Kona Sutra vs Surly Bridge Club
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Bridge Club is ahead on fork cargo mounts and price. 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
3 of the 6 things we can compare come out differently. The rest are close enough not to decide anything.
Fork cargo mounts
only the Bridge Club 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.
Chainstay
10mm longer on the SutraThe 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
$150 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.
