Salsa Cutthroat vs Surly Grappler
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Cutthroat takes the rack path; the Grappler takes tire clearance and price. Which matters more is your route, not a scoreboard.
Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.
Where they differ
4 of the 7 things we can compare come out differently. The rest are close enough not to decide anything.
Widest published tire
15mm more on the GrapplerThe frame figure, not the fork's — forks are routinely cut for more rubber than the rear triangle. Loaded, tire width is also seat-pack clearance: a big tire and a sagging pack compete for the same space.
Rear rack
Cutthroat is the one you can bolt a rack to without hunting for partsRead from each maker's own mount wording. An adapter is a real cost the price tag does not mention, and 'not published' is not the same as no — it just is not something to buy a rack on.
Chainstay
20mm longer on the CutthroatThe gap between seat tube and rear axle, which a rack, panniers and your heels all share. Longer is more room for a load; shorter is a more compact bike. Which you want is a preference, not a winner.
From
$1,950 between themManufacturer's cheapest complete build. Every spec above belongs to the frame and does not change between builds of the same model, so the cheapest build of the right frame is usually the right answer.
Side by side
Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
