Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Problem after installing cranks & bb

So i am building up an IRO mk V. I got a miche bb and sugino zen messenger cranks. Last night i installed the bb and cranks and after i was done, i spun the cranks around to make sure everything was hunky-dory. When i spun it around there was a rubbing sound, and then the cranks would stop. I was once per rotation, and there was definitely more friction than there should be.

I might have tightened the bb cups too much, but other than that i cannot think of anything.

Any ideas?

Is it a loose ball BB? If so, it could be too tight or have incorrect 3 of ball bearings.
