The kit is easily accessible for quick tire repairs and comes with five high-quality tubeless plugs that can also be stored inside its body. The tool insert kit is made of lightweight, durable machined aluminum and features hardened steel tips. The kit is easily accessible for quick repairs and comes with five (small), eight (medium) or 11 (large) different tools ideal for today's modern bikes (see specifications below). Each tool also serves as a handlebar end cap and comes with three different sized O-ring fasteners to ensure a secure fit inside most handlebar openings.
