim of the Silver service is to ensure that your bike is performing as well as it possibly can, that no issues are causing premature wear to components and most importantly that the bike is safe and reliable. Here’s what we do:

Thorough inspection:

Frame, fork and all components checked for damage or wear. If something needs repairing/replacing we will discuss this with you.
 
Adjustments:

Front and rear brakes checked and adjusted.

Front and rear derailleurs adjusted and the mech hanger will be aligned if required. Pivot points will be lubed for smooth operation and protection against corrosion.

Headset checked and adjusted.

Seat post removed, cleaned and re-fitted with correct grease or grip paste.

Hubs checked for play and adjusted. (Cartridge bearings will need to be replaced if worn)

Pedals removed, threads greased and re-fitted.

Spoke tensions checked and wheels trued.

Tyres inflated correctly.

All bolts and fasteners checked and set to correct torque settings.

Once this is all carried out you will most definitely notice your bike will feel crisper and more accurate to ride, positive brakes and consistent gear shifting makes for a confident ride.

You can also rest assured that any underlying issues will have been found and corrected avoiding a bigger bill in the future!
 
For the silver service we would ask you to bring your bike in a relatively clean state. No cleaning is included in the cost and if any cleaning is required to carry out a certain aspect of the service, it may be charged accordingly.

Also, we're always fair here at Geoffrey Butlers. If you book your bike in for a Silver Service and the work required is minimal we will simply charge you the Bronze service charge.



Bronze Service

£40 plus parts
*

The bronze service is a handy quick check and tune.

Ideal for a newer bike or a bike with low use since its last service. You could think of this as a discounted Silver Service based on the fact that it wont take us as long.

Brakes checked and adjusted.

Gears checked and adjusted.

Cranks and pedals checked and correctly tightened.

Tyres checked and pumped up.

Headset checked and adjusted.

All important bolts checked and tightened.

A visual check of everything else is carried out.

If the level of work/time taken to bring the bike up to a acceptable standard takes longer than usual then upgrading to the Silver service will be required/charged.


How long will a service take?

We can turn around most Service and repair work in a 24 hour period, as long as any required parts are in stock. Should there be any reason for delay, we will notify you and do our best to minimise the wait.

Customers can bring their bikes in during normal shop hours and a pick date and time will be agreed at drop off.
We can be flexible, for example; if you need to bring a bike in on Saturday and collect it the following Saturday, no problem. Just discuss your needs with us.
 
We would usually ask you to collect your bike within a week of it being serviced or repaired just so that we don't end up with too many bikes to safely store.

If however there is no rush to get your bike back, this can actually be helpful to us as in particularly busy spells we can prioritize urgent jobs and book yours for a quieter time, just fill us in with dates etc. 


This sounds nasty but we reserve the right to charge for storage if bikes are not collected within a reasonable time**. Also bikes or parts left with us for more than 6 months without communication may be disposed of.
 


Other Services


If your bike doesn’t necessarily require one of our 3 set level services, we can carry out any individual job. Below are just a few popular jobs with guide prices but you name the job, we can do it.

 

  • 6-8 Week service.
    If you buy a bike from us, we will carry out a thorough checkover after you have covered a few “settling in” miles. There are elements to a bike that might need re-tweaking, gear cables can stretch for example. Other areas include spoke tensions, bolt torque settings, bearing pre-loads etc. We will cover all aspects for complete peace of mind and to ensure that everything will operate correctly giving a safe and longest possible. This is strictly for bikes purchased from us, proof of purchase will be required and if outside the 8 week term, labour charges may apply.  Gear Setup, £20.00 Check and adjust all gear settings. This charge includes inner cable replacement if a cable is purchased (does not include hanger alignment).
  • Brake Setup, £15.00 per brake
    Check and adjust front and rear brakes for safe and correct operation. This charge includes fitting new pads if purchased.
  • Fitting new bottom bracket, £20-30
      
