With a traditional feel similar to the radical progressive action of the red cam, the Solo Red model offers a precise and frictionless feel for effortless action with enhanced rebound. The red cam shape allows the double-chain drive to adapt to your foots movement and delivers a fast, smooth stroke for longer playing and less fatigue. 4-Surface Control Core Beater Featuring a slim profile, the Eliminator Redline beater still offers 4 surfaces (2 plastic and 2 felt) but now includes an elastomer core to eliminate vibrations. Spring Adjustment Locks your desired spring settings and prevents tension changes during play. The rolling spring tension adjustment cradle allows the spring to pivot with each stroke for reduced resistance. Powershifter Function By sliding the footboard forward or backward, the revolutionary PowerShifter function provides 3 positions to precisely adjust the pedals power and feel. Instantly change the drive angle to create a light, medium, or strong feel. Universal Joint All Eliminator Solo pedals are equipped with Pearls adjustable universal joint, giving the secondary pedal the feel, power, and freedom of movement of the primary pedal. Patented Clamp Quickly fits various hoop thicknesses and allows side access for fast positioning.
