Universal Fit™ Sizing
Our Universal Fit helmets are sculpted to look good and fit great for almost anyone on the first try. By developing proprietary shell sizes based on specific customer groups, and combining them with an easily adjustable fit system, it's easy for you get the right fit straight out of the box, without the hassle or expense of trying multiple sizes.

In-Mold Construction
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.

Roc Loc® Sport Fit System
The Roc Loc® Sport fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar Roc Loc® 5 and ponytail compatibility, the new Roc Loc® Sport fit system brings premium function to sport level helmets. Versions with the Integrated Mips® Brain Protection System may provide an additional measure of protective capability in certain impacts.

Bike Helmet Size Guide
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

FOR HELMETS EQUIPPED WITH MIPS TECHNOLOGY, PLEASE REVIEW THE FOLLOWING WARNING: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD.
