Sun Ringle Mulefut 80 SL Tubeless Tape 78mm Wide 10M

Fat bikes benefit greatly from tubeless, perhaps more so than any other type of bike. The Mulefut rims are the first relatively affordable fat bike rims that work really well tubeless. Mulefut rims have a fairly high bead seat and a fairly agressive bead lock lip. There are many way to make Mulefut rims tubeless but none is easier or more reliable than buying this tape. As the Mulefut rims have holes in the beat seat, you need tape that runs exactly bead to bead. This tape is the perfect width to cover the entire rim bead to bead and plug the holes in the bead seat without excess tape. Also, this tape won't absorb sealant like Gorilla tape and is much lighter than Gorilla tape. I set up my bike as tubeless fairly easily the first time using this tape and the SR rim strips. It was easy as far as tubeless conversions go. My advice: if you have Mulefut rims just pay for this tape, don't try something non-OEM. People may have moral qualms about paying $25 for 30 feet of tape but this stuff works really well and you're likely going to have problems if you try to use something else. Make it easy on yourself and buy the tape.

After cleaning both SunRingle MuleFut and Surly Rims, I installed 3M reflective tape and then put this Rim Tape over the top. Used finger pressure to smooth out as I went and after wrapping, used a hair dryer to smooth out and press down to get rid of any creases or bubbles. Installed tubeless valves (Muc Off) and then put on tires, seated them with air pressure, removed valve core and put in sealant and inflated. No leaks anywhere. Fat Tire rims are notorious for leaks with the cutouts but the tape held perfect. Heard issues of folks not getting adhesion. No issues here. Simply clean your rims and put on slowly with pressure and you are good. Will use if I ever have to replace.

All the reviews that claim this stuff doesn't stick... BELIEVE THEM! I would go a step further and say it is also too narrow. In order for this tape to work, it needs to be as wide as the outer dimension of the rim, so that when it is pressed into place, the outer edges are up on the inner side wall. This guarantees a seal between the tire bead and the tape.The other issue is with the rim itself. The rim strips suck. They bulge out too far under pressure as there is no fabric reinforcement in the material. What this does is cause wrinkles to occur in the tubeless tape and if these rinkles reach the edge of the tape it's a wasted effort. Sun Ringle should really have this stuff factory installed, like ever other tubeless wheel set out there.I have a feeling that people are relying on tons of sealant to get this stuff to work, but this represents a failure of the product. Use duct tape for the rim strip (see pic) and gorilla tape for tubless tape. Done right you should only need 4oz of sealant for a air-tight tubeless setup.

I have tubless ready Sun Ringle fat tire rims. My first attempt at tubeless conversion was with Gorilla tape. I never got a good seal. I decided to purchase this tape and with a helper, we got a great airtight seal on the first try. Follow the directions by cleaning, degreasing, and overlapping according to instructions. This is wide, so a helper is good to get great alignment on the rim. Very thin with good adhesive, so once in place, it stays well. Thin enough that it doesn't interfere with the seating of the bead. I did two 27.5 rims and have tape left over.

This tape is perfect for the 80mm Surly My other brother Daryl rims.The set-up/application of this tape was easy (I always use a Gorilla tape base first) and the tape Easily applied on the base layer. The Surly Nate tires seated nicely. The tires are holding air and rolling perfect.

After 9 punctures in two rides (stupid goat heads) this tape worked well on new Mulefut 80 rims following some tips found on this site and others. Cleaned rims well, used two wraps of Duck tape sticky side out, applied tubeless tape, inflated with tubes and let set overnight for good adhesion before going tubeless. So far, so good.My only complaint is that I ordered it thru Amazon and waited nearly 2 weeks before finding out it was never shipped. Ordered it from another company and got it in 3 days.

Easy to use and provided good sealing. I haven't even put in sealant yet and the tires hold air for over 10 days (filled to 15psi and dropped to 6-8 psi after 10+ days)
