I've got a very lightly used SRAM NX 12-spd crankset available for sale: it was used for 4-5 rides on one of my bikes before being replaced. There are a couple minor scratches on each end of the crank arms, but that's it.

It comes with a 32t GX chainring, and has DUB spacing. 175mm length.

$50 picked up around Denver/Boulder, or will ship at buyer's expense. PM if interested.
