SPINDLE POWER METER MODULES
The spindle type is the best protected and invisible power meter style and can be designed using these power meter modules. Easily much more accurate than arm based in 30mm alloy spindles due to the very clean torsion strain available for the sensor. Definitely the best choice for 3-piece modular cranksets and for gravel/MTB solutions.
SG53 MODULE
For spindle based power meter integration, we recommend the SG5x module. This is pre-certified and real-world tested in both very tough MTB pro-level environments and by multiple road brands.
This small module fits inside both 30mm and 24mm spindles. Combined with a round LiIon rechargeable battery and a set of shear-style strain gauges, this is the center of a very well-performing power meter product. A fully customized unique spindle based power meter can be put on the market in record time based on this module.
Differentiating features
- Single strain gauge bridge
- Integrated Micro-USB charging connector
- Two-color indicator LED
For factory calibration purposes, this module is compatible with the CalStand test and calibration machine.
SG57 MODULE
Our next-generation spindle based module is designed to be even smaller, lower power consumption, improved performance, and to be cost-effective for higher volume power meter products.

SPIDER POWER METER MODULES
SG72 MODULE
For crank spider power meter integration, we recommend the SG72 module. The great thing about spider-based power meters is the ability to measure the effect of both legs and simply tell how much torque is being used to pull the chain and propel the bike forward. This module is road tested and works very well for this style of the power meter.
Differentiating features
- Distributed averaging strain gauge configuration
- Supports magnetic charging connector
- Easy wire management
A dedicated calibration application is available for low volume manufacturing.

SG91 MODULE
Our next-generation spider style power meter module. Designed for high volume, lower power consumption, and better performance as well as easier assembly and test with full QC at every step of the manufacturing process.

CRANK ARM POWER METER MODULES
Crank arms are quite popular for power meters, but this is not the ideal spot to place a power meter for many many reasons. Accuracy is much more challenging in this position. The crank arm design and shape may seriously impact accuracy. Frame clearance can be an issue. For gravel and MTB, this position is very exposed to physical damage.
SG62 MODULE
This module compensates for some of the difficulties in measuring power in a crank arm. Combined with the right physical shape of the crank arm, this can be a very accurate solution.
Differentiating features
- Dual strain gauge configuration
- Supports magnetic charging connector
For best factory calibration and optimum performance, this module is compatible with the CalStand test and calibration machine.
For “pod-style” designs, we have several improvements available in a 2nd generation version.