         
  • Fitting a chain, £10.00
    The chain on your bike is the first part to wear, it stretches. As it wears past a certain point it will then wear out the teeth on your cassette and chainrings. If this is periodically checked and the chain replaced in time, you will greatly preserve the life of the other parts. Drop in any time and we can accurately determine the wear and whether it should be changed or not. Gear indexing charged at £15 extra if required.
  • Mech/Derailleur Hanger Alignment, £15.00
    The mech hanger is a crucial part that is often overlooked, it holds the rear mech directly in line with the rear wheel and sprockets. If you are having problematic shifting regardless of how hard you try to tune the rear mech, then it’s more than likely that the hanger is slightly bent. The only way to establish whether or not it’s correct is to remove the derailleur and attach a special tool in its place. This tool checks its position in relation to the wheel in infinite positions allowing perfect calibration. Warning! The rear mech often gets knocked and being made of alloy, the hanger bends easily, the result can be disastrous! The chain can drop down between the spokes and the cassette as it turns, the events that follow include broken spokes, the mech being dragged around striking and breaking breaks the frame, followed by the rider having a crash with the loss of control. The £15 is a small price to pay! Gear indexing will be charged at £15 extra afterwards if required.
  • Fitting a new headset, from £10.00
    This covers fitting most types of headset and into a frame. Steerer tube cutting and bung fitting are charged as extras.
  • Replacing headset, £20.00
    Removing an existing headset and fitting a new one.
  • Headset Service, £20.00
    Removing headset cleaning, and replacing bearings where needed.*
  • Fitting bar tape, £10.00
  • Fit Mudguards, From £15.00
  • Fit Pannier Rack, £10.00
  • Fit Computer, £10.00
    We will neatly fit the sensor/sensors and head unit, calibrate head unit including tyre size, units, date and time etc. Some wired or cadence systems may be extra. Free fitting for computers bought in store!
  • Light fitting, £5.00
    Free fitting for lights bought in store.
  • Stabilizer fitting, from £10.00
  • Fork Fitting, £40.00
    Upgrading your fork? Maybe this a part of a build up that you’re not sure about doing yourself? No problem, leave it to us. We have all the tools for cutting the steerer tube, fitting the crown race and steerer bung. We’ll correctly set up the headset and stem assembly too. Brake setup may apply.
  • Pedal fitting, £5.00
    Free fitting for pedals bought in store, removal of old pedals can be extra. If your pedals are seized in we can usually get them out, but occasionally either the pedal or crank may be damaged to save the important part. Charges dependent on job.
  • Fit Pedal Cleats, £8.00
    we will install the cleats to the base of your cycling shoes. This is free when you are buying pedals in store. If the old cleat bolts require drilling to remove, a charge of £15 will apply.
  • Puncture Repair (Fit new inner tube), £10.00
    We do not repair punctured tubes, for reliability and assurance we fit a brand new inner tube. As a part of this process we will find and remove anything that could have caused the puncture then inspect your tyre and rim for health.
  • Tubeless tyre fitting, from £20 to £35.00
    Fitting of a tubeless ready tyre to a tubeless ready rim. Valve and rim tape extra if required. we supply Stan's or Bontrager sealant as part of the labour charge.
  • Wheel True, from £17.50-£20
    Charge can vary depending on how badly your wheel is out of true.
    Extra labour may be charged if spokes are replaced, especially if we have to remove and refit such parts as tyre, cassette and disc rotor etc.

 



CLEANING

A dirty bike is always an unhappy bike; grit, sand and salt play havoc with the various moving parts on a bike. A clean bike isn’t just shiny paint work, it’s much deeper than that. While we’re cleaning your bike, we’ll also cast an eye over the bike and make any notes regarding its mechanical condition.

Bike Wash, £35.00
Don’t have the space or facilities to wash your bike at home? We can do it for you. We’ll thoroughly wash down a muddy/dirty bike removing road dirt, mud and salt. The bike is dried and re-lubed after to prevent corrosion. This does not include a drive-train de-grease, and if there is a large amount of oil/grease spread onto the frame from the drive-train, then the degrease will be required as it is a separate job with different products. This does not include any adjustments.

