The WASP is all about Watt Saving PerformanceWith extensive wind tunnel testing and athlete feedback Lazer are proud to present the fastest commercially available TT helmetIntegrated adjustable visor can be moved up and down to increase ventilation or improve aerodynamicsTripwire technology reduces the laminar effect of air moving past the plastic of the helmet and so creates a narrower, low pressure, wake and hence less pressure drag. The reduction in pressure drag causes the helmet to travel at the same speed for less energy inputThe tail on the WASP helmet can also be removed and with the short tail conversion kit, the helmet can then be converted into a WASP Air for longer races or days with hard cross windsThe Lazer Advanced Turnfit® Retention System makes sure the helmet is snug and comfortable on the headIncludes both mirror and clear lens visorsIn-mould construction4 cooling ventsWeight: 500 g for a size mediumSize: Small 52-56cm, Medium - Large 55-61 cm
