Since the business was established in 1956, the workshop has always been right at the heart of Geoffrey Butler Cycles. We aim to provide excellent service, quick turnarounds, and value for money on all servicing and repairs, from a quick gear tune all the way to full strip down and reassembly of the bike. Our two expert mechanics, who can count over 50 years of combined experience in the trade, are equipped and skilled to repair any kind of bike imaginable. From Downhill mountain bikes, Road Racing and Time Trial machines, to Dutch-style town bikes, to folding bikes, we’ve seen everything come through the GB cycles workshop and we have the tools and skills to get them all working at their absolute best.
While we welcome any and all repairs, our mechanics’ experience has given them sought-after knowledge to work on certain brands in particular. Expertise with Campagnolo components has always been a key part of the service we offer, continuing at present with both our mechanics having received training in setting up and maintaining the electronic EPS components from the manufacturer. Of course, Shimano components are the world standard and the market leader, and we have skills and experience to look after them all, including hydraulic disc brakes, internal-gear hub systems, and the electronic Di2 drivetrains. Whatever you ride and whatever riding you do, we are confident that when we service your bike, it will come back to you working exactly as it should. |
Gold Service
![]() £140 plus parts*
The Gold service is our most prestigious workshop job. Whether it’s an essential commute machine or your prized Sunday bike, with great care and skill we endeavour to give your bike its mojo back! The Gold service essentially includes nearly every service and cleaning element we can perform wrapped into one job making it extremely good value for money. We will carefully strip the entire bike down to the frame. Every single item will be methodically cleaned and inspected, this includes checking the frame and fork for any damage or cracks. We also check interior areas of the frame including head-tube and bottom bracket threads etc. The drive-train including crank set, chain, cassette, front and rear derailleurs will be cleaned in our friendly but effective parts washer to remove all old oils, salt and grime and will shine once again! Once we are happy that both the frame and components are ready, we start the re-build process. The headset is greased and re-fitted, new bearings fitted if needed*. When the stem and handlebars are re-fitted, contact surfaces are checked for corrosion, bolts are re-greased where required and tightened to recommended torque settings.
Brakes will be re-assembled and re-installed, new pads fitted if required*. Hydraulic brake systems may require additional work (leaks, fluid top up, bleeding, correcting sluggish pistons etc) charges can depend on the problem as well as the make and model of the brakes, we will always discuss this with you. The drive-train and derailleurs are re-installed and adjusted. All pivot points in the derailleurs will be re-lubed for smooth gear changing, 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. Brand new inner cables are fitted* and we would usually fit new outer cables to bring out the best in the components but if the existing outers are in good health then we will re-fit them. (cables are not included in price of service*). If you have a road bike with bar tape, the tape will have to be removed to fit new outer cables, naturally new bar tape will be required as it’s rare that the old tape can be re-used. In a Gold service we will re-wrap your bars at no additional labour charge. The bar tape will be charged for, but the choice of tape is yours. 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 then the wheels will be trued and dished. 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 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. This also clarifies that there are no clicks odr creaks present before signing the job off. |
Silver Service
![]() £70 plus parts* This is our most popular service and would suggest its done twice a year on bikes that are used regularly. The aim of the service is to ensure that your bike performs 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: Frame and fork checked for damage/cracks Spoke tensions checked and wheels trued. Tyres checked and inflated correctly. Inner and outer cables checked for corrosion, frays or wear inside the outer cable. Brakes checked and adjusted. Gears adjusted and the mech hanger will be aligned if required. Headset checked and adjusted. Seat post removed, cleaned and re-fitted with correct grease or carbon paste. Hubs checked for play and adjusted. (Cartridge bearings will need to be replaced if worn) Bottom bracket checked, pedals and cranks removed and greased before re-fitting if required. All bolts and fasteners checked and set to correct torque setting. For the silver service we would ask you to bring your bike in a relatively clean state. No cleaning is included in the £60 and if any cleaning is required to carry out repairs, it will be charged accordingly. It is becoming increasingly popular to take advantage of our cleaning services, for example we can remove and thoroughly de-grease the chain, cassette and chain set. This is far more effective than using home chain cleaning devices. The process carries zero risk of damage to bearings and paintwork as opposed to cleaning the components whilst fitted to the bike. This costs £45. We can also offer a full bike valet, a comprehensive clean at £70. Extras like this can always be discussed when dropping off the bike. |
Bronze Service
![]() £35 plus parts* The basic service is recommended for newer bikes or bikes with low use since new. It can include proper setup of a brand new bike purchased elsewhere. Brakes checked and adjusted. Gears checked and adjusted. Cranks and pedals checked and correctly tightened. Tyres checked and inflated correctly. Headset checked and adjusted. A visual check of everything else is carried out. Occasionally an upgrade to the silver service is needed if the bike requires it. We would try and point this out when the bike is dropped off or when our mechanics start work. |
How long will a service take?
We always aim to turn around any Service in a 24 hour period, as long as all spares or replacement 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, 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 ask you to collect your 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**.
*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.

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.

All our wheel building takes place in house at Geoffrey Butler Cycles by our Wheel Builder.

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.
