ROTOR

REX 2 MTB Crankset

  • Sale
  • MSRP $260.00


Borrowing its design from REX1, the forged and CNC'd REX 2 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 2.1 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.
