My husband commutes from Seattle to Kirkland, and puts his bike on the bus across 520 twice a day with no damage that I've heard of. His is, however, a pretty beefy frame. But ti is tough, right?
Ti is tough, but I have mostly Ultegra components that I don't really want to have to replace/constantly tweak... However, I may have to give it a try, because it would be super handy to be able to bus back and forth if necessary.
