The story of the 100S all-mountain bike.: This mountain bike was fully designed and developed at the B'Twin Village (Lille, France) and is the brainchild of an expert team of all-mountain bike enthusiasts.

The Rockrider team designed and tested this Rockrider AM 100 S All-Mountain bike together with their MTB testers in the Vosges and the Alps. The AM 100 S is assembled at our own factory in Lille, just steps away from the bike design team.

Frame: The ROCKRIDER ALL MOUNTAIN frame offers 140 mm of travel on the rear wheel.

Its geometry has been optimised for steering: 66 degrees steering angle, 15 mm bottom bracket under the wheel axle. Made of 6061 and 6013 aluminium.

Lifetime warranty on the Switch & Ride frame: compatible with 27.5" and 29" wheels.

148 mm x 12 mm BOOST rear axle. Press Fit 92 bottom bracket. 31.6 mm diameter seat post.

Compatible with a bottle cage.

Weight in size S: 2.7 kg.

Front suspension: Rockshox 35 Gold fork with 150mm travel.

With new Burly 35mm damping rods for more stiffness and control, and a DebonAir (TM) pneumatic spring (which reduces rubbing), the shock absorption and response to loading are increased. Compatible with 27.5" and 29" wheels.

Rear suspension: Manitou McLeod Air 190X51 rear shock designed specifically for the Rockrider AM 100 S mountain bike.

Adjustable to reduce bobbing during long climbs on faster terrain. Drivetrain:. SRAM NX drive train, 1x12 single chainwheel, for lighter weight, more precision, faster gear changing, and greater durability.

Rack: 34 teeth (for the 2020 model), 30 teeth (for the 2021 model), compatible with 30, 32, or 34 teeth chainrings, accessible without having to change the chain.

Cassette: SRAM Eagle in 11-50 (11-13-15-17-19-22-25-28-32-36-42-50). The 50-tooth sprocket guarantees good gear reduction to help you climb the steepest slopes.

Riding position: Control your steering & stay precise. Rockrider Comp Flat handlebars, 760mm wide for greater stability. 35 mm stem.

Semi-integrated headset with sealed bearings. Lightweight Rockrider 900 "lock on" grips (attached to the handlebar with a screw-on system).

Brakes: SRAM Level T brakes, with the 4-piston brake calipers designed to cope with the most demanding terrain, offering improved bite and modularity.

180 mm front disc, 160 mm rear disc.

Saddle and seat post: The Rockrider XC/AM saddle has an Ergofit system for greater comfort while pedalling.

The height of the dropper seat post can be adjusted using the control on the bike's handlebar: 120mm of travel in size S/M and 150mm in L/XL.

The ability to lower the saddle in a second with a single press of the thumb is a real advantage for all-mountain biking. Feel at ease (and relaxed!) in your seating position on the bike during technical descents.

Wheels: Sun Ringle Duroc 30 wheels, with Boost axles, 15 mm at the front and 12 mm at the back.

Outer rim width: 30 mm. Watertight bearings. Equipped with a watertight rim strip that is Tubeless Ready compatible.

To switch to Tubeless Ready: simply add a Tubeless valve and tyre sealant. The original tyres are already Tubeless Ready.

Tyres: Hutchinson Taipan 29 x 2.25" and Toro 29 x 2.35" tyres.

A versatile tyre designed for riding on any type of terrain. High side knobs for good grip in the turns. Tubeless Ready.

Pedals: The bike is supplied with 520 Grip platform mountain biking pedals (ref: 8487130). However, for improved performance when pedalling and for better control of the bike when cycling, we recommend replacing them with clipless pedals with platforms or wide aluminium platform pedals.

A UNISEX MOUNTAIN BIKE: Men's or women's mountain bike? This Rockrider AM 100 S mountain bike is unisex.

For extra comfort, the women from our MTB team recommend shortening the handlebars, which will make the bike easier to handle.

Transporting your 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: S - 155-164cm : 14.3 kg.m - 165-174cm : 14.4 kg.

L - 175-184cm : 14.6 kg.

XL - 185-195cm : 14.9 kg (bike without pedals).
