ok, i haven't swapped anything yet because i think it will be expensive to do.
i did convert the drop bars on the western auto bike to hybrid bars and put it on the trainer though so everyone in the family can ride it for exercise.
i also won some sweet 600b or c rims on ebay to swap with my wheels on my specialized when i do some events. i will ride the 26x1.9 wheels/tires for daily riding/exercising and keep those new ones for events.
21 bucks was the winning bid and 18 for shipping
"This auction is for a set of used Velocity Deep Vee 650 road wheels. The front wheel is 16 spokes the rear is 20, The rims are 30mm from the top of the brake surface to spoke holes. I was using them on my time trial bike but decided to pare down the stable. They are very true and can be used with either the installed Campagnolo cassette body or the inclosed Shimano body. A few minutes with an axle vise is all it takes to swap them out. They have Michelin Axial Pro tires on them right now. They hold air and have a few more miles left in them but the are more for the protection of the rims in shipping. The front weighs 1.06 kilos with tube, tire and skewer, the rear 1.26 kilos. They have never been crash and have been well cared for."
