• Think I need to get my bottom bracket threads chased as the NDS cup won't go in (been trying for 10 minutes, including five minutes of swearing). How much would an LBS charge for this, ballpark? Just wondering whether it'd be cheaper to buy (yet) another bottom bracket that is threadless instead.

    I'm assuming I can't/shouldn't attempt to do this myself, of course.

  • I've not got loads of experience with threadless BBs but my housemate uses one that I mounted into his Dolan with loctite and it hasn't come off yet, it's been maybe 9 months.

    Are the BB shell threads clean? A metal-bristled brush can help you dig out old greasy dirt. An angled pick is also handy. It can make the difference.

    They are a little grubby, but not filthy. The issue is the thread doesn't take, so the cup just keeps turning and turning without going in.