De-Grease, £55.00
This greatly reduces component wear as that black dirt building up is full of grit and carbon dust and acting like a grinding paste! Adding more oil just makes it worse too!
In a de-grease, all drive components are removed and cleaned in our friendly but effective parts washer. All dirt, oil, and grime including corrosive salt is removed and the parts will shine once again!
The Chain and other moving parts will be lubed/greased after the clean.
In this service gear adjustment may be required and is charged at half the usual rate at just £10. Sometimes new inner cables are needed if they fray on re-assembly.*

Full Valet, £80
Save £10 and combine the two above cleaning services. Have the entire bike brought back to its former shine! This isn’t just good on the eye but it ensures that your bike’s essential mechanical components are happy.
Chain and other important parts such as brake and derailleur pivots are re-lubed or greased after the wash.
Suspension seals are also cleaned and treated in this service.
Our full valet has a very good reputation, it may just be in the mind but the bike always feels ten times better to ride! 


 

HYDRAULIC DISC BRAKES              

Hydraulic Disc Brake systems have changed the “bike stopping” world as we know it, being super powerful and consistent. In the form of 2 or 4 piston systems very much like those on a car or motorbike, they are appearing on more and more bikes of all types. Whilst they do pretty much look after themselves, there are however some essential jobs that need doing every now and then to keep them in top form. Fear not, we can carry out repairs to get the best out of virtually any hydraulic brake system.

Disc brake pad replacement, £15.00
Disc pads are far more durable than rim brake pads but the time to replace will eventually come. We carry nearly every pad type out there, and if not we can get them. The pads will be replaced, the pistons returned to their neutral position and the caliper is checked for correct alignment.  Price of pads is not included and varies from brake to brake.*

Bleeding hydraulic disc brakes, £15-25 per brake
The fluid inside your brake can slowly absorb dirt and air, this hinders performance and if ignored for too long it can cause irreparable damage to the inside of your brake. In turn this can lead to poor performance or complete failure. The best way to avoid this is to have the brake bled. This process removes all the old fluid and flushes any dirt and air bubbles out. A thoroughly bled brake will have a much better lever feel, self adjust to pad wear and live a longer service life. Hint, if you notice excessive travel at the brake lever (pulling back closer to the handle bar) or any adverse noises from your hydraulic brake, have it looked at immediately! Charges vary dependent on make and model as they have different bleeding processes.

Hydraulic brake fitting, £15-25
Need an upgrade? If you want a better set of disc brakes, or an upgrade from cable operated discs? This service includes shortening and proper routing of hoses as well as re-bleeding after. We will fit a set of hydraulic disc brakes absolutely free when purchased in-store.

Disc Brake Caliper alignment, £10.00 per brake

Disc Mount facing (optimizing) £40.00
When a caliper is mounted to the frame or fork with an I.S mount, there is no way of adjusting the angle of the caliper. When this is mis-aligned the disc brake can be noisy and cause uneven/premature pad wear. The only way to rectify this is to optimize or face the surface of the mounts. This process removes uneven paint and actually cuts the surface where the brackets to the exact angle it needs to be. We use a Magura Gnann-O-Mat Disc Optimizer that attaches in place of the hub for perfect calibration. If your brakes are “post mounted” which is far more common on newer bikes there is very little chance of you needing this but we can check the posts anyway.


       

WHEEL BUILDING SERVICE - from £40.00
The wheel is by far the most important part of a bike, many high end bikes will have a wheelset that exceeds the price of the frame and this makes perfect sense.

Off the peg wheels these days are amazing but most experienced cyclists and shop staff will tell you that there is no better wheel than one hand built by an experienced wheel builder, for both ride feel and durability. No wheel building machine can rival the “touch” needed. A Bespoke wheel gives you the ability to choose the exact individual components for the riders needs. All our wheel building takes place in house at Geoffrey Butler Cycles by our Wheel Builder. He has over 30 years of wheel-building experience and has previously been listed as best wheel builder in the UK by the cycling press. We offer a large selection of rims, hubs, spokes and nipples from most manufacturers, we will order in rims and hubs to complete any build, and build wheels with customer supplied components.

