Have any frame failures?
Word on the street is, that most bikes are max out at 200?
At just under 200,some of my rear wheels have not lasted.
A Velocity cyclocross rim ($$) the spoke pulled a chunk of the rim out!!! Miles from home, with a crescent wrench and disconnected brake, made it in.
Yes, I have and use a tension meter.
No problems with the frames. One the first, the rear bearings wore out. On the second, the front brake failed. One the third, the seat post bent. In each instance, the warranty place sent me a full refund and I got to keep the bike. Not bad.
