B'Twin Rockrider XC 50 SX Eagle 29 MTB

This mountain bike is designed for starting cross country (XC) mountain biking.

Train with this XC 50 aluminium mountain bike, SRAM SX 1x12 drive train, Sun Ringle 29" wheels, and ROCKSHOX Judy 100 mm fork.

A UNISEX MOUNTAIN BIKE: Men's or women's mountain bike? The Rockrider XC 50 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.

CHOOSING YOUR MOUNTAIN BIKE SIZE: Comes in several sizes: S: between 1.50 m and 1.64 m.

XL: between 1.65 m and 1.74 m.

L: between 1.75m and 1.84 m.

XL: between 1.85 m and 1.95 m. If your height is on the cusp of the 2 sizes, we recommend the bike that matches your height exactly.

SWITCH AND RIDE: ONE BIKE, MANY RIDES: The SWITCH & RIDE system is easy: a mountain bike frame compatible with 3 wheel sizes.

1. You add a 2nd or 3rd pair of wheels. 2.

Enjoy all terrains!. This mountain bike is the fruit of the labours of an expert team of passionate cross-country mountain bikers.

Frame: The stiff, lightweight ROCKRIDER XC frame has optimised geometry for physical performance.

It was designed with shorter bases to leave space for wide tyres. Made of 6061 and 6013 variable thickness aluminium. Lifetime warranty on the Switch And Ride frame, single chainwheel only.

148mm x 12mm rear axle. Press Fit 92 bottom bracket. 31.6 mm diameter saddle tube.

Compatible with double bottle cage (except in size S).

Weight in size S: 1.5 kg.

FRONT SUSPENSION TO CUSHION UNEVEN TERRAIN: To overcome any obstacles you encounter, the Rockshox Judy Air fork and its 100mm travel will always be there for you.

Quickly lock and unlock the fork with the 2-position Combo Lock locking system on the handlebars. Suspension compatible with 27.5" and 27.5" PLUS wheels.

Drivetrain: The SRAM SX 1x12 drive train ensures light weight, durability, precision, and better control of your mountain bike.

Chainwheel size: 32 teeth.

SRAM PG1210 cassette with 12 cogs: 11,13,15,17,19,22,25,28,32,36,42,50 teeth. The 50-tooth cog provides an ideal ratio for climbing the most challenging sections.

HANDLEBAR / STEM / STEERING / GRIPS: Keep stable and find your attack position. The Rockrider Comp Flat handlebar is 720 mm wide for more stability. B'Twin Comp stem, resized for each frame size (60 mm in size S, 70 mm in size M, 80 mm in size L, and 90 mm in size XL).

Semi-integrated headset with sealed bearings. Lightweight, "lock on" style Rockrider 900 grips that screw onto the handlebar.

SADDLE / SEAT POST: Enjoy greater comfort when pedalling.

The ROCKRIDER XC / AM saddle weighs 265 g. Reinforcements plus the Ergofit system for added comfort. The seat post is 31.6 x 400 to allow compatibility with telescopic posts.

BRAKES: Exclusive Rockrider by Tektro hydraulic double-piston brakes. 180 mm disc front brakes, 160 mm disc rear brakes.

Equipped with a watertight rim strip that is Tubeless Ready compatible.

To switch to Tubeless Ready: add a Tubeless valve, preventative liquid, and replace the original tyre with the same model in Tubeless Ready (available in Decathlon stores).

TYRES: Grip and move over all types of terrain.

29 x 2.10 Hutchinson TORO 2 tyres.

Versatile tyre designed for rides on all types of terrain: smooth, rocky, dry, muddy. Special studs to optimise steering, and sufficiently well spaced out so that they don't get clogged with mud when riding on muddy ground.

High side lugs provide good grip in turns.

PEDALS: The bike is supplied with B'Twin Flat Pro platform pedals. However, for better pedalling performance, we recommend replacing them with platform clipless pedals (not included).

EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE: The front and rear wheels attach and remove in 1 motion: you just need a hex key (size 6). The rear derailleur has a screed that locks and unlocks easily to easily attach or remove the rear wheel.

WEIGHT: 12.4 kg in size S, without pedals.

12,6 kg in size M, without pedals. 12.8 kg in size L, without pedals. 12.9 kg in size XL, without pedals.

It is compatible with 3 different wheel sizes: 27.5", 29" and 27.5" PLUS. This mountain bike can hold two bottle cages (except size S).
