    Split Tube w/ 26" Tube on 26" Rim

    I have some difficult Surly tires that don't play the tubeless game well with my (26") Nextie hoops. Problem with the Nextie hoops is they are deep and need long valves, and LBS's only have larger tubes in 32mm valve lengths. Only tubes they had with 48mm valves is in 26x2.1-2.3. Will that work for split tube? I have always used 24" tubes in the past on other split tube projects with different rims.

    You might be able to get it to work, but expect a fight. I can see the tube wrinkling and making it difficult to get the bead to seal. If anything just buy one to try it.

    Maybe you can use presta valve extenders. I can't imagine any way that the 26 split tube is going to work - you really need the 24" tube to be stretched on there.
    I would advise not taking my advice.

    How about Fatty Strippers and use long presta valves?

    Maybe if you glue the split tube to the rim along both sides it wont wrinkle on you.

    I made it work (totally forgot to use 24"tubes)... There is a fold in one spot but it sealed. Ugly though. Too lazy to fix it.

    I tried once to seal a 29" Knard to a 29" Rabbit Hole with a 29" split tube. It was a no go.

    Which Nextie rim is this?

    I have two pairs of Nextie , one for the Fatbike the other for the 26 MTB , both are excellent tubeless rims. Been a Plug & Play experience with Bud & Lou.

    I use Gorilla tape.

    The Bud I have can pretty much be put onto the rim with little to no effort. Loosey goosey. I found that Surly makes a fat tube with a presta valve that is long enough to peek through the rim.

    The surly fat tubes are heavy and thick...
    If not in to much of a rush might be easier to order one online.

    32mm isn't long enough.

    I haven't tried this but it seems like one could cut a few inches out of a tube and use patch kit glue on the two ends to make it a smaller diameter split tube ... I guess one problem could be that the thickness of the overlapped seam could cause a sealing issue with the tire against the rim? Good luck!
