    Tips and Tricks for setting up tubeless

    This is my first go with tubeless setups and I spent the better part of 2 hours trying to set up my new wheels last night with a 50% success rate.

    Rims are WTB Freq. i23's and tires are a WTB TCS Moto (F) and TCS Bronson (R). I am using a Lezyne Dirt Floor drive, which claims capability to seat tubeless tires. Well, I got the rear set up with moderate difficulty, but this morning it was still holding air. But for the life of me, I cannot get the front to seat. I also had a lot of difficulty with the rear and think its sheer dumb luck that I got it to do so.

    I've read the stan's instructions, read those provided by WTB as well as whatever I can find on the web. Anyone got any specific pointers?
    Alcohol may lead nowhere, but it sure is the scenic route!

    soapy water around the bead has worked for me.... but so has a compressor when I wasn't able to get it.

    Old tyres with a stretched bead are harder to get a seal with. New tyres are much less hassle.
    Try pulling the bead out toward the rim edge to reduce the amount of air getting between the bead and the rim.

    If you are using a valve with a removable core, do this (assuming you've taped up your rim and installed the valve properly and you have a compressor):
    1. Put the tire on the rim on one side
    2. Put sealant in.
    3. Put the other bead on and make sure that both sides of the bead are set correctly
    4. Remove core from valve
    5. Put blowgun attachment on compressor.
    6. Shoot a blast of air into the tire (the higher volume of the blowgun is the secret in setting the bead)
    7. Put finger on the valve so all the air doesn't come out and reinstall core.
    8. Check for leaks.

    I've set those exact rims with those exact tires up with no issue using a cheapish Topeak floor pump.
    Lots of soapy water on the bead. Bounce the tires on the ground a little and squish them with your hand against the rim (straight down).
    Try and get the bead out of the channel and onto the ramp.
    Then when you're pumping have the valve at the top of the rim and push the bead tight AROUND the tubeless valve.
    That's probably where you're failing. It was for me until I figured out that trick.
    If you just get a decent seal right around the valve you'll be able to air up the tire.
    Pump like a demon possessed (yep one handed, one hand pumping and one holding the bead on tight around the valve)

    Or you could probably skip all of that and use an air compressor.

    Let me know how it works out for you.

    4 years running tubeless and I never heard of a blowgun attachment before.

    Doh!

    I have 5 bikes (3 mtn + 2 road) all mounted tubeless, all conversions, all set up and holding air since last season. But the next time I mount a tire, I am so going to Home Depot and dropping a mere $5.00 for a blowgun.

    Great tip

    You may want to consider getting a compressor if you're committed to running tubeless. I use a battery-powered portable Ryobi that I got from Home Depot equipped with presta adapter and it seats tubeless just fine.
    Please donate to IMBA or your local IMBA chapter. It's trail karma.

    Thanks for the suggestions. I ended up just going to the LBS and using their compressor. So far after 48 hours, they are still as firm as they were initially. No leaks, no seeping of fluid, nada . . . I think we're good to go!

    let me know what you think of the Bronson rear and Moto front.
    I'm running the reverse and really like them.
