THIS ROCKRIDER ST40 HAS A HISTORY
This mountain bike was fully designed and developed at the B’Twin Village (Lille, France) and is the brainchild of an expert team of mountain bike enthusiasts. To best meet beginner mountain bikers’ need for comfort and ease, the team created, designed, and tested the ST40, involving riders at every stage of the project. Whether you’re heading out alone, with friends or family, the fun of riding the ST40 mountain bike has been approved by users!
A UNISEX MOUNTAIN BIKE
The ST40 mountain bike is suitable for both men and women. Carefully designed down to the smallest detail, with a noticeable slope on the top tube, with a wide range of sizes (XS: 1.45m to XL: 2.00m), the CGF frame of the ST40 is light, comfortable, and very versatile. To make the most of the improved comfort, the women of the Rockrider team recommend the 500 Women’s Sport saddle that is adapted to women’s morphology.
A LIGHT, COMFORTABLE, FUN 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.
FRONT SUSPENSION FOR CUSHIONING LUMPS AND BUMPS
The Suntour XCT 80mm front suspension is designed for slightly uneven trails and helps you overcome your first obstacles with no worries. Its design, based on a mechanical spring, is reliable and easy to maintain. You can also easily adjust the stiffness using a dial.
REAR SUSPENSION: NONE
This mountain bike has no rear suspension. It is a “semi-stiff” mountain bike: ideal for beginners. Compared with a full suspension bike (with rear suspension) the benefit is clear: it weighs much less so you waste less energy on flat terrain. A semi-rigid mountain bike like the ST40 is the perfect choice for your first outings!
DERAILLEUR & DRIVE TRAIN: CHANGE CHAINRING AND COG
3 x 7 speed chainwheels, 21 speeds total! Left (chainwheels): control ascents/descents. Right (speeds): more precise control over your pedalling. In detail: Triple 22-, 32 and 42-tooth chainring + protection from grease – BTWIN drive train. -Microshift thumb shifters with speed indicator -Wide, sturdy KMC Z51 chain
STEM, HANDLEBAR, GRIPS: FOR GOOD HAND POSITIONING
With the 10° angled stem, the ST40 offers a higher steering position that is accessible and comfortable.
