my 2006 ridley supercross scandium frame developed a nasty creak this past winter, on the bike commute to work, after one season of cyclocross racing. it got better in high heat and humidity so I assumed it was some gap being closed. so about a month ago, I broke down the entire drive train, cleaned everything, greased all the threads, with special attention to the mega exo BB threads. hopped back on and . . . creak-roink, creakk-roink, GAAAA.

talked to the shop guys who said a lot of creaking noises sound like the BB but could be anything, even the der hanger.

then couple days ago was at the hardware store and happened upon some pipe thread compound, and remembered something about titanium frame BB so decided to give it a whirl. broke down the entire drive train. cleaned, soaked, regreased everything . . . but this time, applied the pipe thread compound to the mega exo BB shell and BB threads . . . liberally. reassembled. the BB went on tight and gave it an extra little torque. hopped on and . . . no creaking, hooray!

I really don't have any question. just wonder if these press-on BB are prone to creaking and require regular reassembly, cleaning, and regreasing. anyone else have experience with pipe thread compound with press-on BB and scandium frames? I think it will be a bugger to get that BB back off . . . if the creakin starts up again.
