Bontrager Ballista MIPS Road Bike Helmet

The Bontrager Ballista MIPS with the renewed BOA retention system can be made to fit even more comfortably, more accurately accommodating any head size. The Ballista MIPS is safer than the regular version because of the integrated MIPS system, which dissipates part of the energy released in a crash by letting the inner shell move with your head. The Bontrager Ballista also excels when it comes to aerodynamics, ventilation, and comfort. According to wind tunnel testing, the Ballista is the fastest bicycle helmet on the market.
