Save Mammut's Bionic Express Quickdraw for clipping the bolt before the crux move on the hardest climbs. Its Bionic carabiners boast resounding breaking strengths to keep you confident whether you send or flail. The wire gate reduces weight and flutter while clipping, and the straight gate styles a keylock nose for snag-free convenience. The super-skinny and super-strong Dyneema sling features a rubber retainer that stabilizes the wire carabiner when you're clipping.
