ALUMINUM STUD BODY: Using aluminum saves weight and reduces rotating mass, making the steering of your bike feel faster and giving you better acceleration. Cheaper studs use a heavier steel body and add weight. CONCAVE CARBIDE TIP: The shape of the carbide tip helps the stud bite into the ice better than standard studs and improves traction. The carbide material adds durability to create a long lasting stud. ANODIZED IN FUN COLORS: Add some fat bike flair and some fun to your studded tires. Our bike studs are anodized in four colors for the ultimate studded tire bling. DESIGNED IN ANCHORAGE, ALASKA: We have a lot of experience riding fat bikes and with studded tires. These bike studs are designed for cold weather riding in the iciest conditions. LIFETIME WARRANTY: If you ever lose or damage a stud, please reach out to us. We'll send you a replacement.
