The old one was squeaking terribly so I had a new one put in about a month ago. That had a slight squeak under power, but it was minor and bearable. Then last weekend I washed the bike. Now it squeaks like a dozen mice. It was covered with mud and dust so I just put it up on the stand in the backyard and hosed it down. My usual method is a bucket full of water and dish washing detergent and a toothbrush but that would have taken hours given the state it was in. Never had a problem with the Fuji but that has an FSA sealed BB.
It’s worse early in the morning when it’s cold. It wasn’t too bad coming home this afternoon. Is there any cure beyond pulling it apart and regreasing?
I’ve had two, and have ridden the first one through a bunch of terrible conditions and it was silent. The only reason I bought a new one was because the first one was pretty much stuck in a frame. I have never greased or cleaned, cleaned either. Both cost me ~$30 each. I’ve used them in steel and aluminium frames.
ha, good luck, it could be ANYTHING
I thought my bb was done due to a creaking sound. After replacing it and the creak continuing, it turned out to be dirt in the seatpost binder bolt.
i’d pull apart and clean your chainrings/chainring bolts, saddle rails/bolts and your skewers/axle bolts before replacing anything else.
and FWIW, ive had gxp bb’s on about 5 bikes (inc a few that saw multiple winters as a messenger) and none of them skipped a beat.
FWIW not impressed with the durability of these GXP BBs, i get about 6mths commuting out of them before the DS bearing craps out. Previous Truvativ version I had lasted heaps longer - prob better seals or something.
+1. I thought my BB developed a squeak in NZ but the first mechanic I saw straight away said ‘rear hub’.
I can’t confirm whether or not it was because he cleaned out the hub and BB at the same time.
