SRM PM9 SRAM MTB Power Meter

The SRM PM9 SRAM MTB Power Meter is a great way to add power to your SRAM MTB crankset. This spider-based power meter measures power from both legs, is accurate and reliable. In addition, the upgraded PM9 version features improved accuracy, power balance, automatic temperature compensation and Bluetooth SMART. This power meter is compatible with 3-bolt cranks and fits both boost (52 mm chainline) and standard (49 mm chainline) frames. It’s compatible with 104 BCD round and oval chainrings.

Key Product Details

Compatibility:

This SRM fits SRAM direct mount 3-bolt cranksets. Regarding chainrings, it requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many SRAM MTB cranksets). If you don’t already have a 104 BCD 4-bolt chainring, we offer many that you can choose from.

Power Measurement:

This SRM power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, accurate to +/- 1.0%, 100 hours of battery life, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility. See Specs tab for more information.

Advice From Our Staff:

We really like this SRAM MTB power meter. SRAM 3-bolt MTB cranksets are very common and this is a great way to add power to them. It measures power from both legs, is accurate and reliable. Having said that, it competes with our power2max and Sigeyi SRAM MTB power meters which are similar power meters, but are more affordable. If you’re an SRM fan, you’ll like this unit. Otherwise, you might give the other options a try as they are also great units and you will save some money.
