    Soma B-Side v2 owners, what size you running?

    I want to build myself a rigid 650b SS. The Soma B-side looks rad. I normally ride a 17" Kona. So naturally I've checked out the Kona Unit too but I'm liking what I see in the B-Side more. I'm 5'10" with a 31" inseam. Looking at the geometry it seems like I could go either way between the 16.5 and the 18.5. With the aggressive slope the top tube has I'm worried the 16.5 might feel small. Anyone my size tearing it up on a 18.5?

    I'm 5'8" w/ a 30" inseam. The 16.5 w/ a 100mm stem fits me like a glove. With your longer torso, it seems that you would probably roll with the 18.5 frame to keep from going silly-long on the stem. It is a great frame. I've had no trouble with it. A rigid fork in the 460-470mm a2c range would be perfect. The Soma 453mm fork would make it a sharp-handling mofo, if that's what you're looking for.

    Right on, thanks Carlos. That's what I was thinking. I'm definitely longer torso than legs and I'd like to run a 90mm-100mm stem. 18.5 seems right.
