If you're running Eclat's AK or Elevate Guard Sprockets and your guard has seen better days then this is the replacement you need. Built from a high-impact, low-friction nylon and fibreglass blend that's super durable for friction-free grinding. The Eclat Viper Nylon Sprocket Guard is unique in its construction as it doesn't sit on the surface of the sprocket but is sunken into the sprocket itself to take the stress of impacts off the guard bolts. ###section### Product Specs TYPE: MATERIAL: WEIGHT: 99.8g (3.52oz) Colour: Black; Size: 25T, 28T
