Brillant buy

Fantastic bike. I upgraded form a sports trail bike (Rockrider ST540) which was great. I really wanted to get into cross country riding. This is a great bike light weight and not expensive for what you get

Fantastic bike

Its a shame its advertised with GX gearset, but the rear cogs are actually NX, however even with that considered, its very good value for money and hard to beat. Highlighly recommended. Only thing I've changed is the handle bar over to something with a bit of back sweep as was more comfortable for me. My mate Dave should defo buy this bike!

The story of the rockrider 500 cross-country mountain bike...

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 cross-country mountain bikers. The Rockrider team designed and tested the Rockrider 500 XC mountain bike with their mountain bike testers. For your satisfaction, the Rockrider XC 500 is assembled in our own factory in Lille, France, just a stone's throw away from our design team. For more information:

A unisex mountain bike

Men's or women's mountain bike? The Rockrider 500 XC mountain bike is unisex. For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.
