Stem Cap Mount

Description |

Clean up your cockpit while keeping your phone at the perfect angle with the Quad Lock Stem Cap Mount. This ultra-light, precision CNC-machined aluminum mount installs directly between your bike’s stem and stem cap, lifting no more than a standard spacer.

Built for strength, it features Quad Lock’s dual-stage twist-lock system to keep your phone secure, even across rough terrain. The dual-sided, reversible head lets you fine-tune your viewing setup, while included spacers (5 mm headset and 3 mm Quad Lock 360 index spacer) ensure fit on most 1 1/8″ stems. The result: a minimalist, reliable mount that blends into your ride—only found at Dismount, shipping across Canada.
