Cyclists, this VGEBY stem mount is a game-changer for positioning your bike computer right where you need it! Made from lightweight aluminum alloy, this sturdy mount attaches to your bike's stem top cap, keeping your computer centered and easily visible while riding. It's compatible with 28.6mm diameter steerer tubes, which fits most modern road and mountain bikes. The installation is straightforward - just replace your existing top cap with this mount, and you're ready to go. Weighing only 21g, it adds virtually nothing to your bike's weight while providing a secure platform for your cycling computer. Available in two options: one compatible with Cat Eye computers, and another that works with various GPS units like models 1000, 820, 810, 800, 520, 510, 500, and 200. The black finish looks sleek and professional on any bike. Having your computer positioned right in front of you makes checking your stats much safer than looking down at your handlebars, especially on steep terrain or during intense rides. When you're not using it, the mount is easy to disassemble. Plus, with a 180-day satisfaction guarantee, you can buy with confidence knowing the company stands behind their product!
