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.

Innovative crank axle-based power meter. Power instrumentation is integrated inside the bottom bracket, protecting it from shock, crashes and the outside elements. Runs on 1 X AA battery for up to 300 hrs running time.

INpower is a left leg (single side) measurement only

INpower now affords mountain bike riders and 'cross racers the same pursuit of physiological gains historically enjoyed by road cyclists and triathletes.

INpower also maintains the bike's original aesthetics.

INpower can convert any 30mm ROTOR crankset into an axle-based power meter. Now for the first time, with a nod to toward ROTOR's flagship Q-Rings, INpower features TORQUE 360 and Optimum Chainring Angle (OCA) pedal analysis. Cyclists can now precisely and accurately assess force variations in their pedal stroke. TORQUE 360 and OCA values enable riders to orient their Q-Rings around their distinct pedaling characteristics taking advantage of their most productive zone.

INpower uses one standard AA battery and is equipped with the UBB30 axle system, a 30mm diameter axle, compatible with almost all standard frames in the market. Left arm option is available, so you can make your existing ROTOR cranks into a power meter, installation is easy via downloadable multi-lingual user manual.

Because it's centered in the crank axle, INpower achieves cleaner data transfer and greater accuracy via ANT+ protocol without suffering interruptions and temperature fluctuations. Sophisticated metrics like Torque Effectiveness and Pedal Smoothness determine total torque versus positive torque and average power versus maximum power respectively.

UBB30 axles ensure maximum frame compatibility, REX 2 cranks are manufactured in 7075 alloy.
