Trek Rally WaveCel Helmet

WaveCel is a collapsible cellular structure that lines the inside of the helmet. Unlike traditional EPS foam that primarily manages direct impacts, this structure is designed to flex, crumple, and glide to help reduce rotational forces during an accident.

Yes, the Rally WaveCel includes an integrated Blendr mount system. This allows you to easily attach compatible cameras or lights directly to the top of the helmet for a clean, secure setup.

The Fidlock buckle uses a magnetic slide mechanism that snaps into place automatically. It is designed to be operated with one hand, making it much easier to secure or release while wearing full-finger mountain bike gloves compared to a traditional plastic clip.

The visor features three distinct positions, allowing you to push it up far enough to park your goggles on the front of the helmet when you aren't using them. It is specifically designed to accommodate both goggles and sunglasses.

Yes, the Rally WaveCel is built with deeper rear coverage than standard road or cross-country helmets. This extended shell design provides extra protection for the back of the head, which is a common impact zone during mountain bike crashes.

This helmet uses the BOA Fit System, which features a dial at the back of the cradle. You can easily tighten or loosen the tension with one hand to ensure a secure, comfortable fit even while you are riding.
