The Muc-Off Stealth Tubeless Puncture Plug is built for riders who want their puncture backup stored on the bike, not rattling around in a pocket or saddle bag. It tucks into compatible bar ends, giving you a 2-in-1 reamer and plug tool on one side and a trimming knife on the other. For mountain bike, gravel and drop-bar riders who already run tubeless, that means a cleaner setup and one less thing to forget before a ride.
In use, this kit is all about convenience and coverage. You get thin, medium and thick tyre worms, so you can match the plug to the size of the hole rather than forcing one size into everything. The included 17 mm, 19 mm and 21 mm expanding silica plugs broaden bar fit, and real-world testing points to a secure, quiet fit once installed. The trade-off is that removal is not the fastest because you need a 4 mm Allen key to get the tools out, so it makes the most sense if you already carry a multitool or run an on-bike tool setup.
Where this Muc-Off kit stands out is its stealth storage, tidy finish and practical all-in-one format. It can repair holes up to 6 mm, and the knife makes it easy to trim excess worm neatly after the plug is seated. If you mostly ride MTB or aggressive gravel, or you simply like a bike with essential tools hidden in plain sight, it’s a smart upgrade over a loose plug kit.
Ideal for tubeless MTB, gravel and drop-bar riders who want a clean cockpit and a puncture repair tool that stays on the bike full-time.
Bar-end storage
The repair tool and trimming knife store inside your handlebars, so your backup puncture kit is always on the bike and ready to go.
Three worm sizes included
Thin, medium and thick tyre worms let you match the repair to smaller road punctures or bigger gravel and MTB damage.
2-in-1 reamer and plug tool
The stainless steel tool lets you prep the hole and install a plug with one compact setup, which keeps trailside repairs simple.
Fits a wide range of bars
Supplied with 17 mm, 19 mm and 21 mm expanding silica plugs to suit different internal handlebar diameters.
Secure, tidy installation
The expanding plug system and threaded 4 mm Allen-key fitting give a snug hold once installed, with no bag or strap needed.
Trimming knife included
You can cut excess worm neatly after the repair, helping leave a cleaner finish and reducing the chance of the plug catching.
Stealth looks with colour choice
The CNC-machined 6061 aluminium bar ends give you a durable finish and a colour-matched look if you care about a tidy build.
Every detail as listed by the manufacturer.
