ROTOR’s INpower MTB now with DM rings and Bluetooth SMART
ROTOR INpower DM MTB Power Meter
The ROTOR INpower DM MTB Power Meter measures left leg power using two sets of opposing strain gauges in the axle. The strain gauges are able to measure power, cadence, torque effectiveness and pedal smoothness. Specifically designed for off road use, all of the electronics are located inside the water-proof, sealed axle. This makes the INpower DM MTB super durable and able to withstand the muddiest, harshest conditions.
However unlike the previous generation power meter, the new INpower DM MTB uses ROTOR’s Direct Mount Chainrings. The Direct Mount rings are machined from a solid block of 7075 aluminum which makes them lighter and stronger than the standard 2x chainring configuration. The ROTOR INpower DM MTB has ANT+ and Bluetooth SMART functionality, is powered by a AA battery with 300-hour battery life and features +/- 1.0% accuracy.
The ROTOR INpower DM MTB features ROTOR’s 30 mm UBB (Universal Bottom Bracket) design. This makes the power meter compatible with almost all standard frames when used with the correct spacers. In addition, when used with a Q-Ring, ROTOR’s OCP (Optimum Chainring Position) technology allows you to identify your OCP in order to fine-tune your Q-Rings for optimized pedaling performance and efficiency.
The ROTOR INpower DM MTB Power Meter is available in the following configurations:
- Chainring sizes: 38 | 36| 34 | 32 | 30 | 28 | 26
- Chainring shapes: Round | Q-Ring (Oval)
- Crank arm lengths: 165 mm | 170 mm | 175 mm
Please note – the ROTOR INpower DM MTB is only compatible with ROTOR Direct Mount MTB Chainrings.
The ROTOR INpower MTB has a 30 mm spindle and is compatible with the following bottom bracket standards: BB30 | Pressfit 30 (PF30) | BSA | BB89 | BB92.
