Crankbrothers Plug Mate Tire Anchor Kit Tubeless plugs that actually stay put. Standard tubeless plugs work - until a hard landing or aggressive brake sends them right back out. The Crankbrothers Plug Mate is a smarter solution. A unique bullet-shaped anchor rotates sideways inside the tire casing to lock the plug firmly in place, even under the kind of impacts that send ordinary plugs packing. It installs with any common tire plug fork, including Crankbrothers F-series, M-series, SOS, and Cigar tools, so no special equipment required. Each kit includes anchors in two sizes and a mix of thin and thick plugs to cover whatever the trail throws at you. Features Unique rotating anchor design locks sideways inside the tire casing for a semi-permanent, blowout-resistant repair that holds through impacts, landings, and hard braking Two anchor sizes included - 3 small (yellow) and 3 large (orange) reusable anchors - to accommodate various plug dimensions and puncture sizes Tire plugs included - 10 thin (brown) and 5 thick (black) plugs for a wide range of puncture types Compatible with most common plug tool forks including Crankbrothers F-series (F11/F16), M-series (M13/M20), SOS, and Cigar tools Reusable anchors made from durable plastic that won't damage rims or tire casings Requires less effort to install than competing designs, with no special tools needed | Crankbrothers | Plug Mate Plug
