this bottom bracket is super smooth and looks great. The best thing about it is smoothness of it, i personally think i was one of the smoothest BBs I've ever had. It looks amazing too and the CNC machined spacers are super lite.
the only bad thing i can only think of it that is doesn't come in 19mm so if you got some Twombolts or other 22mm cranks you can't have then witch is a shame
over all i think this i a really good buy and i would suggest it to anyone with 19mm cranks. the only reason mine isn't on my bike is i got the mid size and i got a new frame witch has a Spanish bottom bracket.
