Clicking cog/chain, help!

Posted on
  • Right!

    I have sold a B.Jackson frame which I was using and brought myself a Merckx (steel frame)! I kept all the part from my old frame to put on the Merckx and brought a new chain and BB.

    Stronglight 200 crankset + Shimano Italian 72 107mm + Sugino zen chainring + Shimano dura ace track cog. All 1/8"

    After assembling everything, I turned the crankset and that is when I noticed the clicking sound! This noise did not happen when all the parts where on my B. Jackson frame.

    *Inspecting everything - I noticed *[I]as the chain was being caught by the cog, the chain was not falling between the teeth of the cog but slightly hit the bolts of the chain, and as the pressure continues it would force the chain between the teeth causing the click.

    If the teeth were hitting the sides of the chain it would suggest that my alignment was off. but this isn't the case as the teeth are hitting the bolts. The noise only happens when I am accelerating/climbing[/I]

    any ideas/suggestions/solutions/highlighting­ my ignorance welcome!

  • Is the cog old/worn? if so it may need replacing.

  • Good point, although I have a new cog on the opposite side of the wheel and tried running the chain on that but it still make the clicking noise!

  • Sunday bump!
