Steamroller BB question.....

This may be a silly question but i'd thought i'd ask none the less (braces himself for torrents of abuse).......

Any steamroller owners out there help me out with BB axle length?

Running a square taper Sturmey archer and plan to run fixed, is this something anyone could shed some light onto or are they 'too many variables' as i suspect?

Thanks in advance from a snowy Edinburgh.

Have a search for bottom bracket axle lengths that work with your cranks. Generally speaking it's the cranks that determine the axle length required, not the frame.

The snow isn't settling in my part of town :(

Hmmmm, a bit of googling came up with this.....

Looks like it gives a 42mm chainline with a 103 bb

....seems very narrow

Snows stopped and melted here (Marchmont) now :-/

My experience suggests you may want to try a 103mm and a 107mm (and maybe a 111mm) BB and be ready to run the chainring on inside or outside of crank spider to dial in the chainline.

(I have done this using a sugino RD2 -by design it should have used a 103mm, but i found best chainline was with a 107mm BB and the chainring on the inside of the spider).

My Roller is on a 111 BB and Sugino cranks, this has worked fine for me, I'd be surprised if there was clearance for 103 between the chain stay and the chainring.

dialled in!

Cheers guys!

I think my mate was a 103mm bb with some Sugino cranks on his. Messengers or something, they were 130bcd.
