Workshop Services


We provide service options at our stores both of which are fully equipped and staffed by a team of highly trained and experienced mechanics.

To book a service please complete a Workshop Booking Request and a member of our Workshop Team will be in touch with you to confirm your booking.



What you need to do and what to expect on the day of your service?

Please drop your bike off 24 hours in advance of your appointment or no later than 11am on the day of your service. We kindly ask that your bike be brought to us in a clean state. We do not offer a specific time slot to carry out the service on your bike. Should you wish to wait while you have your bike serviced please provide us with as much notice as possible. We will strive to get your bike serviced and finished before the end of that day - depending on the availability of spares. If we have to clean your bike, an additional charge of £15 per bike will apply.

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.

There will be a £50.00 deposit taken by our workshop team to secure a workshop booking. This is non-refundable if the appointment is cancelled within 48 hours of the day of your workshop booking. This deposit will go towards your final bill and if your bill is lower than £50.00 you will be refunded the difference.

Please note, the below prices exclude the cost of replacement parts.

Muc-Off Chain Optimisation Service

The Muc-Off Chain Optimisation Service is designed for those looking to get the most of their bike, eke out extra seconds and smash personal bests. The two services on offer allow our highly qualified mechanics to recreate the treatments given in the pro peloton and are the same treatments used by the likes of INEOS Grenadiers and EF Education-EasyPost. This programme utilises ultrasonic tanks which work to generate the best performance from all chains, this deep cleaning method will also increase the life of chains.

There are two levels of service available:

Ludicrous AF Chain Optimisation Treatment - At £50 this is the top level of chain optimisation for time trials and race days.

Hydrodynamic 2.0 Chain Optimisation Treatment - At £25 this is the second tier of chain optimisation for everyday riding.

Wheel Building Service

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

All our handbuilt wheels are built in-house at Sigma Sports. We carry a large variety of rims, hubs, spokes and nipples. We will happily order preferred rims and hubs to meet specific requirements. We can also rebuild your existing wheels.

Please use the contact form or visit one of our shops and we will be happy to talk through your specific requirements or guide you in choosing your next handbuilt wheelset


Please give us a call on 0333 006 8833 (option 2) should you wish to discuss any of our services.
