XC riders living in France can now walk into their nearest Decathlon store and pick up the all-new Rockrider XC 900 S for just €1899!
B’Twin, Decathlon’s own bicycle brand, has released a new full-suspension bike that if launched in the UK would surely become one of the hottest bikes of the year. The Decathlon Rockrider XC 900 costs just €1899 in France, the only location it is currently available, which converts to around £1690, yet it boasts features not associated with sub-£2000 bikes.
The major selling point of the Decathlon Rockrider XC 900 S is the carbon fibre main frame matched to an alloy 6061 rear triangle providing 120mm of travel. This isn’t your standard Chinese bought catalogue frame though, and like most ‘high-end’ Decathlon models the XC900 was designed at the ‘B’Twin Village’ in, Lille, France.
A 1x specific design and overbuilt BB area should ensure the carbon main frame is stiff and efficient, though, with a Manitou Radium Expert metric shock attached to the rear (with grip shift lockout) and 120mm RockShox Reba fork up front, the Rockrider XC 900 S should remain fast and nimble for XC thrashing even in the rough stuff.
SRAM’s GX Eagle drivetrain gives the Rockrider XC 900 S its 1×12 drivetrain, mated to a Truvativ chainset with 34t chainring. SRAM also provides the stopping power with a set of 160mm discs front and rear and Level T calipers.
4 frame sizes will be offered ranging from S-XL and each size rolls on 29in, tubeless ready Mavic Crossmax wheels with Boost hub spacing and XC specific Hutchinson Skeleton 29 x 2.1in tyres. However, if you did fancy a little more cushioning or traction the ‘S’ in the model name stands for “Switch Concept” and the lightweight frame will accept 27.5+ wheels and tyres.
As already stated above, the Rockrider XC 900 S carbon XC bike is only available in France at this time, so if you fancy one you would have to pick one up while on your jollies. If you like the idea of a low-cost, carbon bike and aren’t bothered with rear suspension though, Decathlon UK does sell the XC 900 hardtail with similar spec but 27.5in wheels for £1499.99.



Very happy so far, couple of test rides and then a nice easy 30 miler.

@Wally, have updated the thread I started with a link to some pics to show tyre clearance.
