Product description

Syntax is a racing helmet packed with technology. With its aerodynamic shape and perfect ventilation, it won't get lost on flat or hilly terrain - just the perfect all-rounder.
Moreover, thanks to the Roc Loc clamping system, which also integrates a MIPS slip layer in the case of the MIPS variant, it fits luxuriously on the head.
The helmet has 25 vents and a Wind Tunnel for perfect ventilation. Antibacterial CooFit linings and ultra-light Slimline straps ensure maximum comfort during the ride.

MIPS (Multi-Directional Impact Protection System) provides increased protection against rotational forces on the head.

Technology

  • ROC LOC® AIR A revolutionary clamping system that improves both fit and ventilation of the helmet. The clamping system creates a small space between the head and the helmet itself where cool air flows. The setting options are the same as for the Roc Loc® 5 system.

  • IN-MOLD® Designation of a technological process in which EPS polystyrene foam is pressure-injected into the shell and reinforcements enclosed in the mould. Their connection reinforces the area of the vents and ribs. The result is a compact, uniform, lightweight, safe and very durable helmet.

  • MIPS (Multidirectional Impact Protection System) is a slippery insert between the EPS shell (helmet body) and the inner liners. In the event of an angled impact (for example, if you catch your head on a branch), the helmet's EPS shell will roll a few millimeters over the MIPS layer, protecting your head and brain from the violent rotational jerk.

  • The SUPER FIT™ System is made up of up to four helmet sizes designed to cover a range of different head sizes for all users. Thanks to this system, the helmets of the higher categories are ideally prepared for every rider.
