This Rockrider ST120 has a history
Entirely designed and developed in France at the B'Twin Village (Lille), this mountain bike is the fruit of the work of an expert team of passionate mountain bikers.
To best meet the need for comfort and ease expressed by beginner mountain bikers, the team created, designed, and tested the ST120, involving riders at every stage of the project.
Whether you're heading out alone, with friends or family, the fun of riding the ST120 mountain bike has been fully approved by users!

GCF FRAME
Because we've noticed that it's not always easy to get the right position on a mountain bike, our designers have created an entirely new frame that's easy to get onto for both men and women.
The CGF frame (Comfort Geometry Frame) is 100% aluminium for optimal comfort and excellent manoeuvrability. The slope angle has been designed to keep your back straight whilst the low rear ensures the bike is very agile when turning.

comfort and safe
We recommend that beginners wear cycling shorts with a pad (foam in the shape of a saddle) or a gel saddle cover to reduce soreness.
For longer rides, remember to take something to drink (e.g. a water bladder or bottle).
In all circumstances, even for a short ride, wearing a helmet is essential!
