I love the Pro Race2's on both my Nimbus and Corsa. But Probikekit doesn't have the 650c's (which my Corsa uses) at that price. I bought mine at bikeisland.com, $68 for two, including shipping.

I've been on GP 3000's as well for a year or two, after I bought a batch from a guy who was closing up shop. I've managed to wear some of them out without ever having a flat, which is the big plus. Recently put on some new 4000 "s" .. you can certainly feel the difference, they're a lot zippier. Will try the ProRace 2's next time, as I'm curious. FWIW, there's quite a difference between the standard 4000 and the "s" version based on the figures I've seen. The "s" is lighter, has lower rolling resistance, and more grip .. which is what we need of course.

I just bought a Giant TCR C1 and it came with Michelin Pro Race 2's. I like them a lot. I had been riding on Michelin Krylion Carbon Road tires. I can't tell a huge difference but I think I like the Pro Race 2's a little better. They're both very good tires. The Krylion Carbon Road tires are a little cheaper.

Pictures please!
