Hey fellow Swift-aholics.
This is my somewhat bi-yearly check-in. As you may or may not know, I've owned 2 Swifts since 2006, the first a silver one which cracked at the seat tube, and then a blue one which just recently developed a crack in the weld where the seat tube meets the bottom bracket shell:
I wouldn't say that I ride the bike particularly hard, but I can say that I ride it consistently, as it is my primary means of getting to work.
In praise of the frame design, there was no catastrophic failure, and I was able to cycle safely home. I actually didn't realize how bad the problem was until close inspection. When the crack occurred, the bike just felt as if I had lost air in the back tire.
Anyway, I've contacted Xootr support in the hopes that they will continue to honor the lifetime frame warranty in my case.
