Features:

• Roc Loc Sport Fit System: The Roc Loc Sport Mips 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 to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport Mips fit system brings premium function to sport-level helmets.

• Hardshell With In-Mold Hardbody Lower Wrap: The two‐piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

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.
