Although Gary Fisher constantly proclaims that he invented 29er bikes, his collection has so far been limited to hardtails and the race fully "Superfly" - while other manufacturers already have 29er bikes in the all-mountain segment in their portfolio. Trek is now following suit for the 2012 model year and is launching the "Rumblefish", a touring bike with 120 millimeters of travel at the front and rear. Compared to the "Superfly" race bike, the new bike has a more upright riding position, a slightly higher bottom bracket and an aluminum frame.

The suspension kinematics of the "Rumblefish" are based on Trek's ABP technology, in which the rear wheel axle acts as a pivot point for the rear suspension. Trek's DRCV technology is also used in the suspension elements of the "Rumblefish". Thanks to an additional air chamber that only opens on hard impacts, Trek achieves a more linear spring characteristic and therefore a consistent response throughout the entire suspension travel range. Until now, DRCV has only been used in Fox shocks, but now Trek is also implementing the technology in the suspension fork. A Fox 32 Float is used on the "Rumblefish".

The components are XT brakes and gears from Shimano (30 gears), while the wheels and almost all other parts come from Trek's own brand Bontrager. A weight for the "Rumblefish" is not yet specified.