We can also rebuild your existing wheels.

Please feel free to visit the shop and speak to us about you requirements or let us help you choose the right set of wheels for your needs.

SUSPENSION WORK
With many years of combined experience in store and as riders our mechanics are adept at working on and tuning suspension systems from all brands. Coupled with the use of suspension/shock refurbishment companies such as Mojo and TF Tuned we can get your Full Suss back on the trails.

We usually return specialized suspension units to their own HQ service department. For all other brands of suspension such as RockShox and Fox, we use TF Tuned and Mojo. All Companies have been outstanding with turn-around times and exceptional craftsmanship. Serviced units are returned to us looking and feeling like new with confident guarantees on all work. All frame/pivot work is done in house with high end tool kits. We are an official Specialized trained FSR service centre and have access to their frame specific tooling.

Prices can vary but typical charges are: Full suspension pivot and bush change, £40-80 Cost varies depending on bike suspension system, the price of bearing and bush kits are charged as an extra.* In some cases we will need to order the correct kit for your frame.

Fork service with Mojo or TF Tuned, from £100.00 We will ship your suspension fork to the best suited service company where it will be handled by the best in the business. The unit will be fully re-built with new oil, bushes and seals. Often internals are upgraded the latest spec. The fork will be dyno tested before return. Fork removal and re-fitting is extra, typically £25 as it involves the headset and front brake. Shipping is a separate charge.   

Rear Shock Service, £120.00
Shock removal and re-fitting is extra. Typically £15           

Rear Shock Eye Bush Replacement, from £20.00
Many rear shocks are mounted into the frame with bushes, these are like a bearing but as they don’t have to move as much or as freely as a bearing, they are solid with a coating for durability. When they are worn out you will notice some play or movement in the pivots at the end of the shock. Tightening the bolts will make no difference, they will have to be replaced before they damage the mounting hardware of the frame. This requires special tooling for removal and fitting, but that’s no problem we have it all! We do our best to stock bushes for most shocks and we’ll special order ones we dont. Suspension Tune/Rider setup - £20.00 If your bike’s suspension is covered in all the bells and whistles, it can be a little daunting to set up, especially as one adjustment can directly affect two others! “Red and blue dials?”, “what does the tortoise do?”, “why are there two air valves?” Here in the workshop we’ve seen it all before, so just give us your rider weight and we’ll do the rest. When we give the bike back to you we will be happy to explain the setup and any changes we’ve made. We’ll also give you some tips to alter the bike to your personal preference. Note. If your suspension is air sprung, you will need a special pump to keep pressures correct as it is slowly lost over a period of time, much like you keep the tyres at the right pressure. If you don’t have one, we can supply one.

 



BIKE BUILDS
                  

Build of a new frame and new components, £120-160
Cost depending on frame type and whether cables are internal or external, but we can get pretty much anything ready to ride.

Build of new frame with an electronic groupset, £150.00
We are fully trained in Campagnolo EPS and Shimano di2 electronic gear systems. We can install, tune and update firmware as well as customise shift profiles. We also carry a good selection of electronic parts and accessories.    

Fitting a new groupset and wheels onto an old frame, £120.00
Includes cost to strip down frame, clean and fitting of new groupset.    

Bike Build from Box, £40 to £80
We would ask all customers to collect their bike within a week of it being serviced or repaired. We reserve the right to charge for storage if bikes are not collected within a reasonable time. Bikes not collected after a 5 month period will be disposed of or sold to cover costs           

*replaced parts will be charged extra, we will try our best to quote for new parts needed when the bike is checked in. Our mechanics will call to confirm any prices for parts needed that may arise during the work on your bike. Work will only be finished after we have spoken to you.
