Cranks MTB ROTOR REX 2.1

REX 2.1
Borrowing its desing from REX1, the forced and CNC´d REX 2 cranks are enhanced by proprietary TDS triple drilling technology to yield the perfect weight-to-stiffness ratio. The REX 2 used ROTOR´s UBB 30 technology, offering a performance upgrade opportunity for almost all mountain bikes on the market - whether they were designed for 30mm cranks or not.
