Gravel riding is inherently harsh. Vibrations from flint, dirt tracks, and technical singletrack wear down your body much faster than smooth tarmac. Many riders spend thousands on premium frame materials but choose a stock frame size based purely on a generic height chart, leading to lower back pain, numb hands, or knee strain. For a forever-bike material like titanium, a professional bike fit really helps to ensure all-day comfort on the bike.

Reilly Cleat Alignment and Bike Fit Service
Reilly offer a free, comprehensive cleat alignment and bike fit to all customers. This takes place at Reilly HQ in Westerham, Kent by an IBFI accredited bike fitter. After the fit, customers can demo as many bikes as they like on the roads and trails around the workshop.
A gravel bike sizing guide simply matches a rider's height to a static frame geometry chart. If you compare bike sizing to a professional bike fit you will find it is much more dynamic. A professional bike fit considers, amongst other things, the rider, how they ride, why they ride, their flexibility and riding style.
Two people who are 5’10” can have completely different inseams, torso lengths, and core strength. With an off-the-peg bike your body adapts to the machine. With a bespoke build, the machine adapt to your body.

Why is a Gravel Fit Important ?
Shifting terrain requires a weight distribution that keeps the tyres planted without sacrificing responsive handling. While titanium naturally dampens vibration, a poor saddle position or incorrect handlebar reach will still concentrate impact on your wrists and lower back. On a multi-day bikepacking trip or all-day Audax, a millimetre of misalignment translates to discomfort and fatigue over 100 miles. Reilly's range of Titanium gravel bikes and titanium frames are engineered to ensure all-day comfort.
We Start With The Feet
It is a simple thing but cleat aligment is essential, incorrect cleat aligment forces your body to adapt to an unnatural motion which can rapidly lead to pain and wasted energy.
