Update your existing 3D30 crank to a power meter with the addition of the left arm only.
The INpower 3D30 cranks feature the latest metrics to interpret your data through user-friendly software and advise you when to punch it, ease up on the pedals, do another interval or head home. Seamlessly integrated inside the crank axle for your 30mm BB, the INpower 3D30 is protected from impacts, crashes, sand, mud, snow or whatever else you can throw at it, plus it's out of sight for a more aero look and feel. The forged and CNC’d cranks are enhanced by proprietary TDS triple drilling technology to yield the perfect stiffness-to-weight ratio, and its compact crank spider offers a wide range of chainring compatibility without compromising stiffness.
