As mountain bikes get ever more capable across ever more technical terrain and trails deliver more progressive features and challenges, your riding skills will be pushed ever further too. And when you come up short and come down hard, the Tyrant Spherical Helmet (MIPS) provides incredible all-over head protection. The first line in head-defense comes via the innovative Spherical Technology powered by MIPS®.
Spherical Technology powered by MIPS® (Multi-Directional Impact Protection System)
As you'd expect, all Giro helmets are designed to not only meet but also exceed stringent safety standards. The ball and socket Spherical Technology, powered by MIPS, allows the outer liner to rotate around the inner liner during a crash, ensuring you enjoy an extra level of brain-protecting technology, designed to redirect energy and provide more protection in certain impacts.
This system also eliminates contact of plastic and slip planes with your skin, boosting your overall mountain bike riding comfort.
Protection is further enhanced with the Hardbody™ Shell. This tough outer wraps from the outside of the helmet to the inside, giving a significant boost to durability compared to regular helmets. The in-mold construction sees a tough polycarbonate outer shell fuzed directly with the helmet’s impact-absorbing foam liner. This in-mold fusion process allows Giro to optimize ventilation without compromising protection, so in-mold helmets can be both lighter and cooler than traditional helmets.
Progressive layering of the core also improves energy management across both slow and high-speed impacts. EPS foam takes care of high-speed impacts. EPP foam meanwhile, has rebound characteristics best suited to more common slow-speed impacts.
Mountain biking soon builds up a sweat. But thanks to the 14 Wind Tunnel vents, with cheek pad ventilation, fresh cool air is allowed to circulate. Cool air rushes in and warm stale air is pushed out, offering greater moisture control and comfort.
Giro also gives the Tyrant their Channeled Stack™ ventilation at the brow. This draws warm air away from your goggles, leaving your vision clear and fog-free - quick lines will never have been easier to see.
Roc Loc® Air DH Fit System
The Tyrant MTB helmet uses the Roc Loc® Air DH fit system, allowing you to get a secure and precise fit every time you jump on your bike. It also features a bumper around the dial to prevent accidental adjustments if your helmet contacts your backpack or neck brace, ensuring your helmet always remains where it should.
