A lot of people think that if you have a hole too big to be repair by the sealant, your expensive tubeless tire is dead or has to be run with a tube in it.
Even if doing a huge puncture like that is rare, it can happens especially if you ride on rocky terrain like we do in the south east of France at Provence Enduro. Luckily there is a solution now using the same principle that mechanics are doing to fix your car tire: it’s the Weldtite Tubeless repair kit. And bonus, you can even fix your puncture on the sid of the trail without removing your wheel from your bike.
The kit provides a set of string, some special glue, a needle to insert the string and a rasp tool.
Once the hole is located and the foreign object remove, use the rasp tool to smoother the hole and makes it better and apply some glue solution in it.
Insert half of the string into the eye of the needle tool and coat everything with the glue. Insert the tool/string the hole until about 1/2 of the string left on the outside. Slowly pull the needle out the hole.
Cut the string about 3 mm from thread and now you can inflate the tire and you’re ready to go.
I tested on a big hole cause by a rock in La Moulière and it works first try.
Tips: The string are very long, cut them in half, it’s enough and it double the number of string you have.
The repair kit cost about 10€ and when you’re gonna run out of string, they are sold separately. It’s easier to find on the internet spare strings than the initial kit needed to install them I found mine on http://www.cycletyres.fr/.
I strongly recommend this product, it’s cheap, it works, it’s easy and fast to do and even can be done on the side of the trail.
