Frequently Asked Questions

Which bikes are compatible with precision?

PRECISION needs 10mm of clearance between the crank arm and the nearest bike component. This isn’t an issue for most customers, but some frames do have tight clearance so pay particular attention when marking the installation location. Customers with bikes that have bottom-bracket mounted brakes might also have clearance issues. If you are unsure of fitment, even after following the instructions in your digital ship kit, you can request that we send you a physical ship kit, with a dummy pod so that you can make sure you have enough space.

What conditions can I use precision in?

PRECISION is waterproof and dustproof, and can be used in temperatures between 0°C and 40°C. PRECISION Powermeters can be stored at temperatures of up to 60°C.

The current PRECISION firmware version is 2.1.0.  To receive the latest firmware version on your PRECISION Powermeter:
