A plus for the bear spray in this case was that while it didn't stop the wolf outright, possibly due to the improbability of being completely on target in this scenario, it sounds like it did slow the wolf down enough to allow the cyclist to ultimately get to safety. I would think the wide dispersion the bear spray provides was a significant factor in this.
