The progressive design of the Spark 2 is made for going outside, riding a new lap or finding a great single trail right nearby. The helmet shell equipped with large vents and internal Sweat Guide keeps the head cool, while the Ergo Fit adjustment system provides secure comfort. The adjustable visor blocks direct sunlight and also leaves enough space for goggles. No matter the adventure, the Spark 2 is an all-rounder helmet that is always ready to tackle the next trail. Ergo FitAfter a thorough revision, the ErgoDial is now called Ergo Fit. In addition to a significantly improved adjustment mechanism (no more pressing and twisting), it is now also much slimmer and more inconspicuous.
