BIKE SIZING

If you are not sure which size of bike you need, as geometries have become ever more varied, we can help you to decide by gathering a few pieces of information.

There are two ways for us to help in assessing your required bike size: using your current bike, if you are happy that it fits you well; and/or by using a few key body measurements.

This field is for validation purposes and should be left unchanged.

Current Bike Information

If you already have a current bike with a set up that you are happy with please use the following form to send us the information below, so that we can map it to your prospective new bike. 

A, B and C are the most important ones.

If you have some reservations about your current set-up then please send us both your bike and body measurements so that we can compare the two.

bike measurements

Tip: Stand your bike as vertically as you can. Measure the height of the top of your saddle. Measure the height of the top of your handlebar. Subtract handlebar height from saddle height to give handlebar drop.

Body Measurements

Please enter your key body measurements below if you have reservations about the fit of your current bike, or do not have a relevant current bike to work from. 

A and B are the most important ones.

These details are not sufficient to optimise your final bike setup to the millimetre (this can come later), but it will help us to assist you, if required, in evaluating the correct base bike size.

The most important measurement when sizing a bike is your true inside leg length, from crotch to floor. Do not use your trouser leg size.

Tip: Stand barefoot with your back against a wall and spread your feet 6-8" apart. Place a book between your legs and up against the wall, spine up; raise it until snug against your crotch. Measure from the top edge of the book down to the floor.

Tip: Stand up straight with your back against a wall. Stretch your arms straight out to the sides, with arms parallel to floor. Measure from one furthermost finger tip to the other.

Specialist Bike Fitting

This page is all about helping you to decide on the size of bike that you need – it is not about detailed bike fitting or tuning of your riding position.

If you are experiencing persistent discomfort when riding, have an existing or historical injury that requires in depth biomechanical knowledge to address, or you are looking to optimize every aspect of performance, we would strongly suggest that you seek the help of an experienced specialist fitter after purchase – preferably after you have become familiar with how your bike rides.

The cost of a comprehensive bike fit can run to several hundred pounds and will take hours to complete, but a full bike fit from the right fitter equipped with up to date technology can transform injury recovery and avoidance, and deliver tangible competitive performance gains.
