Whether you ride for routine fitness, focused training, or just for fun, the Smith Triad bike helmet has you covered on the road with innovative crash safety features and tunable comfort.

The Triad combines the advanced impact protection of MIPS® and zonal Koroyd® with an Aleck Crash Detection Sensor for a new level of safety. Designed 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. Tunable comfort comes from our VaporFit™ system which lets you adjust the helmet on the fly with the turn of a dial. The MIPS layer is integrated with the fit system for a snug, cohesive fit that feels great all day. Nineteen vents with internal air channels maximize airflow to keep you cool and your glasses fog-free through any level of effort. Little details like integrated sunglasses storage and a low-profile strap divider make a difference in convenience and comfort on the bike.
