Rotor REX 3.2 crankset

€ 209,00 (including 21% VAT)

The Rotor REX 3.2 XC2 crank continuous to lead the 24mm crankset market in terms of performance and rigidity. It is one of the first cranks which have been designed with the input of a pro cycling team, proven by world champion titles. The "Closed Clamp Concept" has a left hand crank axle clamp saves weight and improves stiffness, while its trinity drilling system crank arms offers unsurpassed rotational and longitudinal bending resistance. Rotor's axle system has been specifically developed for multiple BB systems. In addition Rotor has extended the compatibility of the REX 3.2 XC2 because now it's featuring an improved ultra stiff 24mm steel UBB axle.

The "UBB System" is not a standard. It's all standards because it allows the installation of almost any 24 or 30mm Rotor axle crank on your bike, regardless of its BB type.


 Utilizing a special manufacturing process, named the “Trinity Drilling System,” an extruded aluminum bar is intricately CNC machined with three drilled holes through the length of the crank. The result is a unique triple hollow crank arm that enables Rotor to remove the excess aluminum in the core while still maintaining the structural strength of the crank.

REX 3 cranks can be used with Rotor QX-Rings (not included in delivery), but can also be used with any standard chainrings for 110/60mm standard bolt circle diameter.

Third generation of DTT (Double Thread Technology) technology in the left crank clamping system. REX 3 cranks have conventional assembly method but uses 3rd Gen DTT bolts which guarantee a reduction of stress rizers in the clamping area.

(BB and chainrings not included)
