ROCKY MOUNTAIN ETSX 50 '08

The ETSX line of bikes feature Rocky Mountain's Energy Transfer System(ETS) which creates a vertical path for the rear wheel to follow helping the rear end stick to the trail. Thanks to it's projected pivot point design the ETSX does away with pedal bob while increasing pedaling efficiency. The ETSX gives you the ability to adjust your rear wheel travel from 4" to 4.5" or 5" helping you adjust to the trail without changing your geometry.
