When a hole is too large and too severe to seal, the Muc-Off Stealth Tubeless Puncture Plug is the ultimate replacement tool, cleverly stored in your handlebar ends. The included expanding silica plugs cover most handlebar sizes for MTB, road, and gravel bikes. The high-quality handlebar ends are made from CNC-machined aluminum and are available in 12 anodized colors to match your ride. Each lightweight and durable set contains everything you need to keep going when you're dealing with a hole that just won't seal: a 2-in-1 stainless steel reaming tool for puncture plugs, a selection of tire worms in various sizes, and a trimming knife.
