Phil at Cyclepath Oakville has a set of 2007 Bontrager Race X-Lite Aero
Power Tap SL wheels for sale. There are about 800 km on the wheels. He tells
me that he wants $1,700 for the set but I think that he might accept a bit
less.

I've been riding with a Power Tap myself for a year and I can vouch that
it's a great training tool; as opposed to heart rate, power doesn't lie.
These come with the heart rate strap and the downloading cradle so you can
view the ride data on your computer.

Please call Phil directly at:
