GIRO TECHNOLOGY.
Roc Loc 5. After more than two-years of development, Giro introduces Roc Loc 5.
This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb.
Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.
Roc Loc SL. Minimal, simple, incredibly comfortable. With one quick adjustment of the webbing system, Giro's new Roc Loc SL self-adjusts to provide a comfortable, secure fit. They’ve also spec’d supple, Italian-made, featherweight webbing material for maximum comfort. Roc Loc SL is found exclusively in Giro's new Prolight race helmet.
Acu Dial 2. Giro's Acu Dial 2 fit system offers the convenience of single-handed adjustment, plus variable-fit belt anchor points providing a brilliant fit and feel. Acu Dial 2 is slim, durable, and even ponytail-compatible.
Acu Dial. The Acu Dial system combines single-handed adjustment with a full fit band that brings a quick, sure ponytail-compatible fit in Giro's line of Universal Fit helmets.
One-Step. Giro’s new OneStep self-adjusting fit system takes the hassle out of fitting kids’ helmets. It’s the fastest and most intuitive way to properly fit a child’s helmet. Just put the helmet on, close the PinchGuard buckle and off they go. They’ve also included LED taillights for added visibility.
In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
Giro's In-mold composite Sub-frame is a composite skeleton fused into a helmet’s EPS liner. Visible on the bridges between vents, this series of composite plates is directionally “tuned” to provide structural support, impact dispersion and penetration resistance. I.C.S technology is what allows Giro to carve those massive vents— as seen in their Ionos helmet, for example—without compromising rider protection.
P.O.V. Visor. Point Of View visors are anchored by a patented internal clutch mechanism that allows 15-degrees of tool-free, on-the-fly vertical adjustment while preventing the visor from rattling and coming loose over rough and technical terrain.
Wind Tunnel-ventilation. Giro helmets are developed utilizing their proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.
Roll Cage reinforcement is a tough web of DuPont Nylon molded inside a helmet’s EPS foam liner. It provides an extra measure of strength and integrity that you’ll never notice…unless you need it.
Universal Fit. Giro's Universal Fit family of helmets is sculpted to look good and fit great for most people on the first try. By developing unique shell sizes based on select customer groups and combining them with an adjustable fit system, Universal Fit helmets make it easier for you get the right fit, right out of the box, right away.
Super Fit Engineering. A great helmet is so comfortable that once it’s on, it virtually disappears. Giro's proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury™, a helmet that fits 98% of the world’s population, yet looks (and fits) like it was custom made just for you.
