is there any reason not to use a road bb for an mtb or vice versa ?
I've seen it suggested that the MTB ones might have longer threads in order to retain enough engagement when used with spacers on a 68mm shell. That shouldn't be a problem, but it might mean in some cases that you will need to tap the shell a bit deeper when using an MTB BB in a 68mm shell without spacers. There's no good reason to fuck about, so stick to road BBs for road cranks and MTB BBs for MTB cranks.
The #tester_approved quality level is Ultegra/XT, and they're both cheap enough that I can't be arsed to do anything but replace them.

best bang for buck shimano hollowtech bb ? would i be looked at funny if i used a ultegra level bb on an mtb ? is there any reason not to use a road bb for an mtb or vice versa ? do the mtb bb's have extra seals or extra protection for the bearings ?
and finally are some made so that you can pop the seals out and re grease ? i've got a bb noise on my roadbike with a da hollowtech. popped the seals out and regreased but it's still making a noise. thinking about replacing.
