Have had Pro2 Race's on my C'dale since I got the bike. No flats in 2000km, but there are a few nicks here and there in the tread and sidewalls, but they're not large and I'm not overly worried about them. Will likely ride them into the ground and then switch to either Vredestein Fortezza TriComps or Vittoria EVO Open Corso CX's or Diamante Pro's for next season (in blue, of course).
