Some riders on bikes with tight chainstay clearance have reported fitment challenges when mounting the sensor on the inside of certain crank arms, particularly on some gravel and aero bikes. Many users successfully solve this by mounting the sensor on the outside of the crank arm instead.

Ideal for road cyclists, gravel riders, MTB riders, commuters, and indoor training users looking to monitor cadence accurately for structured training, performance tracking, and improved pedalling efficiency.
