The 2018 Wahoo KICKR Power Trainer is amongst the world’s best indoor bike trainers! This updated version offers more bike compatibility, espacially for bikes with disc-brakes and thru-axles. It also works with the new Wahoo Kickr Climb device, and has become completely silent, for a better overall experience. A new larger flywheel was specially engineered by Wahoo to provide riders with a realistic ride feel while training indoors. The Kickr also uses new algorithms to improve responsiveness. Pop off your back wheel and mount your bike on the direct drive for a smooth and quiet ride. The KICKR measures power (wattage), speed, distance and cadence. Use your smartphone to control the resistance for structured workouts or virtual course riding. Pain Cave, meet your new best friend.
