How fussy/temperamental is the pf30a bottom bracket?

22 Mar 2018 15:58

I'm considering upgrading my 2012 Cannondale Evo HM to a 2016 Evo. After 25,000km+ my old Evo still rides beautifully, and the bottom bracket has been dead silent and running perfectly ever since I put in a Chris King bb a few years ago. I'd like to try out the new Evo, but the prospect of having bottom bracket trouble/noise is very unappealing. Any input would be helpful.

I use King and Wheels Manufacturing bb's, PF30 and BB86. No noises here. King worked for you famously up to this point so I think you just answered your own question. General rule of thumb is to never use those junk plastic cup bb's from Shimano or Sram and you'll be fine.

Usually the BB shells for PF 30 are not very round. Then when you press in the plastic/nylon BB cups they will distort the bearings and cause them to grind.
