Rodeo Labs Flaanimal vs Surly Straggler 650b

Both published charts held against each other, on the specs that decide what the bike carries.

The short answer

The Flaanimal is ahead on frame bag space, tire clearance and dropper compatibility. Nothing here goes the other way.

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 8 things we can compare come out differently. The rest are close enough not to decide anything.

Frame bag space

193 cm² more on the Flaanimal
Rodeo Labs Flaanimal
1647 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.

Widest published tire

10mm more on the Flaanimal

Surly Straggler 650b
50mm on 700c / 29in, 50mm on 650b / 27.5in

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.

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

29mm longer on the Flaanimal
Rodeo Labs Flaanimal
435mm
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.

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.

Surly Straggler 650b — 54cm. Front triangle ≈ 1454 cm² · effective top tube 565mm · seat tube 540mm
Surly Straggler 650b in size 54cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1454 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.
