the new crank is an Origin-8 Trekking crankset, this one
and I can find /nothing/ technical on their webpile, nor was their anything in the box.
the crank I removed was a Shimano FC-M191,
which that says had a 47.5mm chain line (I didn't measure it before removing, DUH!), and uses a 122.5mm BB (wow, thats wide).
I measure my current chainline at 54mm, so...
54 - 47.5 == 6.5mm
122.5 - (6.5*2) == 109.5mm
so I figure I need a 110mm BB.
but yeah, if your friend can verify this, awesome. I have the bike ridable as-is with the funky chain line, just that the front derailleur is cranked out as far as it goes.
