The Rumblefish is Trek's spin on the perfect 29er trail bike: reasonably light, capable of taking a beating, and as competent on the descents as it is on the climbs. While Gary Fisher didn't invent the 29er, the man and his brand have spent more than a decade tweaking wagon wheelers - and that comes across loud and clear with the Rumblefish. There are flashier models out there, but this bike is dialed.
As usual, Trek puts together a complete package that's filled with technological features from one end of the bike to the other. The Rumblefish is a fast bike anywhere that you can carry your momentum well, faster than many, lighter 26-inch bikes even. For long days in the saddle on rough trails, the Rumblefish will satisfy.
The Rumblefish slices through technical terrain where other long-travel 29ers bog down. While other bikes dive into their travel, the Rumblefish maintains an agile stance and snaps around sharp turns. The ABP suspension platform is impressive, active while we pedaled, descended, and especially while braking. Rarely will you find such high-performance suspension on a bike at this price. Fast nimble and plush, the Rumblefish is a breed all its own. Not only is this long-travel 29er one of the most versatile trail bikes we've tested, it's also a great value.
The Rumblefish II was simply the most amazing, spot on full suspension bike I rode in 2010. It not only did what it claimed going in, but with some of the new technology present on this bike, the Rumblefish redefined what could be possible with 29 inch wheels in a full suspension context.
