The Specialized BG Fit system involves a unique fit assessment process carried out by trained bike fit technician.

Our BG Fit technician has completed a BG Fit course and been fully approved by Specialized in the UK. Specialist fitting tools and ergonomically enhanced equipment are used as part of the advanced fitting technique.

You can have a BG Fit assessment on any brand of bike - you don't have to ride a Specialized bike to use this service.

Who can use BG Fit?

Can I get an assessment?

BG Fit is suitable for cyclists of any level. Whether you're a weekend leisure cyclist or a semi-pro, everyone can benefit from a safer, more comfortable posture on their bike.

Before booking your fitting, please note the following points:

If you're under 18, you'll need to be accompanied by an adult for your bike fit.

We can carry out assessements on male and female cyclists. However, please note that at present, we do not have a female bike fitter.

If you have a recent injury, you should wait until you are recovered before coming for your fitting.

What happens at the bike fit?

The three-stage process

The BG Fit process is a thorough and in depth assessment, so you need to allow two-and-a-half to three hours for your session.

Stage one Your fitter will ask you about your health and injury history. You will get the chance to discuss your cycling experience, skills and goals.

Stage two Your fitter will take a series of physical measurements and evaluate your strength and flexibility levels. During this process, he will look for any muscular or skeletal weaknesses, curvatures or misalignments which may be detrimental to your position on your bike. From these measurements the fitter can then look at changing the size or type of your contact points, for example your bar width and stem length.

Stage three Finally, you'll get a multi-dimensional 15-point fit with Z-Plane Assessment on a stationary trainer, to identify and improve rider asymmetries and knee tracking issues from all angles. Alongside the information already gathered, this fine-tunes your fit and can highlight less obvious discrepancies. Your fitter can then adjust the seat and handlebar height, stem length and cleat position to find the correct neutral position that will be the most comfortable and powerful. Your fitter will also analyse pedal and shoe placement and alignment on the saddle, for optimum performance with correct balance.

After your session

Post-fit feedback

At the end of the session, you'll have a tailored fit on your bike, detailed feedback and before and after photos.

Around two weeks after the assessment, we will call to discuss the effectiveness of the adjustments and, of course, we're on hand to answer any questions you may have before this.

Our bodies change over time, as muscles strengthen and gain or lose flexibility. This means bike fit is an ongoing process. At some point in the future, you may need to have another BG Fit carried out and your bike adjusted again. This will especially apply to beginner cyclists as they are likely to notice a more dramatic change over time.
