Drop into banked corners, and roll flowy singletrack with confidence. Designed for those who embrace speed, the Smith Payroll mountain bike helmet offers complete coverage for enduro, trail, and E-MTB riders. This edition adds an Aleck Crash Detection Sensor. Integrated directly into the VaporFit™ size-adjustment dial, the crash sensor is purpose-built to register helmet impacts. It connects via Bluetooth to a companion phone app and can send a series of alerts to chosen contacts in the event of a crash. Designed to complement the advanced impact protection of MIPS® and zonal Koroyd®, the crash sensor technology adds a new layer of safety to your next ride so that you can focus on the trail. The lightweight design is E-bike certified, which tests helmets at higher speeds than traditional bike helmet certifications. Our VaporFit™ system lets you adjust the helmet fit on the fly, and the MIPS layer is integrated with the fit system for a snug, cohesive fit that feels great all day. Generous vents with internal air channels keep you cool while climbing and focused on the descent with fog-free lenses. The three-position visor accommodates sunglasses or goggles between laps or when the sun finally drops below the horizon.
