What Our Gearhead(R) Experts Are Saying: "I love this mount for its clean, low-profile setup-no bulky brackets or cluttered cockpit. The phone locks into place instantly with magnetic alignment and vacuum suction, and even on rocky descents, it stays rock solid. When I'm done riding, I just twist it off, and the bike still looks super sleek." The Fidlock VACUUM Head Cap Base is the definition of elegant engineering for your cockpit. Designed for riders who want a secure, streamlined mount for navigation or ride data, it uses Fidlock's unique combination of magnetic alignment and vacuum suction to hold your phone perfectly in place-stable on rough terrain yet effortlessly detachable with one hand. This two-part system installs neatly into any 1 1/8" threadless headset, replacing your stem cap for a clean, centered look. Once the magnetic force guides your phone into place, the vacuum system locks it down with unwavering strength. A simple lever release frees your device instantly, while the 360deg rotatable mount allows flexible screen positioning without unwanted spin. Compatible with all Fidlock VACUUM phone cases and universal patches, the Head Cap Base brings together form, function, and Fidlock's precision technology-creating the ultimate minimalist mount for riders who want performance without distraction.
