Thanks, I contacted TrailCraft... We'll see what they say!Nothing off the shelf, but you can put something together using a Trailcraft 140mm or 152mm cranks (uses an aluminum 24mm spindle)

and Wheels Mfg BB92 to Shimano standard bsa bb adapter: https://wheelsmfg.com/bottom-bracke...-abec-3-bb-for-24mm-shimano-cranks-black.html
This setup works great with a lot of the chinese carbon BB92 and PF30 bb shell frames out there.
Lots of good stuff listed here.

You're right, Suntour has the ZERON 1-X. There's also the SRAM NX available in 155mm.I think Suntour makes some 152mm cranks. Maybe they fit what you have?
