    Cranks and chainline....

    Building a SSCX bike. It's a 12x142. I'm looking at some SRAM CX1 cranks and they say:

    45.5mm chainline is compatible with 130 or 135mm spaced rear dropouts

    So what happens if I use this crank on my frame? The rear hub is a standard hub so plenty of room to move the cog around...but would I be better to look for a different crank?

    Would a crank that's 2x be better or any different? I'd be setting it up with a direct mount chainring if that matters.

    The whole crank and bottom bracket standards all over the place just has me flustered today so I want to make sure I'm not making another mistake ordering the wrong crank.

    142 is the same as 135. the only difference is that there are 3mm notches on each side of the dropouts so the hub can slide into place easily.
