Santa Cruz Chameleon vs Surly Karate Monkey
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Karate Monkey is ahead on frame bag space and bottle positions. 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 7 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
162 cm² more on the Karate MonkeyFront-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.
Fork cargo mounts
only the Karate Monkey 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. A frame with none published may still have them — it means the maker does not say.
Frame bottle positions
1 more on the Karate MonkeyThe maximum the maker publishes across sizes. Worth knowing before you buy a frame bag, because a full-frame bag covers most of them.
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.
