    My cranks are clicking. How do I fix it?

    My cranks are clicking and it's driving me mad! Every revolution when I put a lot of pressure on the pedals the left side clicks. I don't think it's the pedals because I recently switched them and the click is still there. I have a 2000 Klein attitude comp and I don't know what kind of setup it's got inside the bottom bracket. Please help me out.

    First things I would check are the crank arms - not uncommon for one to come loose, and it's not a big deal to re-tighten.

    If it's an original BB on a 2000 bike, it's likely in need of some grease in the bearings.

    If the crank spins freely without binding and/or being crunchy and no play, the bottom bracket itself is probably fine.

    What probably needs to be done is the following. Do one step at a time until noise is gone.

    Inspect all metal to metal contact points and apply grease as needed.

    1. Seat post to frame, seat rails to seat post clamp.

    2. Check the rear wheel skewer to make sure its tight.

    3. Remove pedals, clean and apply a light coating of grease to the pedal threads if you did not do this when you installed your new pedals.

    4. Check, tighten and possibly apply a light coating of grease to the chain ring bolts if you have the kind of crank that replaceable chain rings.

    5. Remove crank arms and bottom bracket. Clean the bottom bracket shell (frame) threads of all gunk/dirt/grime and apply a nice layer of grease to the threads. Clean the bottom bracket cups and re-install the bottom bracket.

    If the bottom bracket is a square taper, wipe the spindle off along with inside of the crank arm. Apply a light coating of grease to the bolts that hold the crank arms on and tighten down the bolts to the required torque spec.

    If the bottom bracket is a splined (Isis or Octalink) clean the crank arms and splines and apply a light coating of grease to the splines. Re-install the crank arms and tighten down the bolts to the required torque spec.

    Have a look here.

    Skewer should be cleaned and greased in addition to making sure it's tight as recommended above. The rear derailleur could also be the cause of the noise and is covered in the link I provided.

    Good luck,
    Pete
    I can barely get my mouth around it.
