Carnac Notus 2 Road Helmet




Size guide

Helmet Sizing

Measure around your head at the widest point to determine the size you need.

Size guidance: To help choose the correct size helmet for your head measure around the widest part of your head, about an inch above your ears, with a soft tape measure, or piece of string. If you are on the cusp between sizes we advise that you size up.

We've taken our best-selling Carnac Notus cycling helmet and made it even better. Our 10/10 Gold Award winning road helmet is now smoother, sleeker and cooler than ever. With revised venting we've reduced drag, improved cooling and kept the protection you've come to trust.

Carnac's Notus 2 Road Helmet mixes striking industrial design with sleek aerodynamics. The Notus 2 uses four massive rear facing vents and additional temple venting to offer maximum cooling while still offering maximum protection.  

A correctly adjusted chinstrap is an integral part of the safety provided by any cycling helmet. If your chin strap isn’t correctly tensioned there is a risk that the strap may pull through the buckle. Always make sure that the chin strap is adequately cinched up every time you put your helmet on. A loose chin strap potentially reduces the effectiveness of your helmet.  

The Carnac Notus 2 is all set to repeat the success of the original model. Grab one while you can.
