Giro Aerohead Mips Aero/Tri Cycling Helmet

Product Information

The POC offers a large field of vision, especially above the brow. Those riding with a super low position will like this, but anyone trying to get aero can appreciate an unobstructed view. The new Aerohead actually comprises two slightly different variants — the Aerohead MIPS and the Aerohead Ultimate MIPS — both with a new streamlined shape that Giro says will save its wearer up to four seconds over a 40km-long time trial relative to its already-fast Selector, and up to 20 seconds over a 180km-long Ironman leg. Derived from Specialized's previous S-Works McLaren TT helmet, the newer S-Works TT is updated with patented side 'gill' vents that increase airflow through the helmet. Having never tried the McLaren, I can't comment on any improvement in cooling, but the S-Works TT is reasonably well-ventilated for a time-trial lid. The Giant is fairly tight over the ears – likely a good thing in terms of aerodynamics – but can be a bit uncomfortable on longer rides. Personally, I think the Rivet TT would be great for short, hot time-trials or triathlons.

and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® 5 This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort For those who are a bit less statuesque or prefer a more head-up position, something with a snub tail or bobtail shape will likely yield the best results. What do I need to know about ventilation in a time trial helmet? Reduced weight and aerodynamics aren't the only design details to take into account when considering this helmet. With increased ventilation comparable to the higher-end model, the Aerohead MIPS TT helmet provides four Wind Tunnel vents that work homogeneously with internal channelling and the vented lens shield to provide a constant flow of cooling air. Proven to boost airflow without affecting aerodynamics, this system provides superior ventilation for when the heat starts to build up.Certification:• Complies with the US CPSC safety standard for bicycle helmet for persons age 5 and older POC's Cerebel is a huge departure from the company's first go at a time-trial helmet, the Tempor. Not only is it much smaller, it's also derived from an entirely different design philosophy. On hot days it is very nice if a bicycle helmet doesn't get too hot. To cater to this, the Aerohead MIPS is equipped with 4 Wind Tunnel vents and internal channelisation. The cooling airflow enters through openings at the front. The cool air is then guided through the ducts to the ventilation ports. In short, you won't get overheated. custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand. Super Fit™ Engineering Giro's Aerohead MIPS is unique in many ways. First of all, it's the only helmet here with a MIPS rotational impact liner. The Aerohead also has a forward-overhanging shape that Giro claims is fast over a spectrum of head positions. It certainly extends further over its wearer's brow.

Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines Lazer's Wasp Air Tri is something of ashape shifter. While designed to be fast, it also puts an emphasis on ventilation. With an optional longer tail and several different venting options, it's widely adaptable for changing conditions and different rider needs. While this is something that can be worn during a race, it's also a great training tool. As mentioned above, Lazer also offers an optional longer tail section for riders who like an elongated helmet profile. Ventilation is a tough one when it comes to time trials because the more closed off helmets are usually faster in the wind tunnel; however, if you overheat during your event, your body will hit the brakes on your max output.

While fast, the Aerohead has its foibles. The visor's optics are decent, but not as good as the POC or Specialized. Perhaps the most straightforward of the helmets in this line-up, the Giant has a clear pedigree thanks to Tom Dumoulin, Ellen van Dijk and their Sunweb teammates. There is no visor on offer and no shape-shifting tail section. But what you do get is a very fast helmet designed for a wide variety of rider positions.

The wraparound visor covers more of the face and this probably adds to the sensation of an already hot head. Additionally, the Aerohead isn't the coolest helmet in the lineup.

The ventilated visor and the gills at the side do a good job of moving air through the helmet. That said, depending on the tilt of your head, it's easy to experience noise. When I dropped my head, looking down, it would whistle at me. While annoying at first, it came as a handy reminder to keep my head up, looking forward.Breathable and lightweight, the Giro Aerohead MIPS TT Helmet is an excellent choice for the rider wanting aerodynamic gains. With a drag-reducing design, style and shaping inherited from its leading-edge Ultimate sibling model, this helmet features increased ventilation to keep triathletes and time trialists cool when the heat is on. By utilising an in-mould weight-saving process that fuses a polycarbonate shell to the EPS foam lining, Giro has developed a design set to smash time trial events. With a smooth outer shell that effectively reduces air drag, this incredibly sleek aerodynamic helmet has been built so you can go faster than before, setting record speeds. lens in the "flipped up" position - perfect for fast swim-to-bike transitions. Features Hardshell With In-Mold hardbody™ Lower Wrap The Wasp’s visor aids in ventilation as well. It can be, using different indents in the mounting hardware, pulled away from the helmet to increase ventilation and doing so works exceptionally well. If you prefer to run sunglasses in lieu of a visor and if staying cool is a constant struggle, the Rivet TT is the way to go. Giro Aerohead MIPS
