Nitro Alternator vs Nitro Doppleganger

How they compare

the Nitro Alternator leans more all mountain, while the Nitro Doppleganger 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 Doppleganger is slightly stiffer, though both sit in the stiff range.
