this is an odd one.

i was out biking today and i noticed as i pedalled, a clicking sound appearing to come from the crank. its a shimano compact 30/54 and i have shimano clipless pedals, the sort that you can use either side of. for the duration of the ride i listened to that annoying clicking and i put my bike away in the garage. i had to get my car out so this necessitated getting my bike out once more. i was wearing my trainers and when i pedalled the bike........no click :?

it seems the clicking only appeared when i was using the cycling shoes and was clipped in, use the trainers and its silent. i was going to contact lbs on thurs morning , but can anybody suggest what this might be ?

    ive read the stickied thread and will try lubricating the contact points between cleat and cycling shoe and see if it helps.

    My 1st view - possibly wear on the cleats, slightly worn ones will click if they're nearing the end of their life. Eventually they'll just pop out every time you use them. Tighten them into the soles a bit more - might cure it for a while. Replacements cheap enough from your local... CRC.

    which probably means it isn't 'crank creak'......

    Is it the same 'click' on either side of each pedal? Could also be that tightening the retention spring might help (but probably worn cleats...)

    Is it possible that your shoe is catching the crank as it goes past?

    You might be positioning your foot differently when you're wearing trainers.

    Make sure your pedal spindles are well greased and tightened well into the cranks.

  • Perhaps re-check the bolt connecting the cranks to the bottom bracket? I know I have to keep an eye on the ones on the Pylon8, with it being a square taper setup.

    I had the same thing. And, like you, the creaking wasn't there when I wore trainers - only SPD's.

    Strangely, it still turned out to be crank creak. I took the cranks+BB apart and lubed all the threads and the problem went.

    I can only assume that it was the extra strain from my being able to pull up on the pedals, as well as push down, that pushed things that little bit harder and caused the creaking.
