Smooth bottom bracket. Threads were good and clean and installed without a problem. No creaking.

There is a mistake in the description. This is NO BB91 spec bottom bracket. This is the original spec Shimano Hollowtech/Truvativ/FSA 24mm BB. Please not this if ordering! The quality is acceptable and compatible with the above cranks. Price is reasonable and the bearings are smooth. Recommended alternative to factory BB.

I received the product like ordered. Everything seemed fine until I tried to fit it into my frame's shell... I received two right-threaded bearings!! I will unfortunately have to send it back and order a new one ://
