I have an old Soma Generation that I have been trying to lighten and update (it has a cottered crank).
Has anyone updated or changed the bottom bracket on one of these or know the size of it? I would rather not take it out to discover that I can't find a replacement.

-thanks

i just got a soma generation bike can you tell me anything you know about the bike and the manufacturer its in excellent shape looks like it was barely ridden

It has the normal bottom bracket sizing (english 68mm)

However, the stem is not a extremely normal size
It's smaller than the normal 1" (I never changed mine out) -- it's .833" (21.1mm)

I haven't had any trouble with the bike (it's a soft ride) -- hi ten steel

I have it up on velospace: here -- it's not the most recent picture, but you get the idea

I ground off the rack mounts (I filled in the holes with weld first) and also filled in the rear brake mounting hole (you can see that on velospace)

why would you do that? You just ruined your frame.

but it looks good with no structural compromise~
