INPOWER REX 2.1

Your mtb is more than just an accessory to your lifestyle; it's your tool for training. Discover where you push hardest in your pedal stroke, despite varying terrain How you transfer power off-road will vary as much from the way you ride as to where you ride. The INpower REX 2.1 single chainring 1x cranks place power meter technology inside the crank axle where is protected it from loose rocks and other shocks, crashes, and outside contaminants like mud, sand, and clay. If you know your Optimum Chainring Angle, which you can find with INpower's TORQUE 360 and OCA pedal analysis, you can dial in your oval QX1 rings to your advantage. Forged and CNC-machined in Spain from 7075 aluminum alloy, INpower REX 2.1 for MTB features unprecedented data sampling technology, which takes into account abrupt changes in terrain like jumps and drops to accurately measure your power output.
