Best of Both Worlds with GENIE

Poppy and Playful, plus a Bottomless DH Feel

GENIE is a patent-pending air-spring shock technology that we invented. It combines the control-enhancing linear spring rate of a coil spring through the “bump zone” with the progressive spring rate of an air spring at the end of the stroke to avoid bottom-outs. Truly, it's the best of both worlds – coil and air – with extra tuneability. Say goodbye to compromises and hello to the future of riding.

Eats Bumps Like an Enduro

16.3% better bump force management than ‘Bike of the Year’ Stumpjumper EVO

Eats Bumps Like an Enduro

16.3% better bump force management than ‘Bike of the Year’ Stumpjumper EVO

GENIE makes the Stumpy 15 ride like a bike with more travel because it actually does eat most bumps like a bigger-travel bike. For example, the Stumpjumper 15 (with 145 mm rear wheel travel) and our Enduro (170 mm travel) both use 101 mm of travel to absorb a 1080 N bump force. Same bump, same travel used, game changed.

GENIE Devours Bumps and Provides a Playful Platform

GENIE provides a platform you can trust in the turns or when pumping the backside. The second-stage rising rate makes for a fun, playful bike that can still plow like a bike with much more travel. Truly “best of both worlds” rideability.
