Recommend BB 68-121mm Octalink for Hollowtech cranks

Hi

I am currently using a Shimano ES51 Octalink bottom bracket, 68 – 121mm with my Hollowtech cranks on my Cannondale Prophet

I can get these BB's for £10 at CRC and they last quite long, but throughout most of their life, they grind and click, etc. There is no side to side play in them while they make the sounds.

I would like to get a quality quiet BB for it, don't mind paying a bit

Can anyone recommend a quiet, long lasting Octlinkk BB 68-121mm that will fit my Hollowtech cranks

Thank You

blackspire maybe-they made octalink cranks anyhoo-otherwise youre stuck with the big S.Might find nos es71's somewhere.

Thanks man
