Our Verdict
On Cloudboom Strike
On Cloudboom Strike 2
The On Cloudboom Strike 2 is a substantial refinement over the original On Cloudboom Strike. Its softer tuning makes the ride more cushioned, energetic, and plush, though also less stable. Get the original if you find it at a substantial discount and don't need the fastest option or prefer the steadier ride. In most other cases, the upgrade is worth it.
