What Our Gearhead(R) Experts Are Saying:"The Class 1 optics shield gives a completely undistorted view down the road, with none of the fish-eye effect you get with a standard drape-formed lens. The hydrophobic coating clears moisture fast enough that I'm not reaching up to wipe the shield on a wet day."Why We Like ItSpecialized used CFD modeling to reposition the rear of the TT 5 closer to the rider's shoulders, which cuts the eddy of air behind the helmet that generates drag. The shell shape came out of extended Win Tunnel sessions with World Tour TT specialists, making it the fastest TT helmet Specialized has produced.
