Tubeless curious

I finally got round to fitting some Schwalbe One Pros today. It was pretty painless, compared to some of the stories I've read. Tyres went on without any swearing or need for tools and I was able to get a seal with my track pump.

One quick noob question. Do I need to keep the valve stem nuts on to maintain valve seal integrity? I'd prefer not to. My worry is when I fit my pump the next time I might push the valve in and break the seal.

They need to stay on, otherwise the airtight seal will be broken.

Thought so. Thanks Andy.

Take em off and use bubble gum

Sugru!

I use tubes to maintain valve seal integrity. Seem to work well.

I had my first non-sealing puncture today, on the way to the club run. I was supposed to be leading, but had to abort.

I am a bit disappointed at how small the hole is. I suppose a 3mm Putney High Street glass gash is asking quite a lot though. I used up valuable CO2, optimistically trying to re-inflate after the hole appeared to seal.

I tried putting a tyre boot in (just in case), but it wouldn't stay in place due to sealant. It wasn't required really, although if it was, I would be a bit stuffed.

The main issue was trying to get the inner tube filled tyre to re-seat correctly when using a hand pump. It took 2 attempts with the track pump at the cafe in the park. By then, I'd waved goodbye to the club run.

Besides the obligatory "Throw them away and get proper tyres", any advice on what I can do to get the tyres (with an inner tube) seated if I don't have gas or a track pump.

This is not convincing me to make the jump.

It's the 'when the go wrong, they go really wrong', problem that worries me.

I love the Schwalbe Pro Ones. They ride and behave better than any tyre I've had before.

@hippy I think I'd have been OK if I'd had another canister of gas.

You can't pump a just sealed tubeless with co2. The pressure breaks the seal. It wouldn't've mattered if you'd have had another 50.

I don't use CO2. So that'd be something else I'd have to worry about. Once the canisters are done you still need a pump.

So you need a pump still?

You need a pump or 24 hour wait. You choose.

Tubes :)

It was not just sealed. It was just fitted with an inner tube on the side of the road. The issue was getting the beads to pop into position. I ended up with some bits fully popped, and others still sitting too far inboard. A quick burst of CO2 usually does the trick.

Aren't these just teething problems? I'm not tubeless yet, but there's often an issue getting used to the technology you're using. Burping, sealing, all those things, are often discussed in the cross thread...

I have no advice. But I'd just like to say... LOL.
'its the future'.

Pretty much this.

Tubless curious riders are banned from the BCM by the way.... Just sayin.

Is getting the occasional puncture with regular clinchers that big of a deal? I probably get 2 per winter.
If you use decent tyres, look after or replace them before they're shot and keep pressure correct you very rarely get punctures. Just doesn't seem worth all the faff.

I had two regular punctures on the way to work today. Front and back.

Double flat, brakeless fixie is scary-wary

has anyone experimented with tubeless sealant in normal inner tubes? Pretty sure it can do the same job of sealing small holes.. Obviously wouldn't fix a nail though...

I think this has been discussed on the other place, by howard (god of tubeless), i think the takehome message was "worst of both worlds".

I think MTBers have done that with normal Maxxis tyres. Think that has worked ok (although they're tougher than road tyres).
