Ideal for tough rides and daring stunts - the Axle from Smith! The BMX and trial helmet is made using a proprietary Bombshell PLUS construction that provides protection against sharp rocks, stones or roots. Under the hard shell a multi-impact EPP inner shell makes sure that shocks and impacts are absorbed. The Lifestyle Fit System guarantees a comfortable fit. It provides a dynamic and flexible fit around your head, so that the helmet covers a large range of head circumferences without problem. 13 ventilation openings provide a cool breeze, as does the AirEvac ventilation system which channels airflow through the helmet. The Smith Axle is not only made for the bike park, it is suitable for everyday use thanks to its clever design!
