    Yes, I’m a bit worried about the bearings. I tried a normal 24mm rotor bb years ago and it lasted 10 minutes, so don’t really like the thought of one with smaller bearings, nor do I like the thought of spending £100 on a bottom bracket.

    I’d be interested if you have a job lot of bsa30 bbs sitting around that you’d offload at less than new prices!

    Really I want a 3d24 but they’re impossible to find (bit of a story - I have a 3d24 with q-rings and a pm Ive swapped between bikes for maybe 12 years. I’m tired of swapping, and don’t care about the pm so much, but still want q-rings. I’ve tried q-rings on a non rotor crank and the shifting was crap so inclined to stick with rotor. However you just can’t get a 3d24, but 3d30s are readily available)

  • Could you buy a basic one and the tool to swap the bearings out? Means you have bearing replacement capability and you can replace with a decent bearing when you need to. I run a BSA30 and only the NDS ever needs replacing so my Amazon bearing tool has come in very handy.

  • The frame is 24mm screw in, so bearing replacement is trivial. The problem is that I can’t find a rotor 24mm crank - but there are lots of rotor 30mm cranks on eBay. However I’d need bsa30 bearings - easy to fit, but expensive and probably less reliable.
