Kask Protone Icon Cycling Helmet

Kask Protone Icon Road Cycling Helmet

The elements are in perfect equilibrium: performance, aerodynamics and safety. The design leaves you in no doubt: The Kask Protone Icon is KASK's new classic, an exceptional helmet for road, gravel, cyclocross and MTB cross-country. Every aspect has been redesigned to push performance to the limits.

Kask has always been committed to creating products that provide both excellent safety and comfort, exceeding requirements set by international standards and norms.

Kask WG11 test is an internal protocol adopted by Kask to identify an objective method, based on scientific sources, for measuring the performance of its helmets against rotational impacts.

Most helmets tests use rotational impact prevention technologies with headforms that have a higher coefficient of friction than those of the human skull and therefore may not reflect what occurs in some accidents.

The "pass-fail" criterion is based on the BrIC value, an algorithm that defines the level of brain injury.This value must be lower than 0,68.

The final test protocol is:

OBLIQUE IMPACT TESTs
oblique tests @ 45°, impact speed 6 m/s, BrIC < 0,68
+ grade 80 closed-coat aluminum oxide abrasive paper
+ headform nominal coefficient of friction 0,3
+ wireless system: triaxial accelerometer + n. 3 ARS
Headform: EN960 serie
Measurements:
Peak of rotational acceleration, Peak of linear acceleration, HIC, BRIC (< 0,68)

All KASK helmets successfully pass this test, with values that are substantially less than 0,68 BrIC 0,390
