Surly Disc Trucker 26 vs Surly Disc Trucker 700c

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

The short answer

The Disc Trucker 26 takes tire clearance; the Disc Trucker 700c takes frame bag space 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

3 of the 6 things we can compare come out differently. The rest are close enough not to decide anything.

Frame bag space

394 cm² more on the Disc Trucker 700c
Surly Disc Trucker 26
1539 cm²
Surly Disc Trucker 700c
1933 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.

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.

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.
