WaveCel: the biggest advancement in the protection against cycling concussions

Trek and Bontrager have partnered with WaveCel to create a helmet technology that disrupts 30 years of accepted safety standards. You only get one brain. It's worth protecting.

What is WaveCel?

WaveCel is a revolutionary, Bontrager-exclusive helmet technology that's up to 48x more effective than standard foam helmets in preventing concussions. *

* Results based on AIS 2 Injury (BriC) at 6.2 m/s test at 45° comparing a standard EPS Helmet and the same helmet modified with WaveCel insert as described in detail in Evaluation of a Novel Bicycle Helmet Concept in Oblique Impact Testing. This study compares standard foam helmets and the same helmets with WaveCel inserts in a simulation of a typical bike crash.

WaveCel is a collapsible cellular structure that lines the inside of your helmet.

It works like a crumple zone that absorbs the force of an impact before it reaches your head.

Nearly 99 out of 100 times, WaveCel can help prevent concussions. Standard foam helmets? Not so much.

Superior protection. Proven.

Bontrager WaveCel helmets offer significantly better protection than standard foam helmets. They're up to 48x more effective in preventing concussions caused by common cycling accidents. *


Cool and comfortable

The best helmet is one that doesn't distract you when you're riding. WaveCel helmets are extensively tested in the wind tunnel for air flow.

Nothing outweighs safety

Gram for gram, WaveCel punches way above its weight when it comes to protection. This revolutionary safety tech adds only 53g on average to Bontrager helmets.

Dial your fit

WaveCel helmets are engineered to fit and feel great. They're easy to adjust with a single Boa dial and the included fit pads, and every one has a uniform dome shape developed from over 150 studies on what feels best in helmets.


If your WaveCel helmet is impacted within the first year of ownership, we'll replace it for free through the Bontrager Crash Replacement Guarantee.


WaveCel is available exclusively on Bontrager helmets online and through authorised Trek and Bontrager retailers.


Every Bontrager WaveCel helmet received a five-star rating in Virginia Tech’s safety rating system. That’s perfect marks on every helmet in the line-up.
