A fast descent with a friend leading the line is worth filming from the helmet, and the KOM Cycling Helmet Mount holds a bike light, an action camera, or another compatible cycling accessory up there. The included adjustable strap secures the black mount to the helmet. What Our Gearhead(R) Experts Are Saying:"GoPro-style connections and Garmin and Wahoo quarter-turn fittings both work on this mount, so my camera and my light share one helmet setup. The integrated tightening handle snugs the strap down by hand, which keeps adjustments quick without a tool in my pocket."
