Inpeak Power Meter Shimano SLX FC-M7100 Powercrank

The Inpeak Powercrank Shimano SLX FC-M7100 is a single-sided power meter for MTB riders who want solid power data without unnecessary complexity. It measures on the left crank arm and suits bikes that are used regularly for training, trails or marathon riding. The system stays light and robust. In the SLX segment, this is often the economically sensible way to start training by power.

Who this model suits

This model suits riders who want to train by power on an MTB but do not need an expensive full system. It works for endurance training, intervals, marathon preparation and indoor sessions on a training bike. If you want to control workload properly, this model is often already fully enough.

Why the battery version makes sense

In everyday MTB use, a replaceable battery is often the simpler solution. You do not need to charge anything and can replace a flat CR2032 quickly. That saves time and reduces failure points. It is especially practical on bikes that may sit unused for a few days.

Compatibility and installation

The power meter fits Shimano SLX FC-M7100. The housing sits on the inside of the left crank arm. Around 10 mm of frame clearance should be available in the power meter area. For installation you need the Shimano TL-FC16 tool. You can find more matching models in our Inpeak category.

Single-sided measurement in training

The power meter measures only the left leg and doubles the value for total power. For training, load control and pacing, this is usually enough in everyday MTB use. A dual-sided system gives more data, but many riders do not actually need it. If you are only now moving into power-based training, this system is often the more sensible start.

Connectivity and daily use

The power meter sends power and cadence via ANT+ and Bluetooth LE. That makes it work with many bike computers and training apps. Automatic temperature compensation helps keep the readings clean in changing conditions. You install firmware updates wirelessly through the Inpeak app.

Alternative systems

If you want a similar Shimano crank-arm power meter, you can also browse our 4iiii category. Both systems follow a similar idea. In our experience, Inpeak power meters are more robust and come back less often as complaints.

If you prefer a pedal-based system, you can also browse our Favero Assioma category. For classic MTB use, the SPD-based Assioma MX series is especially relevant.
