Bontrager Circuit WaveCel Helmet

If you’re going to get just one helmet, make it this one

Built for you, no matter where you roll. The Circuit is a versatility-focused helmet ready to tackle every ride, from trail to tarmac, bike path to bike park. Bontrager designed the Circuit with a streamlined profile that not only delivers a sleek aesthetic, but also improves aerodynamics - all the while dropping weight. The result? A helmet that’s ready to race your local crit on Saturday and head to the singletrack for cross-county laps on Sunday.

What is WaveCel?

WaveCel is a collapsible cellular structure that lines the inside of your Bontrager helmet. It’s designed to be more effective than traditional foam helmets in protecting your head from injuries caused by certain cycling accidents.

It works like a crumple zone that helps absorb the force of an impact before it reaches your head. In order to protect your head and absorb the energy created by an angled impact, WaveCel is designed to go through a three-step change in material.

Flex

First, the cells flex to reduce initial frictional forces.

Crumple

Next, the cells crumple like a car bumper on impact.

Glide

Finally, WaveCel glides to redirect energy away from your head.

See, be seen, and get the footage

Blendr’s seamlessly integrated front and rear facing magnetic mounts offer a perch for your GoPro and Bontrager Daytime Running Lights so you can see, be seen, and check the footage after your ride. The magnetic connection makes light installation simple, stays secure through rough and fast riding, and is tested for breakaway forces to make sure accessories detach in the event of a crash.

Faster shapes, better rides

When it comes to design, Bontrager throws it all on the table. They put together the brightest minds to optimize engineering and study CFD analysis of airflow over time so they can understand the velocity and trajectory of air particles in the wake of the helmet surface. That’s a whole lot of words to say: they find the shapes that help every rider go faster and feel smoother on the bike.

Comfort on every ride

Protection is a priority, but it won’t get you very far without comfort. Bontrager pours hours of research into developing the best features that elevate fit, stay secure, and feel great for every rider on every ride.

Dial in comfort

Micro-adjustable BOA® Fit System allows you to fine-tune your perfect fit.

Flat fit straps

Comfortable, lightweight FlatStrap semi-fixed dividers fit flat to your face on a single strap. They move fore and aft with plenty of adjustability, allowing you to achieve an ideal position under your chin for a fit that’s as comfortable as it is secure.

Soft and fresh

Moisture-wicking pads elevate comfort while pulling away perspiration on hot rides and when you’re putting in major efforts. At the end of the day, the pads are easy to remove for washing, so you stay fresh ride after ride.

Fit for everyone

To get the most out of your protection, your helmet has to fit right. We offer a huge size range to fit any rider, and premium micro-adjustable BOA® Fit Systems that allow you to fine-tune comfort for a secure hold while you ride.
