MTB

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. INpower’s TORQUE 360 and OCA pedal analysis will show you where you apply force throughout your pedal stroke so that you can dial in QX rings to your advantage.

INpower’s integration in the crank axle protects it from air-bound rocks and other shocks, crashes, and outside contaminants like mud, sand, and clay. A key feature of INpower for MTB is its data sampling technology, which takes into account abrupt changes in terrain like jumps and drops to accurately measure your power output.

INpower records your data at a rate of 200 times per second and delivers the results according to your chosen settings via ANT+ protocol.

OCA

Knowing your OCA (Optimum Chainring Angle) will allow you to align Q-Rings' maximum gear ratio with your maximum force output.
