Has anyone fitted or had fitted Goldtecs Hollowtech II upgrade bearing kit? Thinking about sending my shells in to have the bearings fitted. Currently running XTR but experience a significant amount of drag with the current stock setup.

drag? You're doing something wrong.although ht2 is never going to be as free spinning as a square taper bb. Changing the bearings won't make much difference.

The only reason to change the bearings in shimano hollowtech cups is for duarbility not drag, drag would be caused by doing the preload nut up to tight or your BB shell hasn't been faced however the shell would need to be badly out to be noticable, ceramic hybrid bearings would be a bit better.
