yeah, 142x12 is not that old. the rear axle is non boost. you could run a boosted fork if you really wanted. But crank and wheels should be non boost.

O.L.D. = Over-Lock-nut Dimension as in the width of the rear axle.

OP, some rear hubs can be converted to boost spacing and others cannot. I just did it to my Hope Pro4 hub. What rear hub are you wanting to use?

Also, some people prefer non-boost cranks on boost frames to move the chainline inboard (closer to the center of the frame) to bias it toward lower gears. If the frame can fit it without hitting the chainrings it's worth a shot.

DT Swiss used to have a really detailed set of conversion charts on their website to identify which conversions are possible and which end caps are required but I can't find anything now. Very frustrating...

If it were a DT Swiss 350 hub, it'd work with a Wolftooth Boostinator or similar product as long as it's not the centerlock version but I'm not familiar with how the 370 is built. I'm guessing not since Wolftooth also makes a front hub version that specifies the 350 and 370 as being compatible, so YMMV. I'm sure someone has made a hack that works since it's just a matter of changing the spacing on each side by 3mm.

Yes, you just need spacers for the wheel. Search eBay and put in the different widths. You'll see.
