It all runs very sweetly through a new sealed bottom bracket. I know that at 90kg, I'm no lightweight, but to have the seatpin bolt snap on a road bike was unforgivable. It took a while for me to find the right tyres. They gave a harsh ride, and were a little uncertain under wet braking conditions. After three months, the paper-thin sidewalls shredded, and I was in the tyre market again.
Continental Avenues are on the bike now, and they are great.
Several punctures were caused by inadequate rim tape on the new rear wheel. The curved-sideplate Shimano chain that came with the bike lasted considerably less time. I'm on my third rear cassette, and it looks like it will last a few months yet. I used to measure block life in terms of weeks, unless it was Shimano blocks. With them, I got less than two weeks before they were gone.
