Convert,

Yeah, I used to race, but now I'm a "bike owner", usually riding between 80 and 140 miles a week.

I noticed the crack, and called the LBS. They said to bring it in. I emailed Lori, at Serotta and explained what was going on. She asked me to have the shop call her once they got the bike. She gave the shop an RA number, and told the shop to strip the bike and send the frame back to Serotta. She made no promises, but told the shop that she would contact them after the frame arrived and was examined. About a week later, she called and said Serotta decided to replace the frameset. Apparently the damage was considered a design or build flaw. Serotta no longer makes Ti frames with the shifter bosses on the downtube.
