Review on 🚲 XOSS Bike Cadence and Speed Sensor: Wireless ANT+ Bluetooth 4.0 Speedometer & Cycle Computer by Charles Julian

It's really thick as the cadence sensor is too thick to fit in my Shimano Ultegra crank, it hits the chainstay and down tube. I've found that when it's as close to the spindle as possible I don't hit it with my boot and it registers my cadence. Fits my iPad easily, but if your feet are wider than mine, be warned. Update: When I was riding in my sneakers, my boot kept bumping into it, so I ended up attaching it to my shoe. You have to position the sensor's horizontal axis more or less vertically for it to register, which isn't really surprising, but takes a star off my original rating.
