A TAILORED APPROACH TO AERODYNAMICS.
The foundation of aerodynamics is pure and unyielding; every gram of drag
devours time and calories. And as the speed increases, so does the air’s
appetite. Instead of simply facing this challenge head-on, the Giro Selector
Time Trail Helmet gives you a new edge in the race of truth – the tail. By
combining a smooth front profile with either of two different lower tails, the
rider can optimize the helmet for best aerodynamics based on their anatomy,
riding position and even course conditions. The result is a helmet that works
for you like no other helmet can when every split-second counts.
– The In-mold construction process permanently fuses a light-yet-durable outer
shell with the helmet’s impact-absorbing EPS foam liner, enhancing the strength
of both parts, This fusion process reinforces areas around vents and ribs,
creating a one-piece ‘exoskeleton’ that allows the helmet to be lighter, more
durable, and better ventilated than helmets with shells that are fastened or
adhered to the liner.
Super Fit Engineering
– Giro’s proprietary Super Fit sizing system is based on “human scale factors”
data and over 20 years of hand-crafting helmets to fit the best bike riders in
the world. By creating helmets in 3 sizes to fit snugly and securely while also
matching the human body’s form, Giro’s Super Fit sizes comfortably fit up to 98%
of the world’s population, yet look (and fit) like they are custom made just for
Roc Loc TT Fit System
– When every second counts, Roc Loc TT system offers a faster fit to speed you
through transitions. The set-and-forget positioning feature creates a
self-adjusting fit with secure feel, and helps to improve aerodynamics by
allowing the back of the helmet to be closed off to the wind. So you go faster
without any hassles or compromises.
– X-Static padding contains a fiber made with layers of pure silver that is
permanently bonded to the surface of the fabric. Silver has 100% natural
anti-microbial performance that helps to reduce odor and regulate heat, so your
helmet stays fresh and comfortable naturally.
