ROTOR REX 3 CRANKS
With a growing demand, ROTOR is committing to a separate mountain bike crank line named “REX”. The additional line, with its own designation and design will help to clearly distinguish the ROTOR MTB from the road crank line. The new REX MTB cranks are based on the same successful “Trinity Drilling System” technology as all ROTOR cranks, which helps reduce weight and maximize stiffness.
The REX 3.1 crank, the first number indicates the level, 1 being the highest, and the second number indicates the number of rings, in this case it is 1 single chainring, the new QX1 ring.
24mm steel axle gives Shimano standard compatibility, and cranks are available in several arm lengths including most common 170, 172.5 & 175mm. In addition, REX 3 are an excellent upgrade, light and stiff, they are the perfect entry in to the world of ROTOR!
