SRM PM9 Shimano MTB Power Meter
If you are looking for the ultimate power meter for your Shimano MTB crankset, look no further! The SRM PM9 Shimano MTB Power Meter brings SRM’s world–renowned power measurement to your Shimano direct mount crankset. Completely sealed from the elements, the SRM power meter can be used in the nastiest, muddiest conditions without fail. The power meter is accurate to 1.0%, features a rechargeable battery and is available in a 104 BCD spider design for rings ranging from 32-38T.
Key Product Details
Compatibility:
This SRM Shimano power meter is compatible with Shimano MTB direct mount cranksets using a 1x chainring. This includes the M9100, MT900-1, M8100, M7100, M6100 and MT610. Regarding chainrings, it requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many Shimano MTB cranksets). If you do not already have a 104 BCD 4-bolt chainring, you can purchase one with the power meter on this page. See Compatibility tab for more information.
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 SRM Shimano MTB power meter. It measures power from both legs, is accurate and reliable. Having said that, it competes with our power2max Shimano MTB power meters which are similar power meters, but are a bit more affordable. If you are an SRM fan, you’ll like this unit. Otherwise, you might give the power2max a try (also a great unit) and you will save some money.
Options
While not listed as an option above, you can bundle this power meter with a SRM PC8 Bike Computer. When you do, you get $249 off the standard price of the PC8. Please contact us if you would like this option.
Compatibility
Crankset: The SRM Power Meter for Shimano is compatible with Shimano MTB direct mount cranksets such as the M9100 series, MT900-1, M8100 series, M7100 series, M6100 series, MT611-1 and MT610.
Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many Shimano MTB cranksets). If you do not already have a 4-bolt chainring, you can order one with the power meter on this page.
If you purchase a new chainring with your power meter, we will bolt it on to your power meter before shipping, which will make installation that much easier when you get it.
