The Wraith Paycheck could be a comp for the Inversion, although it is not in the adventure category and lacks the the rack and fender mount options, and is considerably shorter, steeper, and lower than you’d want for loaded riding. It also does not offer thru-axle solidity.

That aside, the Paycheck frameset at $1.5k is $500 more than Inversion frameset, and undoubtedly lighter, though I can’t find exact numbers. I’d guess about a pound-and-a-quarter; CXMag built up a 19.6lb Paycheck with Rival and cable discs, while the Ultegra hydro disc Inversion is 21.something. I’m assuming the Inversion build-kit is heavier.
