Bottom bracket replacement for a single speed
 

I'm replacing my bottom bracket. It's going into a Surly Steamroller. The crankset is an SRAM Omnium. I'm told one from Phil Wood is compatible and is excellent quality. I'd appreciate any input from those that have made this similar switch or has a suggestion for a better choice.

Thanks

There is some math and measuring that can be done to anticipate best BB's to use when changing cranks or frames. But the best method is to trial install what you have and adjust from that. Andy

Phil Wood BB's are extremely good and long-lasting, but also quite expensive.

They also allow some chainline adjustment; many other cartridges do not.
