I am sitting on RS81 C35's with about 400 miles on them....
The story is somehow my skewer got put in wrong on my Mavic front hub. I had no Idea that mavic front hubs or mine was directional and it kept coming loose, being 2005 era, wheels with lots of use I bought the RS81 C35's. 1 month later I sold my bike I put the stock rs10's back on it. I now ride disc brake bikes. I have no use for the wheels, never put them on Ebay because I didn't ever feel like dealing with shipping.
Later on I figured out the skewer thing on the Mavics and now My nephew is riding the Mavics on a 1991 hybrid that I rebuilt into a XT 1x
Maybe someday I'll go back to rim brakes. Truth is I love my Single speed but I hate the flip flop wheels, freewheels.
I guess I am holding out for a decent price on a good Caad9 frame or other BB30 or PF 30 BB and I'll make a lightweight eccentric bb SS with the RS81 C35's
