Nope, on pretty much every bike I have, if I have it on the biggest chainring and am seriously pushing, the top of the chainring visibly bends out. This seems to imply that the top of the chainring is providing most of the contact w/ the chain, which really shouldn't happen, but nonethless it does. This definitely happens on my Jamis Quest as well, and I've certainly seen it before.
Noone else does this? Maybe I should post in the Clydes.... Not only am I a very big guy, but I have quads to match, so I can generate some power.
