When time is of the essence, no other helmet will get you from start to finish faster than the Specialized S-Works TT helmet. To create the fastest TT helmet available, Specialized turned to the design of the S-Works McLaren TT helmet for inspiration. The standout feature of the S-Works TT is the patented Gill Vents, which allow air to flow into the helmet and out of the rear exhaust port. This design not only makes the helmet faster (62 seconds faster over 40 kilometers compared to a standard road helmet), but also keeps the rider cool.Specialized has partnered with MIPS researchers to introduce MIPS SL, an ultra-light and supremely comfortable version of MIPS technology available exclusively on Specialized helmets. With MIPS SL, the technology is integrated into the helmet padding itself. The minimalist "watchband" attachment system of MIPS SL provides rotational movement in every direction, offering brain protection while improving comfort and reducing weight.A fast helmet is only effective if it fits well, which is why the S-Works TT is equipped with the height-adjustable Mindset micro-dial fit system. This ensures a precise and comfortable fit, allowing for fast transitions. Specialized has also incorporated lightweight 4X DryLite webbing that doesn't stretch with sweat or water, as well as an Instrap webbing system for secure and lightweight construction.The S-Works TT helmet features a removable shield, allowing for the use of a shield or sunglasses depending on preference. Each helmet comes with two removable shields (Smoke and Clear) for optimal visibility while riding in the aerobars.With advanced aerodynamics and ventilation developed in the Win-Tunnel, the S-Works TT helmet is the best choice for pure speed.
