Rockrider RACE 900S mountain bike review

Dec 2023

Decathlon's in-house bike brand is Rockrider and this RACE 900S is a full-suspension, cross-country bike with specifications that will have you double-checking the price. A carbon frame, wireless shifting and specs that wouldn't be out of place on a bike twice the price. But, while it looks amazing on paper, can it deliver the ride of top options in the best mountain bike space?

The Flex 27.2mm diameter aluminium seatpost also contributes to its increased level of comfort.

Brakes

No matter what conditions you ride in (dry/wet), the Rockrider by Tektro 160mm double hydraulic disc brakes will come through for you, even in the mud. Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers. The aluminium brake levers are easy to grip and precise.
