Spanish excellence.

The Chrono Aero WT Helmet design was developed through extensive wind tunnel testing by Catlike's engineers. While we're starting to see more manufacturers building their time-trial lids with shorter tails and stubbier backsides, Catlike continues to design its TT helmet in accordance with the hard data stemming from its tests. Because of this, the Spaniards at Catlike have tweaked the vetted Chrono Aero WT by adding several updates, but they keep the helmet's overall efficient makeup relatively unchanged. After all, when the testing can't be improved upon, there's no reason to change.

Catlike's hours in the design lab ensure that at your head will remain comfortable through the duration of your time-trial event. The singular, in-molded shell features Catlike's CES (Crash Energy Splitter) technology that disperses impact energy along the internal skeletal structure of the helmet. Catlike uses an open-cell foam to pad the flexible ear flaps, making the helmet much easier to pull on and eliminating any painful pinching along the side of your head. Dialing in your fit is also a painless affair, as Catlike has equipped the Chrono Aero with a cradle for the back of your neck. This cradle is fully adjustable, and independent of the helmet straps. Its tension can be tightened or loosened with the simple turning of the ratchet dial — like Giro's RocLoc or Garneau's Spiderlock systems.

The helmet has only a single ventilation port at the front of the helmet -- a single, massive air intake shaped like the Catlike logo. It's a refreshing design choice that is as bold as it is functional, and one that further serves to illustrate Catlike's predilection for unorthodox design in differentiating itself from the masses. The helmet also features two streamlined exhaust ports on the back and tail of the helmet that leave airflow largely uninterrupted as you slice through the wind. The Chrono Aero also comes equipped with a clear, interchangeable windscreen.

The Catlike Chrono Aero WT is the same helmet issued to the Spanish team MoviStar for time-trial stages. It is available in either Small (54 - 56cm) or Medium/Large (57 - 60cm) sizes, and comes in Matte Black, Matte Red, and Matte White.
