Frameset

FrameThe ST 900 S MTB has a UNISEX frame.The ST 900's frame has been carefully designed down to the smallest detail, from the top tube's relatively pronounced slope, to the wide range of sizes (M: 1.65m to XL: 2m). The ST 900 S MTB is not only lightweight and comfortable, but UNISEX as well.To make the most of the improved comfort, the women on the Rockrider team recommend the 500 Women's Sports saddle, which is specially designed for the female form. - For less weight and more efficient pedalling, the Rockrider ST 900 S frame is made from 6061 aluminium (only 2.5 kg in size M without suspension). It is 200g lighter than the ST 540 S frame thanks to its double butted front triangle.Its 120mm rear shock uses a single-pivot system (more sensitive to small impacts, while remaining firm when encountering large impacts) and sealed bearings for a great lifespan.
SuspensionsThe 120 mm Rockshox 30 Silver hydraulic fork is 400g lighter than that of the ST 540 mountain bike. It is conical and offers even more stiffness and precision when steering. Easily adjust the fork's bounce and stiffness. Its quick COMBO LOCK lockout system, which you can control from the handlebar, helps prevent bobbing and loss of speed on faster sections.
