Giro is promising a more dialed-in fit system and lighter weight in its helmets sporting the new Roc Loc 5 fit system.
At the moment, Singletrack.com is waiting on a Roc Loc 5-outfitted lid or two to arrive, after which we’ll strap ‘em on and then give you our take. True, we haven’t worn one of Giro’s Roc Loc 5 helmets yet, but the latest offering looks promising, especially if you’ve cursed a helmet for its limited range of adustability.
Giro says the Roc Loc 5 system will be available Aug. 1 on the company’s six leading helmet models, including the MTB lids Athlon and Hex. The key feature of the fit system is a ratcheting, micro-adjustable dial that can be turned with two fingers while a helmet is on a rider’s head. Audible clicks tell the rider the Roc Loc 5 is being tightened or loosened.
Another part of the Roc Loc 5 is a low-profile “Vertical Fit” tab that allows for up to 15mm of up-and-down adjustment. By clicking the Roc Loc 5’s Vertical Fit tab into any of three positions, a rider can fine-tune the height of the Roc Loc 5’s “Dual Pods,” which Giro says are “soft, ergonomic polygons that gently cradle the rider’s occipital lobe.”
“Take a Roc Loc 5 equipped helmet out of the box, drop it on your head, turn the dial to adjust tension and you’re good to go,” said Giro’s Brand Manager Dain Zaffke. “It is the best fitting, most secure and lightest fully featured fit system available for on or off-road riding.”
All that and 40 percent lighter when compared to its predecessor, Giro claims.
Along with the off-road Athlon and Hex helmets, the Roc Loc 5 is featured on the Ionos, Atmos, Advantage 2 and Saros models.
If you’ve been watching the Tour de France, you’ve already seen helmets outfitted with the Roc Loc 5 on Team RadioShack, Astana, Garmin-Transitions and Rabobank. And speaking of Rabobank, American mountain biker Adam Craig (Rabobank-Giant) is racing a Roc Loc 5 equipped lid.
