What power meter will fit my Shimano XT MTB crankset?

There are several power meters that will work a Shimano XT MTB crankset:

 

Left Crank Arm Power Meter

Please also note, whenever you are installing a left side power meter crank arm, you need to confirm you have 10mm of clearance between the left crank arm and the chainstay in order for the sensor to clear. Please see the image below.

The clearance between the frame and left side power meter crank arm

Pros: Affordable, easy to install, don’t have to change crankset
Cons: Measures left leg power only

 

Spider Power Meter

These power meters are compatible with Shimano MTB direct mount cranksets using a 1x chainring such as the M8100. In addition, because they are spider-based power meters, they measure power from both legs.

Please note, the power2max uses a 104 BCD chainring configuration. So you will need a power2max compatible MTB chainring as well.

Pros: Moderately priced, VERY reliable, don’t have to change crankset, measures both legs
Cons: None

 

Power Meter Pedals

MTB power meter pedals can be installed on any MTB crankset. We have both the Garmin Rally XC and the SRM X-Power.

Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Cons: None

 

Crankset Power Meter

Of course, you can also choose to replace your crankset entirely for a new one. This is usually a more expensive option, but opens up the door to many possibilities. Here are our Crankset MTB power meters.

Pros: Accurate, reliable, measures both legs
Cons: More expensive, more work to install
