One more solid stomp on the pedals to build momentum and the singletrack flows out before you in a sweet chaos of log rolls, whoop-de-doos, and rock piles. Your mtb is an accessory to your lifestyle; you´ve engineered your life to accommodate your riding, you should expect the same of your components. Borrowing its design from REX1, the forged and CNC'd REX 2.2 for your double cranks are enhanced by proprietary Trinity Drilling System (TDS) triple drilling technology to yield the perfect weight-to-stiffness ratio. We wanted to craft a mountain bike crank that could respond to whatever demands you throw at it. The REX 2.2 uses ROTOR’s UBB30 technology, offering a performance upgrade opportunity for almost all mountain bikes on the market – whether they were designed for 30mm cranks or not.
