Quad Lock QLM-SCM Bike Handlebar Mount

The Quad Lock® Stem Cap Mount is designed to secure your smartphone to the top of your bicycle's stem, offering a compact, space-saving solution for navigation and data monitoring while riding. Crafted from forged and CNC-machined aircraft-grade aluminum with a black anodized finish, it combines lightweight design with mechanical strength. The patented Quad Lock® Twist, Lock system with two-stage locking keeps your smartphone securely attached even on rough terrain, while the reversible head allows for optimized positioning based on the angle of your stem.
