Design details

A COMFORTABLE, PLAYFUL 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. 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, while the low rear ensures the bike is very agile in turns.

DERAILLEUR and DRIVETRAIN

3 x 7 speed chainrings, 21 speeds total! 2 easy-to-use grip shifters on the handlebars. Left (chainrings): control ascents/descents. Right (speeds): more precise control over your pedalling. Details: -Triple-chainring chainset (22/32/42 teeth) + protection / grease. -MICROSHIFT FD-M20 FRONT derailleur -MICROSHIFT RD-M25 REAR derailleur -MICROSHIFT MS25 grip shifters with speed indicators -SHIMANO TZ500 7 cog cassette, 14 to 28 teeth -Large, solid KMC Z51 chain

FRONT SUSPENSION FOR CUSHIONING LUMPS AND BUMPS

Adjust the suspension hardness based on your weight, from 45 to 90 kg, to get over roots and stones more easily. All thanks to the UFIT concept (exclusive to Decathlon). Easy: simply turn the adjustment wheel! The 80 mm front suspension is designed for slightly uneven trails and helps you overcome obstacles with peace of mind. Its design, based on a mechanical spring, is reliable and easy to maintain.

V-BRAKES: BRAKE EFFECTIVELY!

The 2 V-brakes are made of 2 callipers that exert pressure on the rim to slow or stop the rotation of the wheels. Just two fingers are all you need to brake. One a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop.We offer a free inspection of your mountain bike within 6 months following the purchase of your bike.

27.5" WHEELS & TYRES FOR DRY TERRAIN: Ready to roll?

Take on your first obstacles! The wheels are effective and sturdy: 27.5", double-walled rims, 28 spokes (26", single-walled and 32 spokes in XS). The rim is lined for added durability and shock absorption. The DRY 27.5 x 2.0 tyres offer optimal performance with a rolling central part and knobs on the side to grip the ground on corners.

STEM, HANDLEBAR, GRIPS: for comfort

The 90mm long aluminium stem, with a 10° angle, provides maximum comfort! - The 620mm-wide steel handlebar provides stability and control. - The soft touch handles are comfortable to hold and provide good grip.

FLAT PEDALS

The Rockrider ST100 mountain bike comes with resin platform mountain bike pedals for added light weight and safety. If your foot slips off the pedal, there's less risk of bruising your shin.
