Cyclists, these colorful valve caps are such an easy way to add some personality to your ride! You get 20 pieces total with 10 different colors - green, blue, gray, red, orange, silver, purple, sky blue, gold, and pink. Two of each color means you can mix and match or keep your wheels coordinated. Made from lightweight aluminum alloy, these caps are corrosion-resistant and built to last through all kinds of weather. The 1.8cm height and 0.5cm inner diameter fit standard Presta valves perfectly, keeping out dirt, mud, and moisture that can mess with your valve stems. The knurled threads make them easy to screw on and off with your fingers - no tools needed. They work great on mountain bikes, road bikes, fixies, hybrids, pretty much any bike with Presta valves. Just a heads up - these won't fit Schrader valves (the kind cars use). For such a small upgrade, these caps make a big visual difference and actually protect your valves. Whether you're building up a new bike or just want to refresh your current ride, these colorful valve caps are an affordable way to add some flair!
