With regards to the new splined Shimno BB's...
I recently took delivery of a new steel frameset from a well known framebuilder. I had them install
an Ultegra 9 speed BB for me. When I spin the bottom bracket by hand, it spins smoothly, ubt with a
good amount of resistance. Nothing like the free turning ball bearing cup BB's from the early 90's.
I have another bike with the same model bb, and a DA crankset installed. I never got to turn that BB
by hand (shop installed the BB and crank at the same time), but when I spon the crank without a
chain on it, I notice similar results, spins smooth, but with enough resistance that it stops fairly
quickly. Is this normal for these? Do they need to be worked in? Seems to be an aweful lot of
resistance. Are these BB's pretty much 'plug and play', or is there adjustment for this??
Thanks!
