GravelTrophy_5d0066-Gravel Trophy _ Ugo Richard Photographe.jpg

On the material side, the Gravel Bike is at the crossroads of road biking and mountain biking.

The frame geometry is rather classic and is similar to a road bike.
However, the bottom bracket is slightly raised and the cranks shortened in order to more easily overcome obstacles.

The wheel arches at the fork and the rear seat stays are widened to accommodate studded tires with a cross-section of

up to 47 mm.

In terms of brakes, we often find powerful and safe disc brakes

Bicycle regulations :

To ensure your safety and the other participants, it is strictly prohibited to participate to the tests with :

- a recumbent bike (on your stomach or on your back)

- a bicycle with hanger extension
- a bicycle intended for time trials 
- a bike not suitable for Gravel


The organization strongly advises against the use of solid and stick wheels because the profile of the course does not lend itself to it !
