I like this bike a lot, but it has one issue that might have caused damage previously. The first few times I rode it, the rear wheel would pull out of the dropouts when climbing hard , not all the way but enough to cant the wheel sideways so it rubbed hard. I'd ride maybe a quarter mile or so that way thinking it was something else and the chain was severely crossed. Happened again the morning of the event as I had taken the wheel out and reset it for other reasons. I've found that I need to really honk hard on the skewer to get it to stay, makes it a pita to loosen. Anyway, thanks for the thoughts......I'm back on the road.
