Smith Optics Trace MIPS, Aleck Crash Sensor

Long winding descents and race-day lead-outs, the Smith Trace bike helmet is all about versatility and crash safety.

Whether you ride road or gravel or take on extended bikepacking routes, it combines the advanced impact protection of MIPS® and complete 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. And when the day heats up, you'll stay cool thanks to internal air channels with intake and exhaust ports that keep the air flowing. Side channels let you securely stash your sunglasses when you don't need them, and when you do, our AirEvac™ ventilation system prevents them from fogging up.
