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 1.1 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 Narrow/Wide chainring.

UBB30 (30mm) axle and ROTOR bottom bracket systems ensure maximum frame compatibility. Cranks are available in 3 arm lengths including 170, 172.5 & 175mm. REX 1 cranks are manufactured in 7055 alloy, making them even more durable and stiffer/lighter than other cranks on the market.
