For sale is my wired Cyclops PowerTap SL power measurement system for a road bike. It includes a Mavic rim with double butted 14-15-14 DT Swiss spokes, and the CycleOps power measurement is done in the rear hub. Power, speed, cadence, distance and heart rate are measured with the system. The freehub is set up for a Campagnolo 8-10 speed freehub, but can be changed out for other manufacturers. It includes everything needed to set up your power based training. Cash or PayPal. Please reply with phone number and I’ll contact you to arrange a get together.
