Trek Emonda ALR bottom bracket drag My trek Emonda ALR (Alu frame) bottom bracket has noticeably more drag (crank without chain will stop within one revolution of being spun) than my 2012 6 series madone.  Any suggestions?  I have adjusted the preload (to point where there is none) and it makes no difference. Bearings feel good; smooth with no rough spots.
Weirdly I noticed a lot more drag when I went from the old square taper to HTII external bottom brackets. My old square taper would spin "forever" and the HTII would come to an abrupt halt after only a couple of revolutions.

Apparently this phenomenon has a very infinitely small effect on performance.

With their measurement being 0.29 Watts to 1.64 Watts - which in the picture of things is nothing.

Your bearings may also be stiffer if they are newer as they do loosen a little over time.

If you have any other concerns - best take to a mechanic to inspect to make sure they have been installed correctly.
