Wahoo Speed and Cadence Sensors
These sensors just work.
I needed Bluetooth sensors so that I could connect begin using TrainerRoad with my (non-smart) Kreitler Rollers. The speed sensor is required to calculate 'virtual power' and it couldn't be easier to install. By simply strapping it to the rear hub, around the axle. The sensor is activated by motion, and immediately connects with your Bluetooth enabled phone or via ANT+.
Batteries are CR2032 which are very commonly used. I've gone ahead and ordered a 20-pack from Amazon, since so many devices use this size.
