• @snottyotter @aniki Thanks for the responses, this is a bb I have had in the frame for a while (so pretty sure right shell, spindle etc). bb shell is faced on the ds and then the nds cup doesn't have a lip so i assume facing isn't important there - do you mean checking if the threading is parallel either side? Job for a shop?

    I took it out as I wanted to denitrol the inside of the frame and when I put it back it started binding. The daft thing is I can't remember if this is something that happened first time round and I just backed it off until it span freely, then subsequently forgot. Might try the campag route and locktite it in. Haven't died yet but it just seems like a pants solution.

  • I think that's a good option. Will try and find stock of UN55 but if you reckon the 300s are still decent I'll just try my luck with another
