Cagey,
Verified purchaser

I found the InPeak power meter easy to fit. Once installed I downloaded their App and power meter was recognised within a few seconds. Once out on the bike it connected to my Garmin without any issues and seems to give much the same readings as previous power meters I have had.So far very pleased with this product.

    1. Hi Josh, This is built on the Shimano 105 FC-R7100 chainset and is designed for Shimano 12-speed road drivetrains. It isn't specified for 10-speed use. Many thanks Joe W
