Was easy to install. Only thing I would have liked is a torque spec.

The fine threads are very easy to cross thread and you will learn how to use a a mini triangle file if you're not careful. Once installed you'll love it.

Excellent reliable bottom bracket. I have used them on several bikes. I got another make last time...it turned stiffly and started to creak after a certain time of seasons. I expect this one to last many years.
