Rudy Project Spectrum Helmet

With a semi-aero, yet well ventilated design, the Rudy Project Spectrum was built for road use, and is most effectively worn in a moderate to aggressive riding position. Shaped for performance, the Spectrum is designed to outclass road helmet standards of comfort, protection and weight. The Spectrum revolutionary dynamic design features a seamless integration of three InMold EPS liners knitted together. This unique structure boost ventilation while keeping this race machine extremely lightweight and comfortable.

The style and design of the Spectrum is striking, in an attractive way that many aero road helmets just can't attain. The shape and structure are fully interactive, with the vents both channeling air and allowing it to slip up and over the top. The engineers give strict attention the idealized angle that the rider carries their head at, to create the most aero opportunity while riding. As most riders who choose aero road helmets are accomplished riders or racers that can maintain an aggressive postures, the Spectrum is designed to maximize that body and head angle. If you are sitting up too high, the Spectrum will still look good, but be less effective in reducing drag.

Rudy Project also works hard to ensure comfort, cooling and easy fit adjustment. The Flow Through ventilation system allows air into the structure, circulate, and exhaust, all without whistling. The Spectrum Helmet features 15 vents, all which serve to keep you cool and as dry as possible, even during max effort rides in the middle of summer. The renowned Rudy fit is achieved via a true system of components. The lightweight Adaptive Airframe Band augments the ventilation while providing comfort up front. Rudy's Adjustable RSR10 Retention System dial is minimal, easy to use and allows for secure fit with a very personal feel. We have always liked the soft flexible straps with the sure-handed Fastex Buckle Closure System because it simply works, even with fatigued hands at the end of a long ride. The Divider Pro Side Buckles, which control the Y-shape and location of the straps are minimal, lightweight and a breeze to adjust.

The antimicrobial pad system is removable, can be swapped out, and are handwashable. Rudy provides this standard set, as well as the Bug-Stop net and integrated padding, We have sold Rudy Project helmets for years and the Bug-Stop has been a key buying point for many cyclists. Feedback from riders indicates that for many headshapes, the Spectrum runs a little large, so if you on the cusp, we recommend you size down.
