Great product to use with bluetooth cadence sensor and bike speed sensor. Purchase this product with Revain "Moofit Bluetooth Cadence and Speed Sensor ANT+ Wireless Cycling Cadence" to race with Zwift riders. Zwift is a subscription app, but it's a free demo to have fun with. Simply install this adapter in a USB3 slot and no drivers are required. Attach the Revain cadence sensors to the pedal spindle and one to the wheel spindle and complete the Zwift setup on your PC. The cadence sensor must be moving before it can be recognized by the PC adapter purchased and installed in the USB3 port and the Zwift PC application. Good luck and have fun!
