The most mutual causes of a tubeless puncture and how to fix them
A puncture in tire tread or sidewall
Fixable on the trail? Aye
Fourth dimension needed for repair: i-5 minutes
This kind of puncture is acquired by modest thorns, sharp rocks or nails etc on the trail. It is probably the most common tubeless puncture, and luckily also one of the easiest to gear up. In fact, you might have already punctured on the trail without realising, as the tubeless sealant in your tires often seals these small punctures immediately. If, however, the hole is as well big for the sealant to fix on its own – often acquired by a pinch flat – you lot will need a tubeless plug kit. The first step is to find the hole (or holes) and wipe abroad any surrounding clay. If you are riding in a group, ask a buddy to keep their finger over it to minimise air-loss. So, rapidly thread the tire plug through the plug installer.
Depending on the size of the pigsty and the plugs, there are 2 techniques to plug the tire. For smaller punctures, push the plug into the hole until it fully disappears inside the tire. Then carefully pull the installer out, until five-ten mm of the plug is visible. Use your fingers to hold the plug in place and remove the installer. If you are sealing bigger punctures with larger plugs, push button the plug into the tire just over halfway, then that a "V" shape is left, and remove the installer.
Once the plug is installed, spin the wheel to let the sealant coat the tire and re-inflate if needed. In our experience, if installed correctly, tubeless plugs can concluding the lifetime of the tire and do not need to exist removed. Withal, information technology is worth trimming the exposed plug to prevent it from ripping out nether heavy braking.

In short, you have burped a tire. At that place are ii possible causes: either yous were running very low tire pressure, compromising your tire's stability or you just hit the plow really actually hard. Either way, the set is simple. All you take to exercise is re-inflate the tire and keep riding. Nosotros recommend checking out our Tire Pressure level Guide to find your perfect pressure and prevent burping in the future. You should also summit upwardly your sealant before your next ride, every bit you most likely lost some during the burp. If yous burp on a regular basis, fifty-fifty with high tire pressures, you are very likely running a tire that is also wide for your rim width.
A cutting in the sidewall

Your only option is to install a tube and ride home. If the cut is really big, effort protecting the tube by sticking some tape or plastic etc in between the tire and the tube. Depending on the severity of the damage, yous can try fixing the tire at home by thoroughly cleaning the tire within and out, roughening up the inside of the tire with sandpaper and applying a tire patch with vulcanising glue.

If spoked snapped, replace information technology… Make sure you know why the spoke punched through the tape: check for even spoke tension and make certain your rim is an intact running truthful. Re-tape the rim (with new record) and set tubeless. Cheque out our Ultimate Guide to Tubeless for everything yous need to know!
