I'm ashamed to think how many miles are on my current set of GP4000's.

Those 5000's with less crr and a little smaller and closer to size profile is looking really good.

A few places online often run a two-for sale. I'll have to pony up pretty soon.

Ohhhhhh, try those 5000's with latex. Hnnnnnnggggg. It's a nice ride and lower crr on the 4000's per BRR website.
