For sale/trade a Powertap SL (Wired) 32H hub, with wiring harness (sharkfin), cpu, and docking station. DOES NOT INCLUDE WHEEL , POWER AGENT SOFTWARE (can be download from Saris website), OR CADENCE SENSOR. This is for those looking to build up a wheel. I bought this used with the idea of building a race wheel however, the wheel of my choice has a 20 spoke count. Would like $500 obo/ono.
