Aluminum Alloy Top Cap GPS Mount Bracket for Garmin Edge

Aluminum Alloy Top Cap GPS Mount Bracket - Stem Computer Holder for Garmin Edge, Bryton Rider, Cat Eye

Move your bike computer from crowded handlebars to the center of the stem for cleaner lines and safer sight lines. This top-cap mount replaces the standard stem cap, locking your Garmin Edge, Bryton Rider, or Cat Eye head unit in a rock-solid position that survives enduro roots and downhill drops. CNC machined aluminum keeps weight low and strength high, while the supplied bolts let you swap caps in under five minutes.

Ideal Examples of Usage
- Enduro racing – keeps the computer protected behind the stem instead of exposed on the bars.
- Downhill shuttle days – lowers the unit out of crash range yet stays easy to read on lift rides.
- Gravel or bikepacking – frees bar space for aerobars, lights or a handlebar bag.
- Commuting – centers navigation cues so you glance down without taking eyes off the road.

Why This Mount Is the Perfect Buy
Handlebar out-front mounts can twist in crashes and clutter brake and shifter cables. A stem cap mount is minimalist, secure, and uses hardware you already have. One small upgrade declutters the cockpit, protects your investment, and works with three major computer ecosystems.

Interesting Facts About Stem Cap Mounts
- Replacing the stem top cap does not affect headset preload as long as the original bolt torque is restored.
- Aluminum alloy offers almost three times the tensile strength of most plastics at the same thickness.
- Positioning the GPS over the steerer keeps it in the bike’s center of gravity, reducing vibration readings.
- Switching to a top cap mount can free up 40 to 50 mm of bar space for lights or aero extensions.
- Keyed plastic inserts allow one mount to serve Garmin quarter-turn, Bryton, and Cat Eye tabs with a quick swap.
