Build strength and endurance on CycleOps' PowerSync trainer so you can take long pulls off the front of the pack or power up your favorite climb when spring comes. Connect with your phone, computer, or GPS (each sold separately) to track heart rate, speed, cadence, and power measurements; all the data you need to meet and exceed your goals. Its closed-loop resistance means you can choose a power output or slope and drill it for as long as the segment demands. A spring-loaded skewer system, wide footprint, leveling feet, and 3 easily adjustable clamping positions makes set-up simple and stable. And, with CycleOps' VirtualTraining you have the globe at your disposal to create and ride pre-existing, exciting routes and race against others; the possibilities are almost endless.
