With the Muc-Off Stealth Tubeless tire plugs we can utilize unused storage in our bar ends to hold much-needed emergency trail supplies. We've been there, ripping down our favorite trail when all of a sudden, 'hssssss' hits and we know our sealant won't finish the job. These nifty little bar end plus only weigh 33g, so we won't be noticing them while ripping down the trail. The kit comes with a serrated knife as well, so we can cut loose ends once we jam a plug into our tire.
