Casco SPEEDtime TT helmet
Aero triathlon/time-trial helmet with 18 vents and no tail
Casco already have fine form with their SPEEDseries helmet range, scooping Olympic medals on both the track and road. The SPEEDtime is their triathlon/time-trial lid, and continues the trend of aerodynamic helmets lacking an elongated tail.
Design tech includes 18 vents, a removable front opening, a double shell construction and patented air guidelines on the outer shell of the helmet that seek to optimise the air stream.
The £349.99 helmet comes with or without drawn-out reflective lenses, aimed at maximising aerodynamics and providing an interference-free field of vision. We’ll be testing this soon.
