Hey cyclists! If you're looking to dial in your perfect handlebar height, this 7-piece aluminum spacer kit has got you covered. These spacers are specifically designed for 1-1/8 inch steerer tubes and come in a super handy variety of sizes - you get one 15mm, three 10mm, one 5mm, one 3mm, and one 2mm spacer. That means you can fine-tune your handlebar position with millimeter precision! Made from lightweight aluminum alloy, these spacers are seriously durable but won't add unnecessary weight to your bike. The anodized surface not only looks slick but also provides excellent corrosion resistance, so they'll stay looking good through all kinds of weather. Installation is a breeze - just slide them onto your steerer tube above or below your stem. I love having multiple size options because it lets me experiment with different handlebar heights until I find that sweet spot for comfort and control. Whether you're riding mountain bikes, road bikes, or BMX, these spacers provide the flexibility you need to get your bike setup just right. The quality is impressive - the machining is precise, the edges are smooth, and they fit perfectly without any play. At just 48.6 grams for the whole set, you're getting professional-grade adjustment capability without the weight penalty. Seriously, if you're tired of being limited by whatever spacers came with your bike, this kit gives you all the options you need to optimize your riding position.
