Rated 5 out of 5 by Solid, reliable Good, reliable product from Shimano at affordable price. Maybe it is bit heavier than more expensive Bottom Brackets, but it comes with more strength and resistance to damage. Fitted my 22 years old Roadie perfectly and allowed me to upgrade chainset. 03 September 2013

Rated 5 out of 5 by iv had this over a year now and still like new, the rest of the drivechain has worn out around it, its just such a shame im changing crankset and need a different bb 26 March 2008
Rated 4 out of 5 by Stiff but not too durable I'm on to my third one of these now. I think each one lasts between 1 and 2 years depending on how much riding I'm doing. It's super-stiff, smooth, cheap, and very easy to fit, but doesn't last as long as square taper varieties due to the smaller bearings. This is the issue with Octalink and ISIS BBs: the fat pipe means less room for bearings and small bearings soon wear. But then at this price, changing it every year or so doesn't really bother me too much. 23 October 2007
