Ahead of the stem rather than on top of it, the Out Front Mount keeps the screen in your line of sight and leaves the bar clean. It weighs 3.04 ounces, fits 22, 25.4, 31.8, and 35 mm bars, and rotates for over-stem mounting. That range covers more bar sizes than most mounts here, and the slim arm looks less like a phone holder and more like part of the cockpit.
We think the dual-stage lock is the reason to pay for the system. The case twists on, clicks once, then clicks again; the second stage is the check that stops a half-turn from becoming a dropped phone. It takes a little practice to learn the motion, but the payoff is a connection that feels planted on rough pavement. The mount is light enough that we forget it is there until we need the screen.
The mount is light because much of it is thermoplastic, and the arm is the part we inspect after a hard knock; a crash that twists the bars can put a lot of load through that joint. The screws and the plastic collar are worth a look before the next ride. That is the price of the slim profile.
Bottom line: Riders already using a Quad Lock case get what we think is the cleanest out-front mount here; the dual-stage lock and wide bar fit justify the premium.
