The Rootage Helmet The ALPINA ROOTAGE is one of the safest bike helmets manufactured by Alpina. The outer shell of the helmet has integrated highperformance carbon panels which make the ALPINA ROOTAGE both extremely robust and also light. At the same time, polycarbonate inserts stiffen the large air vents and thus, in combination with the internal ventilation channels, guarantee optimal air conditioning inside the helmet. The hard shell of the helmet has a soft COOLMAX™ core. Antibacterial pads ensure maximum comfort. The edges of the helmet are finished with Edge Protect. A large peak ensures even better visibility. A further feature is the high-quality Run System Ergo Flex for adjusting the helmet‘s height – an additional bonus in respect of comfort and safety. Note: Please measure the head circumference to get the right helmet size. Alpina Rootage technologies: HI-EPS Alpina helmets have inner shells made of Hi-EPS (highly expanded polystyrene). This material consists of many microscopically small air chambers which effectively absorb the forces caused by an impact. Hi-EPS provides optimum protection with the benefit of allowing extra-thin walls. CERAMIC This impact- and scratch-resistant polycarbonate shell is fitted to all Alpina helmets manufactured using the Inmold procedure. The blank workpieces are shaped at high temperature onto the form of the helmet design and the shells are then pressed onto the helmet's Hi-EPS body. The material combines a number of distinct advantages: it is impact- and scratch-resistant, it contains UV stabilisers and is anti-static. INMOLD TEC The Inmold production process involves the polycarbonate outer shell of the helmet being heated to a high temperature and "baked" onto the EPS helmet body at high pressure. This produces a permanent bond across the entire surface of the inner and outer shells, producing a helmet with the advantage of being very light yet extremely stable. EDGE PROTECT This manufacturing process ensures that there are no sharp edges to be found on Inmold helmets, reducing the risk of getting hurt in two ways: firstly, handling the helmet is always comfortable on the hands, and secondly, the bottom edge of the helmet will not cause scratches to the neck and shoulder areas in the event of a crash. CARBON TEC For the best possible protection choose Carbon Tec. This helmet incorporates carbon in the Inmold process, a highly efficient material which produces a helmet that is tough yet lightweight. Integrated carbon-fibre plates in the outer shell make the ALPINA ROOTAGE even more resilient and light. Any impact force at a given point on the helmet is reduced as it is absorbed by the carbon-fibre and distributed across a wider area. RUN SYSTEM ERGO FLEX Run System Ergo Flex is the lightest and most comfortable adjustment system from Alpina. Its sophisticated construction ensures an even fit around the head to provide enhanced protection. Run System Ergo Flex features a finely tuned adjustment wheel – the ultimate in easy customisation for a comfortable, tailored fit. FLY NET: The front ventilation holes have a mesh lining which effectively works as an insect screen to protect the wearer's head from insect bites when riding in hot or humid conditions. Y-CLIP: A helmet can only provide proper protection if it stays securely in place in the event of an impact. The fastening that joins the two straps under the ear is critical to this. Alpina's Y-Clip system guarantees a perfect fit down to the last millimetre, all in a matter of seconds. ERGOMATIC Tried and tested countless times, this is the buckle used in all Alpina cycle helmets. It features a red push button and multi-step automatic adjustment. It can be used one-handed, so for example you can loosen the strap when riding uphill and tighten it again for the descent, and it cannot come open in the event of a crash. The Twist Five QVM+ glasses match this helmet perfectly. Weight supplement: Manufacturer's Spec
