Nitro Alternator vs Nitro Karma

How they compare

the Nitro Alternator leans more all mountain, while the Nitro Karma leans more freeride. They share a directional shape — different nose and tail; built to ride forward with better float in powder and drive on groomers. Both feature camber profiles — arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise. The Nitro Alternator is slightly stiffer, though both sit in the stiff range.
