Pre-Purchase Sizing
Stop buying bikes based on your height. Manufacturer charts are extremely inaccurate — we help you every step of the way before you buy.
Manufacturer height charts are extremely inaccurate — and they’ll push you into a costly mistake. We help you buy the right bike the first time.
The problem
Why sizing charts get it wrong
There’s far more to bike sizing than your height. Go on height alone — or stick with the same frame size you’ve always ridden — and you’ll get it wrong eventually.
- 01
Height isn’t position
Two riders who are both 6-foot can need completely different bikes — one upright for sportives, one aggressive for racing.
- 02
Geometry isn’t universal
A size 58 on one brand is not a size 58 on another. Frame shapes and stack/reach vary wildly between models.
- 03
Bodies aren’t proportional
Same height rarely means the same leg, torso or arm lengths. Those proportions decide how long and tall your bike should be.
The session
So how can we help?
We use bespoke fitting jigs — indoor bikes with completely adjustable geometry — to find the frame shape that actually fits you, then map it onto the bikes you’re considering.
- Dial in your ideal geometry on a fully adjustable fitting jig
- Transfer those numbers onto real bikes before you buy
- Compare a shortlist side-by-side so you know which frame fits
If you’re in the market for a new bike, don’t buy anything without speaking to us first.
Adjustable jigs. Real geometry. No guesswork.
