My wife has Kwest's on her Giant FCR. They seem like pretty good tires.

You're racking up the mileage, all right! I bought my San Jose commuter the same week you bought the Denali, and I have about 160 miles on it. I took the last 3 days off as a mini-break. So far mine only needed one adjustment--the lockring needed to be tightened a bit after a few rides (I ride it fixed).

I assume those aren't cartridge bearings (in the hubs)?
