I have an old M739 chainset on my son's Cannondale. This is the one where the spider and outer chainring are one and the same and you need to change both to change one.
I bought this chainset and since being fitted the bolt holding on the spider keeps loosening off, and if I forget to tighten it he ends up with a spinning chainset. I think that either a locking ring or clip is missing.
Does anyone have a solution to this or on old knackered chainset LX/XT that is basically scrap so I can take off what is missing please
You can't buy happiness but you can buy a bike and that's pretty close
