When I first installed my cranks I greased the crankbolts and found that after a week a fixed/no brake riding that one side was loosening, so I tookem' out degreased the inside bb threads and bolt and used some blue loctite and torqued to spec., never loosened up again and I have disassembled it a couple times for cleaning without any problem (no seizing or anything). with all the salt that has been on the roads in New England I pretty much have to dismantle and clean my ride weekly. With this rain the salt should be gone now...thankyou mother nature.
