• The stock pedals on my new Cube Attain were aweful and started falling apart within a couple of weeks.

    I bought these to replace them:

    When I fitted them they seemed to be screwing in tight but I just carried on :| now one of the pedals has fallen off and when I tried to tighten it the hole was too big and the pedal spindle was moving in it freely. I'm not sure if these pedals were too big or if I just knackered the thread.

    So my question is do pedals come in different sizes? Should these pedals have been ok on my Shimano Sora crankset?

    How do I fix this? Do i need to replace the crankset ?

  • knackered the thread

    I reckon so.

    A Helicoil insert is one way out, but given the cost and effort you're likely as well off getting new cranks.

    Hey-ho, but it's better to learn from (relatively) cheap mistakes.
