ROAD RACING BIKE HELMET: The Bullet 2.0 helmet provides an answer to the age-old dilemma of ventilation versus aerodynamics. The outer-shell features 8 airflow vents and the Airslide system to keep you cool. This bike helmet weighs 315g and is CPSC certified.
AERODYNAMIC CONSTRUCTION: The protective outer shell features a narrow shape and closed-shell creating an aerodynamic road helmet. This helmet features the LAZER Venturi Cap which uses Venturi technology to accelerate the airflow through the helmet.
STAY COOL WITH THE AIRSLIDE SHELL: The outer shell Airslide system of the helmet can open in the front of the helmet to create an airflow throughout with exhaust vents at the rear. When aerodynamics are more important than ventilation, the entire Airslide system can be exchanged for a fully closed cap, creating a more aerodynamic version of the helmet.
MAGNETIC PANORAMIC LENS: The cycling helmet is designed with a panoramic lens to protect your eyes and face from wind and debris. When not in use, the lens magnetically secures to the helmet.
SAFETY FEATURES: Keep drivers aware of your presence with this safety helmet. This helmet comes equipped with a rear safety light as well as reflective stickers for increased visibility at night.

FUSION IN-MOLD POLYCARBONATE SHELL & PROGRESSIVE LAYERING CONSTRUCTION - A process pioneered by bell bonds the helmet's outer shell to the eps foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable eps foam densities to better manage the transfer of energies after some impacts
FLOAT FIT RACE (INTEGRATED WITH MIPS) & MIPS-EQUIPPED - Custom fit at the highest performance, Seemlessly integrated with MIPS and offers three-way adjustability: height, pad width and tension. MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts
X-STATIC AND XT2 PADDING & SWEAT GUIDE - Quick-drying materials, woven with real silver fibers, inhibit growth of odor-causing bacteria and fungi. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear
NO-TWIST TRI-GLIDES & PROGRESSIVE LAYERING - Quick-adjust fasteners that help keep straps flat and properly positioned. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts.
SPECIFICATIONS - Small (52-56 cm), Medium (55-59 cm), and Large (58-62 cm) Sizes; Overbrow Ventilation System with 18 vents; CPSC Bicycle Certification

LIGHTWEIGHT INTERNAL POLYCARBONATE ROLL CAGE FUSION, & IN-MOLD POLYCARBONATE SHELL - A process pioneered by bell bonds the helmet's outer shell to the eps foam liner to create a sturdier helmet
MIPS-EQUIPPED - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts
FLOAT FIT & NO-TWIST TRI-GLIDES - A minimalist, lightweight fit system with an easy-to-turn rubber over-molded dial for adjustments (integrated with MIPS). Quick-adjust fasteners that help keep straps flat and properly positioned
SWEAT GUIDE & OVERBROW VENTILATION - Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear. Overbrow Ventilation features intake ports on the brow of the helmet to usher in cool air and push it through the air-channel matrix for full-head ventilation
SPECIFICATIONS - Small (52-56 cm), Medium (55-59 cm), and Large (58-62 cm) Sizes; 18 vents; CPSC Bicycle Certification
