Upgrade your road bike with this Shimano Dura Ace SM-BB7900 English threaded bottom bracket. Designed for Shimano compatible brands, this bottom bracket features a Hollowtech spindle type and a BSA (English) bottom bracket shell type.

I just upgraded some components on my bike and replaced this BB. There aren't any problems with it, I just gave my bike a bit of an overhaul.
