Workshop Services

Our workshop reception area, permanently manned by one of the team to handle small jobs and service book-ins and collections, is located directly inside the shop entrance while the main workshop facility is located on the top floor.


On the day of the service, we kindly ask to have your bike in the shop no later than 11am. We will strive to get your bike serviced and finished before the end of that day (depending on availability of spares). We would ask you to bring your bike in a clean state. The extra cleaning of bikes will be charged at £15.

You will get a phone call from the mechanic to confirm prices with you before any new parts are fitted. We will not continue with any work until we have spoken to you first, so accurate contact details are essential. Any worn/broken parts will be disposed of unless otherwise requested. Your bike must be collected 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.

Other Services

Apart from our standard services we can do almost anything to a bike that doesn't involve welding or brazing the frame - that's still the province of a framebuilder. The services are charged at £50 an hour - and we work to the nearest 15 minutes/£12.50. Among the procedures we regularly carry out are the following:

Headset service

Gear re-indexing
Brake re-alignment
Fitting new bottom bracket

Wheel Building Service

Handbuilt wheels are built for a purpose. They are built around the cyclists needs and wants and the conditions that the rider might face out on the road, pave or off-road.

All our handbuilt wheels are built in house at Sigma Sport. We carry a large variety of rims, hubs, spokes and nipples from all manufacturers such as DT Swiss, Chris King, Carbon-Ti, ENVE and PMP to name a few, and we will happily order in preferred rims and hubs to meet any specific requirements. We can also rebuild your existing wheels. Please contact us or pop into the shop and we will be happy to talk through your specific requirements or guide you in choosing your next handbuilt wheelset. There is a £50 charge for wheel builds.

Shimano Di2 and Campagnolo EPS Software Upgrade

We can update your current Campagnolo EPS or Shimano Ultegra Di2 software to the latest update and tune the system to provide new functions.

With this box of tricks we can run a full diagnostic check on your bike, we can speed up the shifting or slow it down, the choice is up to you! We can swap over the shifting buttons. We can also change the shifters over so the right-hand shifts the front derailleur etc... if you have a satellite shifter we can also change which derailleur it shifts and what button does what. The best feature is the multi-shift function which allows you to move the derailleur across the entirety of the cassette when you hold down the button. It makes a good groupset GREAT!

This new diagnostic will not work with the old analogue Dura-Ace 7900 system, but will work with Dura-Ace 9070 Di2.

The cost for this service is £25.

Please contact us to schedule an appointment, by email or by telephone on +44 (0)20 8614 9777 and select option 3.
