Tubeless or not?

I have just taken delivery of a new gravel bike. It was built to order and I specified that the tubeless ready wheels should have tubes installed.

Is there any way of confirming that the wheels are tubed just by inspection?

I don't want to unseat the tyres unnecessarily.

    The shop will say they provided what I ordered. However that would also have been the case with the MTB I bought a few years ago and which was provided tubeless when I ordered tubed.

    I found out a few miles from home when I had a puncture which did not self seal. (I had a nasty off & injury which resulted in the MTB sitting unused for over 6 months by which time the sealant/gunk had set in the bottom of the tyre.)

    Would the type of valve tell you whether it’s taped or not.

    Tubeless will have threaded valve stem and lock nut tightened down. Tubed may not have these.
  • It depends, I would ask a local bike shop

    Post a picture and it might be clear one way or the other.

    Try letting a bit of pressure out of the tyre and remove locking ring on valve, if it pushes in and feels spongy then it's a tube. If it feels like it's stuck then it's probably tubeless.

    Good thinking Oxoman, cheers.

    what did the shop say when you called them?

    Stick a pin in it. When you pull it out if it’s followed by sealant it’s probably tubeless.

    Leave a wheel with the valve at the bottom for a hour so that any sealant pools at the bottom. Take the valve core out and poke a piece of stiff wire or something similar down the valve stem . If you can see any sealant on the end of the wire you are tubeless.

    I didn't call them given the logic in my post above.

    However I did try @oxoman's suggestion and I am confident that tubes are installed.

    Spin the wheel ,remove the core it will be wet with sealant .
    I would say if it was tubeless there would be core removers supplied with it too
