Made me think about what other damage the exhaust

in future and there is *no way* I'm putting the CF
road bike on a beak, ever.

possible heat damage aside, I'd never clamp a CF bike around an area
that it's not meant to bear stresses. Ie: the top tube is not meant to
get crushed or deal with the stresses that it being fixed in the middle
will generate when you go over bumps etc. Keep it on the roof or
inside
