I think newer things have come along that are better than the velocis, which were good for their time, but outclassed now by things like Tioga Factory XC, IRC Mythos, Panaracer Fire XC, etc. I also figured that a semi was more suited to the breakdown of my riding now.
I got a new chain today. If I can get some new jockey wheels, I'll keep my existing ESP 9.0 because it works very well otherwise. I will leave off the crankset because I might get a new frame, and that could need a different bottom bracket, and I'd like to switch to ISIS from square drive, and don't wish to buy two bottom brackets.
