i posted this in the mechanics forum as well as ss/fixed gear and got no response. maybe this is too stupid of a question... i don't think it is, but i guess it's possible. and since i can't search:

so i'm new to this whole eccentric bb thing (or they're new to me), not sure if this is a problem or just a normal quirk. the frame is a gary fisher rig. i'm going on a longish multi-day ride at the end of the month and i want to make sure this thing is tip top. i only have maybe a few hundred miles on it.

anyway, when i'm pedaling hard out of the saddle, and especially when climbing, it creaks rather loudly with EVERY pedal stroke (right and left). i put a piece of tape going from the bb itself to the bb shell and slit it along the seam. it hasn't rotated at all in 50 miles or so, so i know it's in there solid. the way these things are secured in there i can easily imagine why it would creak, i'm just not sure if that's normal.

so it's not causing me any problems other than being noisy. should i be concerned and/or is there anything i can do about it?

...and while i'm here, i have a 3/32 chain and i want to bring some extras for a potential repair. the chain is a "KMC Z51 Rust Buster," and i'm thinking i should bring extra links and/or master links. what kind of master link can i buy that's compatible?

thanks

well iv never used an eccentric bb, but i have had bbs creak underneath me. it was an unsealed, square taper bb. in the unlikely case that yours is unsealed, i would suggest upgrading. otherwise, i dont know what to tell you. take it to your lbs man.

first step is disassemble, clean, regrease, re-torque.

Make sure it's not just the bolts of the pedals that are loose. (That is, the small bolts holding the platforms together, not the pedal shaft, or whatever that might be called)
