Stem Cap Mount Adjustable

Quad Lock Adjustable Stem Cap Mount

The Quad Lock Adjustable Stem Cap Mount provides a clean, centred and highly adjustable way to securely mount your smartphone to your bike.

Designed to mount directly above the stem, it keeps your phone positioned neatly in the centre of the cockpit without taking up valuable handlebar space. It's an excellent solution for mountain bikes and e-MTBs where brake levers, shifters, dropper remotes and e-bike controls can leave limited room on the bars.

The hinged design allows the phone angle to be adjusted for a clear viewing position, while Quad Lock's proven dual-stage locking system keeps your device securely attached over rough terrain.

Clean Stem-Mounted Position

Rather than clamping around the handlebar, the Adjustable Stem Cap Mount positions your phone centrally above the stem.

This creates a clean cockpit while leaving more handlebar space available for lights, controls and other accessories.

Adjustable Viewing Angle

A hinged arm allows the phone position to be adjusted and then securely tightened using the supplied hex key.

The mount can also be reversed to provide additional clearance and accommodate a wider range of stem angles, making it particularly useful on modern mountain bikes with short stems and varied cockpit setups.

Built for Riding

The mount is manufactured from CNC-machined aircraft-grade aluminium with a black anodised finish for a strong, lightweight and premium construction.

Combined with Quad Lock's secure dual-stage locking mechanism, it's designed to keep your phone firmly attached while riding over rough roads and trails.
