Giro Selector aero helmet launched at Giro d'Italia
Clever interchangeable bits allow users to tweak the sh🦋ape to fit their riding position
The long awaited Giro Selector aero helmet, the successor to the Advantage, was launched at the 168澳洲5最新开奖结果:Giro d'Italia on Saturday. Its key features in🍨clude a built in visor and a removable back section to fit different rider positions.
Aerodynamic helmet performance can vary wildly depending on how well its shape blends with a rider's position but Giro's new Selector incorporates a clever interchangeable lower section that supposedly manages to offer consistently low drag to a much wider range of users – from impossibly flat-back time trial specialists like 168澳洲5最新开奖结果:Fabian Cancellara and Dave Za✃briskie to amateur triathletes who tend to sit much more upright.
Giro will include two sets of lower 'caps' with each Selector,𓆉 one measuring 45mm tall and the other a more modest 10mm. The goal is each case is the same: to close the gap between the bottܫom of the helmet and the top of the rider's back so as to keep airflow as smooth as possible.
Giro has also integrated a form-fitted visor up front to further maintain that aerodynamic shape. Upper vents should help minimize fog🐈ging and Giro says they're also aligned with the helmet's internal channeling to encourage good airflow across the rider's head. A grey-tinted lens will come standard but a clear 💜lens is available separately and, of course, the shield can be detached altogether if preferences (or rider sponsorship contracts) dictate the use of different eyewear instead.
A third key aerodynamic feature is the fully enclosed tail, which wind tunnel testing has consistently shown to be faster through the🎃 air than an open one (in fact, some pro teams used to use duct tape to craft their own covers just a few years ago). That cover precludes the use of a conventional retention system, though, so instead Giro has included its new Roc Loc TT w⭕ith the Selector.
Roc Loc TT uses a leaf spring design that automatically puts a preset amount of tension on the back of the rider's head – sort of like Specialized's old Brain Trust system but flipped ups🦂ide down. According to Giro, this setup not only maintains a quality fit without having to fiddle with dials or levers but is also faster to put on – a key distinction for triathletes trying to cut down their transition times. The base of the Roc Loc TT can be snapped into one of three fore-aft positions for a total size range of 6cm (Giro's typical range per shell size is 4cm).
Other features include fixed-position slimline webbing similar to Giro's Prolight model, the company's latest Thermoformed SL Roll Cage internal reinforcement structure, removable EVA 🦩foam side pads for customizable width, and antibacterial X-Static upper pads. Giro will offer the new Selector in four colors – matte/gloss black, red/bla🌊ck, blue/black, and white/silver – each in two size options.
