I've had the bike since early January. I've got about 2600 miles on it so far. My last ride was 90 miles, all over southern Orange County. I checked the Zertz inserts on the fork and seat stays, and they're all solid. After this weekends double century, I'll probably try and get the seat post replaced by Specialized (hopefully it doesn't fail me on the DC). I clean and check over my bike once or twice a week, about every 150 miles.
