Product details

Quad Lock Stem Cap Mount Pro Adjustable — Bike Phone Mount │ Fresh Air Kelowna

The Quad Lock Stem Cap Mount Pro Adjustable is a precision-engineered phone mount for cyclists who want a clean cockpit and rock-solid phone security — without strapping anything to their handlebars. Its screw-tightened adjustable hinge accommodates upright stems from +15° all the way to +55°, making it an ideal match for e-bikes, commuter rigs, mountain bikes, and gravel setups.

Forged from aircraft-grade aluminium and secured by Quad Lock's patented dual-stage twist-and-lock, your phone stays put whether you're grinding up Knox Mountain or spinning the KVR Trail between Kelowna and Myra Canyon. At just 42g, you won't feel it — but you'll always see your navigation. Available now at both Fresh Air Kelowna locations.

   
KEY FEATURES

Aircraft-grade CNC aluminium construction — black anodized, forged, and precision-machined; built to handle rough terrain without adding meaningful weight to your build

Adjustable hinged design — screw-tightened hinge accommodates stem angles from +15° to +35° in standard orientation, and up to +55° when reversed; covers road, gravel, MTB, commuter, and e-bike stems

Patented dual-stage twist-and-lock — quick one-handed phone attach and detach in seconds; stays securely locked even on rocky, rooted, or rough-paved surfaces

Dual-sided reversible head — attach the locking head on either side of the mount body for your preferred screen position and optimal viewing angle

Standard stem compatibility — fits 28.6mm (1⅛") steerer tubes found on most modern road, gravel, commuter, and mountain bikes; not compatible with quill stems or some proprietary aero top caps

Included fit hardware — comes with a 5mm headset spacer (28.6mm) and a 3mm Quad Lock 360™ Index Mount Spacer so you can fine-tune cockpit clearance right out of the box; hex key included

Integrated cockpit profile — installs between the stem and stem cap rather than on the bars, eliminating clamp bulk for a sleek, minimal look

App-ready navigation — keeps Ride with GPS®, Strava®, Google Maps, or any navigation app in your sightline; detach instantly for photos or calls without unlocking anything

WHO IS THIS FOR?

Best for cyclists who want the cleanest possible cockpit and a phone mount that disappears into the bike — road riders, gravel adventurers, e-bike commuters, and mountain bikers running upright or moderate-angle stems. The adjustable hinge makes it especially well-suited to e-bike riders who rely on navigation for longer Okanagan routes. Compatible with standard 28.6mm (1⅛") steerer tubes.

FAQ

Q: Will the Quad Lock Stem Cap Mount Pro Adjustable fit my bike? A: It fits standard 28.6mm (1⅛") steerer tubes, which covers the vast majority of modern road, gravel, commuter, e-bike, and mountain bikes. It won't work with older quill stems or certain proprietary aero road bike top cap systems. Not sure about your setup? Bring the bike into either Fresh Air Kelowna location and our staff will check compatibility on the spot.

Q: How much does the angle actually adjust — and is it easy to set? A: In standard orientation the hinge covers stems from +15° to +35°; flip the mount to its reversible position and you get up to +55° of clearance — which handles most upright commuter, e-bike, and MTB bars. Once you've dialled in the angle, the included hex key locks the hinge firmly in place. No tools needed after that for daily phone attachment and removal.
