Note to self: never ever think about Fuji bike again. A bike frame that is sensitive
to sweat? Jeez, who'd a thought? If it popped off the top tube and there are holes
there you could probably use something like a rivnut to reinstall with a bit of JB weld
or similar mondo epoxy under neath. Would not look great but would salvage the
ride. I assume an AL frame, not CF.
I have seen a number of CF frames a few years old with cover coats that look less
than stellar, and older bonded tube CF frames from the '90s had severe cosmetic
and sometimes structural problems at the bond between the CF tubes and the metal
lugs.
