Shop on Walmart


100% aluminum: the frame of the Rockrider ST 50 mountain bike has been designed in aluminum to combine strength and lightness. Thus, your pedaling is more efficient. Its "sloping" type geometry makes it easier to step over for both men and women. The 80mm front suspension lets you overcome your first obstacles with peace of mind on slightly uneven trails. This mountain bike has no rear suspension. It is a so-called "semi-rigid" mountain bike: ideal for starting and getting started on your first mountain biking tours. Faced with a "full suspension" mountain bike (with a rear suspension), the interest is simple: the mountain bike is lighter; you lose less energy on flat ground. 3 plates of 7 speeds, 21 speeds! 2 rotating handles that are easy to handle. On the left (trays): you manage the ascent/descent. Right (speeds): you adapt your effort more precisely. Triple chainring 22, 32, and 42 teeth + protection against grease. MICROSHIFT FD-M20 front. Derailleur -MICROSHIFT RD-M25. Rear derailleur -MICROSHIFT MS25 revolving handles, with speed indicators. SHIMANO 7-pinion cassette 14 to 28 teeth TZ500 Wide and solid chain KMC Z51. The saddle attachment (welded) of the ST 50 prevents any movement of the saddle during your ride. And because your comfort is our priority, we offer you an exclusive ERGOFIT saddle, wider, with a profile in the shape of a "hammock". Easily adjust your saddle height with the 350mm long, 29.8mm diameter steel MTB seat post. Brake effectively thanks to the 2 V-Brake type pad brakes. These brakes are made up of 2 calipers equipped with pads that exert a more or less strong pressure on the rim to slow down or stop the rotation of the wheels. Thanks to the specific design of the ST 50's aluminum brake levers, only two fingers are sufficient to brake. With its lightweight 26-inch single-wall wheels, you can easily get started on mountain biking trails. DRY 26 x 2.0 tires are the most suitable for hiking on dry terrain. The central part is very rolling, while their side crampons provide good grip in turns. Obstacles, wheelies, skids, small jumps? For your safety, wheels with "double wall" rims (more resistant) will be more suitable.
