Genesis Mantle 20 2014

Born from our award-winning Core range and utilising the same highly-praised geometry as the High Latitude, Mantle is our range of lightweight, triple-butted 6069 aluminium-framed 29er hardtails. Bred with planted handling and a healthy dollop of playfulness the Mantle series lends itself equally well to fast and fun trail riding.

Using the same proven formula as the Core, we've dressed the Mantle 20 in a dependable, performance, trail-riders' spec; air-sprung, tapered steerer RockShox fork that's tuneable for rider weight, wide 700mm bar/short stem combo, powerful Shimano M447 hydraulic anchors and a full Shimano 9sp drivetrain.

The Mantle 20 and 30 feature a 6069 ALX triple butted alloy frame, the careful selection of tube diameters and wall thicknesses ensures the the frame is light and stiff, yet comfortable enough for long days in the saddle. An XX44 headtube keeps the steering precise and ensures the bike goes where you point it. Both models feature Shimano drivetrains, hubs and brakes throughout, as well as tapered steerer Rockshox air-sprung forks. These bikes take over from where the Core 40 and Core 50 left off, however the bigger wheels allow you to roll further and roll faster and provide the confidence to push your limits and progress your riding.
