    Cannondale bottom bracket noise

    I have a Cannondale Synapse Sport with about 1000 miles on it and the bottom bracket has recently begun making a creaking noise. I took it into the shop and they said it was the derailer rubbing the chain and made an adjustment. now it creaks AND shifts poorly

    I am taking it back in today, my question is: how long should the BB last? should it need repair/replacement after only 1000 miles of relatively flat riding?

    Thanks
    WTF man, WTF

    That seems awfully quick for the BB to be shot under light load, flatland, normal riding conditions....

    Two things:

    1) Have them fix the adjustment that they, seemingly, did wrong, and

    2) You/they should take another look at the likely source of the actual creak. Here's a couple of links to help with the pinpointing process:

    AND

    It's usually just a matter of patiently removing, cleaning,
    re-lubricating, and re-torquing fasteners until it quiets down.

    Thanks, I plan on having the derailer re-"fixed" at lunch and I'll talk to them about the BB

    aaahhhh, its quiet. the master wrench at REI took a look at the BB and began disassembling it right away. 45 min later its all back together, the derailer adjusted and I'm out the door for $0

    He said if it became noisy this summer at all, he would take care of it

    Sounds like ... he needed to grease/anti-seize/teflon tape the BB threads and re-torque them. Not at all uncommon.

    Welcome back. You'll have to find another way to measure your cadence now

    Yep, my old Cannondale has the same problem - wish I'd had a master mechanic, but instead I had me pulling the BB and replacing it three times to get it right. Lots of teflon tape and 3 years later = no creak.
