Jones Plus LWB vs Surly Karate Monkey

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

The short answer

The Plus LWB is ahead on tire clearance 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

5 of the 7 things we can compare come out differently. The rest are close enough not to decide anything.

Widest published tire

19mm more on the Plus LWB on 700c / 29in

The frame figure, not the fork's — forks are routinely cut for more rubber than the rear triangle, and compared only on a wheel size both frames publish. Loaded, tire width is also seat-pack clearance: a big tire and a sagging pack compete for the same space.

Rear rack

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.

Dropper post

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.

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.

Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
