Specialized Evade 3

It ranks #2 (A tier) on our consolidated bike helmets board, drawn from 19 cited sources across 18 outlets.

Road riders and racers who want an aero helmet without giving up protection. It sits at number two in A tier on our bike helmets board, with reviewers noting excellent aerodynamics, a lightweight shell and strong impact protection, and an engineering analysis citing it as an example of modern helmet design. If you care more about ventilation than aero, the Trek Velocis MIPS is the top pick. If you want an all-round road helmet without the aero shape, the Giro Synthe MIPS is the other A tier option. Trail riders should look at the Bell Super 2 instead.

Yes. Excellent aerodynamics is one of its strongest findings in our research, which is why it suits racing, time trials and fast group rides. Aero road helmets trade some open venting for a smoother shell, so expect it to feel warmer than a fully vented helmet on slow climbs.

Our research records strong impact protection and modern EPS foam usage, and an engineering analysis held it up as an example of contemporary safety design. Like every helmet on our board it carries a cycling safety certification. Replace it after any crash that hits the head, because EPS foam protects once.

Aero helmets have fewer and smaller vents than open road helmets, so the Specialized Evade 3 will run warmer at low speed than a vented design such as the Trek Velocis MIPS. At speed the airflow through the channels keeps most riders comfortable. If you mostly climb slowly in heat, pick the vented helmet.

Measure your head circumference just above the ears and choose the size whose range covers it. The helmet should sit level, a finger width above the eyebrows, with no rocking before the strap is fastened. Snug the rear dial and set the straps in a V under each ear with one finger of slack at the chin. Aero shells reward a close fit because a gap at the front disturbs the airflow.
