When time is of the essence no other helmet will get you from start to finish faster than the S-Works TT. In order to create the fastest TT helmet out there we turned to the design of the S-Works McLaren TT to make a helmet that truly differentiates itself from the competition. The biggest innovation found on the S-Works TT are the patented Gill Vents that pull air into the helmet & allow it to freely flow out of the rear exhaust port. This makes for a time trial helmet thats not only fast (62 seconds over 40 kilometers compared to a standard road helmet to be exact) but will also keep you cool on the course. A fast helmet is useless if it doesn’t fit well after all so that’s why we specd the S-Works TT with our height-adjustable Mindset micro-dial fit system that makes for a tremendous fit & fast transitions. This along with our lightweight 4X Dry Lite webbing that won’t stretch out with sweat or water & Instrap webbing system for ultra-light construction & security make for a TT helmet that provides comfort over the long haul. Each S-Works TT helmet has been designed around a removable shield which means that you get a TT helmet thats just as fast with a shield as it is with sunglasses—the first of its kind. Each helmet comes with two removable shields (Smoke & Clear) that allow for the ultimate in visibility when cranking out power while in the aerobars. With our most advanced Win-Tunnel-developed aerodynamics & ventilation the S-Works TT helmet is your best option for pure speed. Advanced wind-tunnel-developed aerodynamics & ventilation save 62 seconds over 40km compared to a standard road helmet.
