Quad Lock Cycling Stem Cap Mount

Save space and enhance your bike cockpit with the Quad Lock® Stem Cap Mount. Designed to fit seamlessly between your bike's stem and top cap, these mounts are compatible with a wide range of stem angles—ideal for road, gravel, and mountain bikes.

Secure & Lightweight Performance

Engineered from ultra-light, CNC-machined aircraft-grade aluminum, these are the strongest and lightest Quad Lock® bike mounts yet. Built to endure the toughest rides, they’re rigorously tested for strength and durability. With the patented dual-stage locking mechanism, your smartphone stays locked in—even over rough terrain or aggressive descents.

Minimalist Design for a Clean Look

With sleek black hardware and a compact, low-profile lever, the Stem Cap Mount offers a clean, minimal look without compromising function. It mounts directly to your bike’s stem cap, eliminating handlebar clutter and keeping your setup tidy.
