Muc-Off Ultimate Tubeless Setup Kit, DH/Trail/Enduro - Tubeless Conversion Kit for Bikes - Includes Tubeless Tire Sealant and Tubeless Valve Stems

Went tubeless on my trek marlin 5 and it’s super easy to do! This kit is a must, after a bunch of rides it works great. My bike wheels weren’t tubeless ready but after this kit they were

Easy to use and seals every time. I'm actually using this in a road bike (oops), but it has worked better than any other sealant I've tried. Really easy to install / top up with the sachets and I ride in an area with a lot of goat heads--I find this seals quickly. When I was riding this area on tubes, I was on the side of the road changing out tubes nearly every other ride!

Good item!

Worked on my Attoz 2 MTB, just a reminder to stretch and pull down hard on the tape. My son did not he taped it trying to have tape fill every curve and it ended up leaking. As long as it’s on the edges it will work great and keeps it from wrinkling which can cause it to leak. Took our bikes on a 12 mile rocky trail and felt amazing. Did not have to worry about tubes popping.

I used this on my tubeless kit on my 2023 Trek Domane, which is a road/gravel bike with 21mm rims. I ordered the road/gravel bike kit designed for 19mm-21mm rims which comes with 21mm rim tape and it did not work. It was leaking through some of the spokes which tells me the rim tape wasn't working properly. After a lot of research, I found that the rim tape should have been slightly wider. I ordered a 2nd kit, but this time I ordered the X-Country kit designed for 23mm-25mm rims and comes with 25mm rim tape. I installed this kit about an hour ago and so far it's MUCH better. No leaking, no hissing, no air pressure loss. Other than this, make sure your rims are nice and clean (use isopropyl alcohol) and take your time. Pull the tape nice and tight (I did two full wraps on each rim) and take the time to use a cloth and press the tape down making sure it is completely adhered to the rim. Do not over-tighten the valve stem or use tools on them when installing them. Finger tight is all you need!

I'm new to tubeless. I was a long time hold out. Now a long aside about what else I tried first. I decided that I was going to give it a try with my Trek bike, and figured that I'd give their TLR rim strips a shot. First off, rim strips are roughly $20. And there is nothing whatsoever on Trek's site or anywhere else that suggested that the price was for a single rim strip. So I bought it and had it shipped to my LBS and took it home. I was unpleasantly surprised to find out that it was only one strip. I figured that, fine, I'll just do the front wheel, make it easy, and then order a second because these things are supposed to be so good. Well, cleaned the rim with ETOH, put in the rim strip, and cursed like a sailor finally getting my Gravelking tire on, also mangling my Pedro tire lever in the process. I've had those things for years and probably need to buy new ones now. Put in 60mL of Stan's sealant and hook up my Milwaukee m12 inflator...and nice, hear the bead seat. And all seemed good. Shake the tire around creating a new white boy dance and left it for the night. Come back after work the next day, and my tire is crying. Not blood, but something that looks like another substance that I can't mention here. Also tire is pretty much flat. I clean up that disaster, add about another 20mL of the other bottle of Stan's that was meant for the rear, do the dance of my people, and leave it. Next day, same story. I say screw it and buy this kit. Right off the bat, use it on my rear tire. I do a double layer, because I'm extra cautious now. Getting the tire on felt like a privilege in comparison. To the point that I was worried that I did something wrong. Squeezed that bag o' sealant in like a Capri Sun and commenced the jiggling. Next day...perfectly fine. Pressure was a little low, but that's supposedly normal. Topped it off. Next day...a couple PSI loss. I guess that's just the nature of tubless for some setups, but at least it holds. Next up, stripped the front tire and had a fun time cleaning that mess up. This time, I just did the recommended once over with like 6cm of overlap. Exact same outcome as the rear, except getting the tire on wasn't making me contemplate everything like before. It's only been a week, so I don't know if I'll just have to top off the 2-5PSI or so a day loss forever, but I've also not been able to ride it during this process. Hopefully, over time, sealant will work harder into the nooks and crannies. There could be better things out there, but this kit was a MASSIVE step up from the Trek/Bontrager offering (who I always settled with for being decent). Now I need to see if Trek will refund a mangled and gooey singlular rimstrip that cost me nearly the price of this entire kit when it was on a sale.

Bike: gravel bike running at 50psi in 60psi rated tires The pros It was easy to install. The cons: Man, where to start… After using this this boxed setup for 2 months I have been extremely disappointed. I have had several issues getting a good connection with the valve stem and my floor pump causing my to bring out an air compressor instead and hoping the air leaking out is less than the air going in. This is minor compared to the next issue I have had… I have included pictures of the product not sealing a small puncture hole on my bike. This is the 3rd ride and after the puncture hole and the 3rd time it has made a big mess out of everything. I can understand the first time on a ride but every subsequent ride is something that is not acceptable. This has cost hours of cleaning and trying to get things out of the chain to not cause further issues. This is the part where the product does not work. This was my first and last time trying Mucoff. I have used other tubeless brands in my mountain bike and have never had this serious of leakage especially continuing on every ride after.

did exactly what I wanted and their videos give you plenty of tips and instructions for converting your tires. Maybe an hour of work total to pull the wheels, do the install, and reinstall the wheels. It was basically mess free thanks to the application bags for the sealant, so that was a nice plus. They give you stickers though for keeping the end of the rim tape down and I didn't have any luck with that working the way it was supposed to, the sticker peels up way worse than the rim tape. Maybe use another little piece of rim tape to go over the end instead? I dunno, we'll see over time.

Add some content to help troubleshoot air leaks esp from the valve

Ottimo prodotto!

excellent rien à dire de plus

Mise à jour du 29/02/23 = gros problème avec une des 2 valves lors d'une sortie. Elle s'est rompue à sa base au bout d'un mois d'utilisation.... J'ai changé les 2 dans le doute. ------------ Le kit est complet pour convertir les deux roues de son vélo. Il comprend 2 tubes de préventif, du fond de jantes (une bonne longueur, il y en a peut être même assez pour faire 3 roues !) et les 2 valves presta, démontables, avec plusieurs joints de différentes formes (+1 bouchon supplémentaire). Rien de bien difficile à faire soi même, quelques conseils sont quand même bons à prendre. Pour ma part, c'était mon premier montage Tubeless, j'ai profité d'un changement de pneus pour faire cette conversion, avec succès (testée et approuvée dès la première sortie vtt). Bref je suis très content de ce kit, et surtout du fait qu'il est complet.

Le kit est complet simple de montage.
