I'm relatively new to tubeless. I have a 3-4mm hole in my Gravel King that refuses to seal. I repaired it a while ago with gaffer tape inside and it lasted 6 moths or so but has now burst again. Bacon strips and my clumsy tooling isn't fixing it, I think I need to apply a patch from the inside. Do I need a special patch for this or can I use any old school puncture patch? Any brand recommendations?
I've had good success with Rema Tip Top puncture repair patches. Preparation is key - make sure the area is clean, roughed up, and the rubber cement has gone tacky before applying.
tyre repair plugs off ebay (sometimes known as mushroom plugs). Have a look for the smallest ones you can find as most are for cars and too big. Preparation is barely an issue in my experience of using them
Rema Tip-Top or the Weldtite ones are as good as each other.
On the rare occasions that I have to I always use mushroom plugs from eBay. Never had one fail
Mushroom plugs do the job. I got a selection of sizes from Vittoria.
I highly rate the Rema Tip Top kit - https://www.rosebikes.com/rema-tip-top-tt13-tubeless-repair-kit-2674083 - not that easy to find in the UK though.
+1 for mushroom plugs.
Generic mushroom plugs, these have been good for me https://www.ebay.co.uk/itm/131208504777
Bonded with Rema SC-BL, some useful advice in these threads: https://singletrackworld.com/forum/topic/puncture-repair-vulcanising-solution-vs-rubber-cement/ https://singletrackworld.com/forum/topic/mushroom-plugs-do-you-need-glue-as-well
Mushroom plugs. The blue edged patches are also designed for tyres and sometimes you find them with specific glue for tyres. I've failed to buy a pack in the past but sometimes you get one blue patch in a standard puncture repair kit.
Try Rema Tip Top patches or small mushroom plugs from eBay.
Top tip, if the hole is too big to plug i will sew it up with dental floss and stick a standard inner tube patch on inside of tyre, works well
Also used a mushroom plug on a hole that wouldn't seal properly. Has been perfect since
Helpful tips here. My gravel king sk's have a couple of tiny 1-2mm holes that aren't sealing. Some were OK with an inner tube patch but looks like the mushroom plugs will be good for the job.
