Summary: The unit connected flawlessly to my Garmin 910XT. I had to raised the sensor leg in order to detect the wheel magnet for the speed, but it was really easy to do with screw driver. Garmin provided two different bottom feet depending on the shape of your frame, which made the installation a breeze.
Summary: Quality product... now the 6th I've purchased for all our bikes. The design is low-profile, lightweight, and adjustable. It is very quick and easy to set up, and works flawlessly with our ant+ enabled watches (Garmin 910s) to see bicycle speed and cadence.
