The WingBack emphasises its sporty character with deep ventilation channels, thin struts and a separation edge at the rear.

SAFETY ON STEEP TRAILS Steep climbs, high-speed racing, all-day adventures: "Down-country" is action-packed, which means the demands on equipment also increase. Down-country is all about going up fast, down fast and repeating. The Moventor 2.0 MIPS is virtually perfectly for the demands of mountain bikers. The MTB helmet is lightweight, well ventilated and has a deeper fit that gives more protection at the back of the head. When the trail points downwards, the ten air inlets and nine air outlets provide good ventilation. In addition to all the well thought-out features for off-road use, the MIPS model has impact protection. This is intended to protect the brain, especially if the cyclist's head hits the ground at an angle during a fall. In a fall, the brain is exposed to strong rotational movements that can lead to severe brain injuries. With MIPS, a movable low-friction plastic shell is integrated into the helmet to ensure that rotation is reduced and the head is better protected. - Multi-Shell In-Mould for a permanent bond between the outer shell and the shock-absorbing helmet material (EPS) - Zoom Ace MTB: Height-adjustable adjustment system to fit the head circumference - Ponytail compatibility: Helmet well suited for ponytail wearers - Laterally adjustable, non-slip TriVider strap system - Moulded lower shell for added durability - QUIN ready—easy upgrade with the separately available QUIN chip for fall detection - MIPS: Impact protection that protects the brain, especially when the cyclist's head hits the ground at an angle during a fall. - GoggFit: Device that allows a pair of goggles to be fixed to the helmet when the athlete doesn't need them while riding - Ventilation: excellent ventilation through 10 air inlets and 9 air outlets

FOR DEMANDING TRAILS The CliffHanger is the flagship trail model in the ABUS MTB series. When you're riding up and down steep hills on an enduro bike, the MTB helmet offers reliable protection. Lighter, better ventilated and with an adjustable TriVider webbing spreader—the CliffHanger scores with these features. The special MTB adjustment system also ensures that the helmet sits comfortably and firmly on the head when rattling through the wildest of rock gardens. The inner shell made of EPS hard foam is foamed into a three-part outer shell, making a lightweight and sturdy helmet. The existing Multi-directional Impact Protection System (MIPS) can reduce energy by up to 40 percent in the event of an oblique impact. With the CliffHanger, we have succeeded in developing a helmet that offers virtually perfect conditions for high speeds and demanding trails. - Multi-Shell In-Mould for a permanent bond between the outer shell and the shock-absorbing helmet material (EPS) - Zoom Ace MTB: Height-adjustable adjustment system to fit the head circumference - Ponytail compatibility: Helmet well suited for ponytail wearers - Laterally adjustable, non-slip TriVider strap system - QUIN ready—easy upgrade with the separately available QUIN chip for fall detection - MIPS: Impact protection that protects the brain, especially when the cyclist's head hits the ground at an angle during a fall. - ActiCage: Structural reinforcement integrated in the EPS to optimise stability - Moulded lower shell for added durability - Height-adjustable visor - GoggFit: Device that allows a pair of goggles to be fixed to the helmet when the athlete doesn't need them while riding - Ventilation: excellent ventilation through 8 air inlets and 6 air outlets - FidLock magnetic buckle

Make sure you have the decisive edge in the battle for every watt: take your racing experience to the next level with the GameChanger 2.0 MIPS.

The AeroBlade optimises the airflow with a special grid structure and adapts to different speeds, side angles and helmet inclinations. So the GameChanger 2.0 has a solution for every racing situation. Even on the hottest rides, you can keep a cool head thanks to the AirBoost air inlet and sophisticated ventilation system. But so that comfort doesn’t fall by the wayside, you can conveniently adapt the helmet fit using our patented adjustment system. ActiCage increases the stability of the road helmet.
