Bottom Bracket?

Hi all,

I just got a new rear wheel for my mtb converted to a SS. The bike was creaking terribly any time I rode uphill before the new wheel. I thought all the creaking would be gone since the bad rear hub is gone. Rode today and there is still some creaking but not as bad. Could it be a bottom bracket that is going? It is five years old and a SRAM GXP.

Thanks
 
I'll give you the same answer I gave you on MTBR.

Pull it out and grease the threads and while you're at it regrease your seat post. Then clean and oil your pedals and don't forget to check your chainring bolts for tightness either.

Creaks are like crickets, you always hear them but never know where they're coming from.
 
I checked everything over. I can't pull out the BB, don't have the tools. I dont have chain ring bolts, its a direct mount chainring onto the crank. Its either the headset or the BB. I can't get it to creak here by my house, I need a steep hill. Thanks for your suggestions.

I had all types of noises happening in my ride, finally gave up and took it to Jim Vreeland at HB in summit, had him change the bb, look the entire bike over 30 times and then he suggested that since I recently changed my chain the culprit might be my chain ring... sure enough when I got a new chain ring compared it to the old and there was very noticeable wear that was causing the noise with the new chain, but when looking at the old one without the new to have a side by side comparison I would of never noticed how badly it was worn. Same goes for the cassette, if any part of your drive train is newer then other parts of it, there might be the problem.
 
If your SS has sliding dropouts like in the pic below, check them. I had a creak on mine that I was certain was the BB, but turned out to be the metal-on-metal contact between the the sliding dropout and the frame. I put a thin film of grease on the dropout (then lightly wiped off to leave only a hint of grease) and the creak disappeared.

put it in a trainer and have a friend find the creak while busting it in/outof the saddle.
as mentioned, they come from everywhere, and it is hard to determine while standing above the bike/head moving while pedaling.
 
I had a creak in my seatpost that drove me crazy ( well it added to the list ) until I had to pull the seatpost out and found it when I put it back in.
If I did not need to put the bike in the jeep it would have taken forever to find...
