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 2
Giant Revolt 2
1520 cm²
Surly Straggler 650b
1454 cm²

Front-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 parts

Surly Straggler 650b
Bolts straight on

Read 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 cage

Cage 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

Not compatible

A 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 2
Giant Revolt 2
430mm
Surly Straggler 650b
406mm

The 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.

Manufacturer'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.
