Nitro Alternator vs Nitro Spirit

How they compare

Both boards are designed for all mountain riding. The Nitro Alternator uses a directional shape while the Nitro Spirit is twin. The Nitro Alternator has a camber profile (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise), while the Nitro Spirit uses flat (neutral base between bindings; predictable, often paired with rocker toward tips/tail). The Nitro Alternator is noticeably stiffer at 7/10 versus the Nitro Spirit's 1/10, suiting more aggressive riding.
