Clicking comes while pedalling

Hi,

I've got a really annoying 'click noise on my cannodale - warrior900r.

Clicking comes while pedaling. If I pedal without too much pressure and concentrate on a cycling stroke, pushing and pulling, the click almost goes. Tied or lazy pedaling it comes back.

Can't find the cause - anyone got any ideas?

Tightened all this lot up to FT

- seat

- seat post

- handle bars

- new wheels

- new bottom bracket

- swapped pedals

- chain rings
Happy Cycling

    If it increases with pressure, perhaps the wheel, chainring or crank is flexing and striking something? I have the same problem on my fixie, right now, but I know why it's doing it and it's almlst certainly not the problem you have :)

    Concentrate on things that might cause this problem - a computer magnet, for example, a strap, a shoelace, the front derailleur cage.

    I had a similar thing and managed to cure it by removing the cranks, pedals and bottom bracket, greasing all the threads and spleens and reassembling.

    ... it's all straight and clean which is why it is so frustrating - no obvious visual clue to where it could come from.

    Just recreated it in by pressing the pedals - and have found it sounds like it's from the bottom bracket - which I have replaced to try to cure this problem

    The click noise ... sounds like.... you know when you are tightening something up and it gets to the point of no more tightening - that's the noise.

    Anyway... it's weird and annoying.

    Just spent 3 weeks trying to cure this myself - though you don't say if the click is once per pedal rev, or wheel rev, or other rhythm? Mine was once per pedal rev, definitely on the right foot downstroke. I stripped everything - pedals, chainset, BB, even the chainring bolts - steam cleaned them, then reassembled with grease or threadlock as appropriate. I also removed and re-greased and spray lubed the front & rear quick releases, as well as the seat clamp and saddle rail clamp. Oh, and I flooded the BB bearings with WD-40 then GT-40 just in case, although the BB is new and there was apparently plenty of grease still in there.

    It took me three repeats of the process above, becoming more mental about cleaning and re-greasing each time, to cure it. This morning's ride in - blissful mechanical silence.

    Whose spleens? Isn't that a medically risky procedure (if you're a surgeon, fair enough)? :D

    I hope you mean splines...

    Ha ha, yeah. I'm getting on a bit and figured that the clicking sound may have been coming from my own internal organs rather than the bike.
