GUB Angle-Adjustable Bike Computer Mount — Stem Top Cap for 1 1/8" Steerer, CNC Aluminium, 4 Adapters

GUB's angle-adjustable stem top cap mount lets you attach most cycling computers on top of your steerer tube for an easy, aerodynamic, and highly visible ride display.

This compact mount replaces your bicycle's stem top cap and holds popular head units from Garmin, Wahoo, Bryton, and Cateye. Machined from high-strength aluminum with precision CNC finishing and integrated plastic components, the holder is engineered to be lightweight yet sturdy. It includes four interchangeable adapters so you can mix and match devices across ride types, and the pivoting interface gives you micro-adjustments for the best line of sight while riding.

How does the angle adjustment improve my ride visibility?

The adjustable tilt lets you dial the screen angle to minimize glare and keep data readable whether you’re tucked low or sitting upright. Small angle changes make a significant difference in reflection and sightline, so you stay informed without shifting posture mid-ride.

• Pivoting head for micro-angle changes to reduce glare
• Top-of-stem position places the computer directly in your forward view
• Stable clamp design prevents wobble at varied angles

Which bike computers and adapters are supported?

The mount ships with four adapters that cover a wide range of popular computers, letting one mount work across different brands and models. It’s compatible with many Garmin Edge models, Wahoo Elemnt series, Bryton units, and Cateye computers for flexible device pairing.

• Works with Garmin Edge 20 / 25 / 130 / 500 / 510 / 520 / 520Plus / 800 / 810 / 820 / 1000 / 1030
• Compatible with Bryton models like 100, 300, 310, 330, 530, 10, and One
• Supports Wahoo Elemnt, Elemnt Bolt, and Elemnt Mini plus many Cateye units

Is installation difficult and what bike stems fit?

Installation is straightforward: remove your existing top cap, fit this mount, and secure it to the steerer using the included fastener. The mount is made to fit standard 1 1/8" (28.6 mm) steerer tube stems and keeps the computer centered and secure without complex adjustments.

• Designed for 28.6 mm (1 1/8") steerer tube stems
• Top-cap replacement installation — no special tools beyond a common Allen key
• Compact footprint preserves handlebar reach and cockpit clearance

What materials and durability features should I expect?

GUB blends CNC-machined aluminum with reinforced plastic components to balance weight and strength. The aluminum body resists fatigue while plastic interfaces protect device mounts and adapters; together they deliver long-term reliability under regular road or gravel use.

• High-strength aluminum alloy main body for structural rigidity
• Precision CNC machining for consistent fit and finish
• Plastic adapter components reduce wear on your computer's mounting lugs

Who is this for: Riders who want a low-profile, secure, and adjustable way to position a GPS or bike computer directly in their line of sight. It’s well suited for road cyclists, gravel riders, commuters, and anyone who swaps head units between bikes and needs a reliable, lightweight stem-mount solution that supports multiple brands.
