• So bought the lifeline pump:

    Trying my hand at setting my pro ones to my dt swiss 1400 dicut rims. but no joy in seating either bead. I read some people don't even put sealant in until the rim is bedded in. Is it possible to push one side of the bead into the rim? put some sealant round the sides of the rim to aid sealing but that hasn't helped.

  • Have you got the tyre completely onto the rim? If so, it's only critical to get the beads around the valve to fit correctly, the rest of the bead will pop into place as the air goes in (I use a regular track pump to do mine, such is the tight fit). Don't put sealant in until you pumped the tyre up for the first time, or else you'll be introducing your face to the sealant when it pops into position.

    FWIW, I heat up my tyres in hot water before mounting them first time, makes them so much more manageable.

  • Yes it fit over the rim nice and easy. And the bead is sitting right around the valve too.

    Thanks, I'll drain the sealant out and try that at least! Does the inner tube trick work well?

  • Does the inner tube trick work well?

    Probably, though I've never needed to use one. There's a reason they're called Tubeless Easy, it really is quite simple once you get your head around it. Just remember, once you have the tyre on the rim (as you seem to have), do the soapy water thing around the sides of it. This lubricates it a little, and aids it slipping into position once you inflate it.

  • Are you talking about these?

    From the look of it they look like they'll be easy to mount and lock bead on. Not crazy wide either. Is the tape ok? Soapy water?

    My Pro Ones went on HED with just a shitty floor pump .. and thats 19mm wide and not as 'modern' as that DT swiss.

  • Possibly put another round of rim tape on.

  • That's the one amey. Haven't done soapy water yet but put sealant around both sides of the bead to help seal. Will report back tonight!

    So no one normally needs to push to tyre bead in the groove manually?

    @dancing james will look at that if all else fails. I only took the tyre off to patch the inside so they shouldn't have changed.
    Thanks @finger_jockey

  • Ah. Have you cleaned all the old latex gunk of the tire bead? Because that will stop it seating also (leaving the gunk on)

  • Had a miserable time over the weekend trying to setup my Genesis Longitude tubeless. All parts are tubeless ready WTB scraper i35 rims and 2.8" tyres. I was using 40mm WTB tape and Stans valves. The tire sat on the bead very easily with just a track pump, but I seem to be having a lot of leakage through the rim. Sealant was coming out the spoke holes and in some cases the nipples.

    Is there a trick to setting the rim tape. I was struggling to get the tape to be tight when sticking it down and getting it to conform to the well of the rim. On one attempt it ripped when I pressed down on the center of the tape as it isn't stretchy.

    Any tips?

  • Any tips?

    You can be fucking shoddy with gorilla tape and it works. Tape can be so wide it goes up and over the side wall. The yellow tape is much less forgiving - rim has to be very clean, and application has to be very accurate, and as you have found, it doesn't like being stretched.

  • In terms of width WTB says rim width plus 5mm (I guess to take account of curvature of rim well). With gorilla are you aiming to cover simply the spoke holes, or take it right up to the edge of the bead hook?

    Would yellow tape be better if I left the inner tube in there overnight say to help set it?

    but no joy in seating either bead.

    So the air is escaping from somewhere. This is usually around the valve core. Double / triple check the tyre bead is sitting on either side of the valve hole - by default one side tends to sit on top of the hole, and you lose the air, and you can't inflate the tyre.

    I've found compressing the tyre with your palm over the valve hole when you inflate helps create a weak seal in this area and it's usually enough to get the tyre to go up. This is after dicking around with a tyre leaver to get the bead in the right place on either side of the valve hole - note in the right place, you can't seat it manually.

    I read some people don't even put sealant in until the rim is bedded in.

    Through the valve core with a syringe is the least messy way of getting that shit in.

    Is it possible to push one side of the bead into the rim?

    With an innner tube, yes. mount tyer with tube, inflate tube, deflate tube, pop bead on one side and remove inner tube.

    put some sealant round the sides of the rim to aid sealing but that hasn't helped.

    Yes this won't help, will just make a mess.

  • I'd say with any tape you are aiming for it to be butted against the sidewall, because when the tyre deflates, if it's not sitting on tape, it's going to take the tape with it back towards the centre channel.

    These days I just bung some super wide GT in it and don't care if a bit of tape is sticking out of the tyre / rim interface when the whole thing is done. It just works. So bascially just cover the entire rim surface with that shit.

    If your yellow tape has got sealant under it then I'd either remove and bin it or get some GT and stick it over the yellow tape.

  • Seeing as I have the yellow tape, the plan is to
    a) remove yellow tape and clean rims
    b) apply new yellow tape
    c) Leave innertube in overnight to help set tape
    d)remove one bead and tube, install valve
    e) pump up hope for best - if not weezing like mad from nipples go ahead and add sealant.

    If I do end up going with GT do you mean the classic black stuff or the clear repair tape?

  • Last set of rims I did - WTB I25s

    Removed tyre - Nobby Nick TLE Performance 27.5 (eeccckk!) - removed tube
    Removed rim tape - was a crappy plastic strip
    Waved a baby wipe over the rim bed, I think there was some contact, but can't be sure
    Slapped some 35mm wide gorilla tape down with a spot of doubling up over the valve hole
    Cut a valve stem with removable core out of a busted inner tube , popped it through the tape to make a rough hole, then fitted it with the lock-ring hand tight
    Popped the tyre back on - didn't need leavers, never a great sign
    Hit it with the Bontranger Charger pump at 175psi, and bosh, inflates first time. Remove pump and air escapes through the empty stem
    Added Stans through the valve stem
    Popped the valve core in to the stem
    Re-inflated
    Rode bike

  • May well have been getting it wrong with the valve then! Thanks a lot @Howard

  • Popped the tyre back on

    You were doing really well, up until then.

  • Still no joy with it! More playing around tonight. Will resort to using a tube to seat one side.

  • What's not happening?

  • Saw that on a video I found today! Might see if I can pick that stuff up.

    Cheers.

  • It's just washing up liquid and a sponge.

  • It's premium washing up liquid bro, premium

  • I mean what problem is that shit even trying to solve?
