Arghh. Rode super six evo after washing and it creaks awfully. Have eliminated most obvious things such as qrs headset stem bolts pedals chainring bolts wheels shoes etc. are these bbs prone to wear or do the cranks need regular attention?

Yes- especially prone to wear/creaking especially the PF30 and Hollowgram crank combo.

Re-install crank or ne bb? I can't believe this has worn after 6 months use!

Probably not worn out, just need to reinstall with loctite as mentioned above.

Exactly, getting the tolerances to such tight standards for the BB itself and the outer diameter of the bearings is difficult.

Surprised more pressfit, bb30 don't creak.

Before you reinstall with loctite, perhaps take the crank out, clean, regrease and make certain the left hand crank bolt is torqued up correctly - 45 to 55nm i believe, this worked for my GFs Caad10 when it started creaking.

Where expectantly should the Loctite or grease be applied?

Regressing appears to have worked!

repacking with grease is only a temporary fix...like others have posted above, use Loctite 609 and be done with it.EM3
