Yeah, the Trek was an aluminum frame MTB and had very fat chainstays so the non-drive side crank arm had to be way outboard to clear them. The OEM bottom bracket was a Suguino cup-and-cone type installed "backwards" (i.e. the long side of the spindle faced the non-drive side) to get the crank to clear. When I replaced it with a cartridge I had to go all the way to 127.5 mm to get the nds clearance but, even at that, the chainline was ok enough to shift well.
