PowerTap Elite+ wireless road wheelset plus CPU and chest strap $650
I have a complete PowerTap Elite+ system for sale. Wheels are 32-spoke laced 3x to Mavic CXP-33 rims. The rear hub is the PowerTap hub, the front hub is Shimano Ultegra. Wheels were built by Handspun, AKA Quality Bicycle Products in-house wheelbuilders. The rear wheel has about 7500 miles on it, the front way less, like maybe 2000 or less.
I also have the yellow CPU, the chest strap for the HRM, 2 handlebar/stem mounts for the CPU, and the USB cradle. If you want to get into power training for a reasonable price this is your ticket.
The hub is ANT+ so it will also work with other devices, like the Garmin Edge 500 and other Garmin models, plus probably other devices. You can have the wheels only for $550. Or take just the rear wheel for $450.
I live in Takoma Park, MD and work in Alexandria, VA.
