Giant Revolt 2 vs Surly Straggler 650b
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Revolt 2 takes frame bag space, dropper compatibility and price; the Straggler 650b takes the rack path and fork cargo mounts. 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
6 of the 7 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
66 cm² more on the Revolt 2Front-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.
Rear rack
Straggler 650b 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 Straggler 650b 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.
Dropper post
only the Revolt 2 publishes dropper routingA dropper cannot be strapped to, so fitting one rules out almost every seat pack and leaves rail-mounted bags at a fraction of the volume. It is a capability and a constraint at once.
Chainstay
24mm longer on the Revolt 2The 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
$299 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.
