It's better suited to relaxed riding than pushing fast splits. In mountain-bike land, this is a pedaling-speed measure - how fast it rolls when you're working for it. It ends up here thanks to a fairly average weight, relatively narrow MTB tires that roll quickly, and a solid drivetrain that supports efficient riding. When you're pedaling, the tire setup is biased toward rolling speed on firm ground.

Uphill performance score: 9.5/10. Within Mountain bikes, it ranks near the top. On climbs, the lowest gear feels very easy. In numbers, the low gear is roughly 16.9 gear inches.
