GIRO Time Trial Helmet Aerohead Mips Matte Black M size 55-59cm * JCF seal not included due to purchase from overseas通販. Purchased new. Used distance: Approximately 150km Selling because I purchased another helmet. Used 3 times in training, but no drops or crashes. I took good care of it, so the condition is quite good. - Brand: GIRO - Color: Matte Black / Titanium - Type: Triathlon/TT helmet - Features: Aerodynamic design Specs ・Polycarbonate shell ・Super Fit™ Engineering ・ZEISS® Optics eye shield ・Magnetic anchor attachment ・X-Static® hydrophilic anti-bacterial pads Weight 450g (M size reference value) The fit of the AEROHEAD ULTIMATE MIPS is the "Global Fit," a world standard. It differs from the shape that many Japanese people find easy to wear (AF Asian Fit = not very long front to back, but wide and deep). It fits many people when considering the head shape standards of global races (oval), but Japanese people may find the width a bit narrow. If your head circumference is around the border of the two sizes, I recommend the larger size. Wind Tunnel™ ventilation and internal groove structure keep your head cool, allowing you to focus on and compete in heated races. The AEROHEAD™ MIPS is equipped with a unique eye shield that wraps around the eyes, providing excellent visibility and clarity. The magnetic anchor attachment securely fixes the eye shield to the helmet's shape with six magnets, and when you get off your bike, you can remove it, flip it over, and easily hold it on top of the helmet. Equipped with the MIPS system, it changes the direction of rotational impact energy from multiple directions during a fall, providing even greater safety and protection against specific impacts. #GIRO #Roadbike #TT #Triathlon #AERO
