Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Link please?

I just searched on eBay for 'powder coating masking tape' and chose the one which looked reddest. It's all basically just polyester adhesive tape. I think this may have been what I ended up getting.

Thanks! Does red tape make you faster?

Tesa tape has done 4 wheels today with stan's race sealant.
2 x terreno wet (tubeless) on iron cross
2 x hypervoyagers (not tubeless) on ryde dp comp

Who knew that doing things properly rather than in a rush gets resultS?

The one I last bought and used was this:

What's the verdict on the current Challenge road range?

Does red tape make you faster?

Fo sho. Red is always fastest. Scientifically proven, that.

Red shift is a science thing, checks out.

After an hour of googling, I can't find an answer, so hoping someone here may take pity on me -

Just got some wheels off ebay which come fitted with tubeless tyres, which is brand new and scary to me, but seems a shame to get rid of them and go back to tubes.

Problem is the tiny screw/nut at the end of the valve (to release to allow to be pumped up) has seized on both wheels. I think I need to replace the valve core(?) If I'm lucky, can I do this without unseating the tyres? I don't fancy my chances of getting them back on. Also, are all valve cores much of a muchness??

May be way off the mark here, so apologies for ignorance

Thanks

Yeh happens all the time . The latex gets stuck and eventually plugs. Take a pair of pliers and take the core out if you dont have the remover tool . Do it with the vale at 12oclock obviously .

• Maybe, but I find they often unseize if you take them out and fiddle with them
  
• Probably
  
• I think so. I've used both new valve cores and ones salvaged from old tubes
  

Thanks for the advice. Can I do this and keep the tyres seated? Or will I need to start the whole process again with new sealant and an air reservoir pump (which I don't have unfortunately)

Depends. The beads may pop off the rim bed. They might not. Some tyre/rim combinations will reseat with just a track pump anyway.

I think the best thing to do would be:
Buy some Tesa tape
Buy some sealant
Buy or borrow a sealant syringe
Borrow a track pump and airshot
Take everything off
Retape
Mount tyres
Throw sealant in tyre

Do it all at your mates house as well. That sealant will go everywhere . For now beginners luck if the rims pop or not.

Can I do this and keep the tyres seated?

Yes, if they're properly designed. If the tyres fall off when the pressure drops to zero, you might as well just fit inner tubes.

I just did exactly this after the valves gunked up on my first pair of tubeless tyres.

They both stayed on the beads throughout.

Made my mtb tubeless yesterday. It went really easily.

Maybe luck, maybe combo of wtb rims and wtb tyres, maybe mtb tubeless stuff is just a bit better?

The bike is a Kona Unit, surprisingly the wheels were taped with tubeless tape from the factory.

maybe mtb tubeless stuff is just a bit better?

Not so much better as just easier. Road tubeless would be simple if road bikes used 50mm tyres at 2-3bar 🙂

I might be eating my words today anyway, rear had lost a fair bit of pressure overnight.

Seems to be coming out the joint in the rim.

Have sloshed the sealant around and tried to leave the wheel so sealant would be pooled in that area so we will see.

if its holding enough air that you only notice it losing pressure overnight try riding it, might help distribute the sealant.

I've always had better luck with MTB stuff personally, tyres going on more easily and staying in the bead better.

Yeah I should have tried to get out on it today but ran out of time. The sloshing seemed to have helped. Will check again tomorrow.

Got smug with helping set up @monkdagola grave wheels yesterday. Terravails on Hope both went up first time with a track pump.

Yup. The higher pressure in road tyres means all seals have to be better, while the lower volume of air means any loss is more noticeable. Higher pressure also makes it harder for the sealant to do its job; c.70 PSI is apparently the cut off. I'm not anti road tubeless, just a bit sceptical that it offers any real advantage.

I'm anti road tubeless.

I would take the time to sort it out properly. If you get a puncture while you're out and you end up needing to fit a tube, you'll be glad you did.
