The new wheel was in the shop in two days. I just picked it up this morning. And not only was it a quick, painless, no-questions-asked warranty claim, but they upgraded me to the
Bontrager Race X Light wheel. That saves almost a half pound over the the Bontrager Race that came with the bike. And I did check -- Bontrager/Trek lists the wheel as having no weight restrictions. So I'm going to have an extra scoop of ice cream with my strawberry shortcake while watching the 4th of July fireworks tonight.
Now I just have a bit over three months to crack the front wheel rim so I can get that upgraded under warranty, too!
