I’m either in the enviable position of having too many race wheelsets, or the completely unenviable spot of having to give up my toys.
I have -
Rolf Elan Aero Clinchers - 24mm rim, 1300 grams
Bontrager Race X Lite Carbon Aero Tubulars - 44mm, 1400 grams
Zipp 404 Clinchers - 58mm, 1660 grams
Just acquired the zipps, found a deal I couldn’t pass up.
Have been racing the Bontys for a couple of years, and have no issues or concerns, except that tubies are a hassle.
Like the idea of saving ~4 watts with the zipps, don’t like the idea of giving up 260 grams.
I would keep the Bontragers and sell the others, unless you race more than a few times a year, then convenience would drive me toward the zipp cclinchers as race wheels.
