KCNC BB30 to Shimano Hollowtech BB adaptor
Does anyone have any experience with the KCNC BB30 to Shimano 24mm crank adaptor? This gadget includes the bearings with the 42mm dimension BB30 surface and 24mm Hollowtech crank surface all in one unit.
I have a BB30 road frame coming that I need to run a DA7900 crank in, and have been looking at the various adaptors available. I like the look of this unit, if for no other reason than that the press-fit is achieved by screwing the two cups together with the regular Hollowtech tool. Neat. But that's a moot point if it's a poor design or is unreliable or the bearings only last a month or something.
Appreciate comments. Thanks.

My KCNC BB adapter failed at 2000 miles. My first BB failure ever, however, I'm not sure what caused the failure.

The anti-friction bearings are producing plenty of friction. I'm getting a better opinion tomorrow.
