Salsa Heyday! vs Trek Marlin 7
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Heyday! takes tire clearance and fork cargo mounts; the Marlin 7 takes frame bag space, the rack path 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
5 of the 7 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
95 cm² more on the Marlin 7Front-triangle area at the largest size, computed from stack, reach and seat angle. It is what decides how much full-frame bag you can run, and a frame bag is the one place weight sits low and central.
Widest published tire
61mm more on the Heyday!The 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
Marlin 7 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.
Fork cargo mounts
only the Heyday! publishes somewhere to bolt a cageCage mounts on the fork blades. This moves weight low and off the bars, which is where a heavy bar roll does the most to the steering.
From
$299.01 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.

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