Every Rockrider AM 100 HT is hand assembled at our own factory in Lille to ensure the best build quality for the most demanding rider.
SWITCH & RIDE: ONE BIKE, MANY RIDES: This MTB has been designed to work perfectly with its wide rims (Duroc 40) in 27.5" and its 2.60 tyres which offer an excellent balance between grip, comfort, and precision. The 27.5" and 29" wheels from our Switch&Ride concept are still compatible (11-speed version).
A UNISEX MOUNTAIN BIKE: Men's or women's MTB? This Rockrider AM 100 bike is unisex. For even greater comfort, our MTB team recommends the women's 500 Sport saddle, specially designed for women's bodies.

L: between 1.70m and 1.80m.
XL: between 1.80 m and 1.95 m.
If you are on the limit between 2 sizes: Choose the smaller size for easier handling and comfort (straighter back).

FRONT SUSPENSION: Have fun on technically challenging terrain!. Front Rockshox Sector Debonair suspension with 130mm of travel can be perfectly tuned up for each rider and riding conditions.

Drivetrain: SRAM NX drive train, 1x11 single chainring for lighter weight, more precision, faster gear changing, and greater durability.

The dropper seat post is height-adjustable, with 120 mm of travel, and can be controlled directly from your handlebars. The ability to lower the saddle in a flash with simply a flick of the thumb is a true advantage of the Mountain mountain bike. Feel free (and relaxed!) in your position on the bike during a technical descent.

Versatile tyre designed for all types of terrain: smooth, gravelly, muddy, dry, etc. More lugs to add grip in all weather conditions and well spaced to ensure they don't become clogged with dirt when cycling on muddy terrain. High side knobs for good grip when cornering hard.
Original front and rear tyres are Tubeless Ready.
PEDALS: The bike comes with B'Twin Flat Evo platform pedals. However, for improved performance when pedalling and for better control of the bike when cycling, we recommend replacing them with clipless pedals with platforms.
EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE: The front and rear wheels can be easily mounted and removed; all you need is a hex key (size 6). The rear derailleur has a clutch that locks/unlocks easily allowing you to easily attach or remove the rear wheel.

13.6 kg in size L, without pedals. 13.8 kg in size XL, without pedals. Exact weight may vary due to tolerances in the components.
As a guide the complete bike (MTB + fully equipped rider) should be no greater than 120 kg.
ADVICE FOR YOUR FIRST USE: During your first few rides, your bike's equipment will bed in (chain, derailleur, brakes, etc). We offer a free checkup within 3 months following purchase, during which our technicians will provide a 13-point inspection of your bike.
Weight: M - 165-174cm: 13 kg.
L - 175-184cm: 13 kg.

B'Twin Bikes
B'Twin are a popular choice of bike in the UK, partly due to their widespread distribution by Decathlon, and partly due to the value they offer. Their bikes are divided into several slightly overlapping ranges, with Triban best known for road and gravel bikes, and Rockrider gaining a reputation for high performing MTBs to suit every budget. Elops largely consist of a range of city bikes, whereas Riverside focus on hybrids. All in all, B'Twin bikes are well worth checking out given the size of their ranges; there's a model to suit most budgets.
Rockrider Mountain Bikes
Rockrider are Decathlon's off-road offerings, comprising of a series of kids bikes and adult hardtails, full suspension steeds and even a handful of high end E-MTBs.
This brand was launched in 2018, when Decathlon decided to split their B'Twin bikes into different genres. In terms of prices, there's something for everyone, with adult's MTBs starting at just over £200 and rising up to high end lightweight race bikes at nearly the £4000 mark.
If you want to ride off-road, and would prefer to buy from Decathlon, then the Rockrider mountain bike range is for you.
