I bought Schwalbe Doc Blue 500ml. It comes with a smaller 60ml bottle.
On my road bike I put 30 ml in each tyre.
I refill every three months or so. Although if I have a puncture that's sealed - I had one which sprayed sealant before it sealed - I top up.
I run at 75/80psi. I did 60km on the Waterford Greenway at about 60psi, using a handpump after the puncture described above sealed. I had no problems at 60psi. Rolled fine.
I changed tyres using my normal tyre levers though there are tubeless specific ones for sale.
I used a Giant Control Tank along with my track pump to seat a tyre. I found the pump wasn't sufficient.
Yes to your last question.

Cheers, thank you for those responses. There are such a wide variety of options it is easy to get lost on what to go with.

Ordered a Schrader to Presta valve converter for the father in laws compressor this morning to have a go at a ghetto conversion on the MTB. I have PR2's on the commuter/ winter bike - might order enough sealant to have a go at that wheel set too.

Do people use the syringe injection to put sealant through the value?

Bottle with small nozzle

Should I get the large bottle (500ml etc) or just the smaller bottles? Larger are more cost effective but how often will I need it?

Get large and be done with it, small is too small

What level of sealant is required in each wheel?

30mm

How often is sealant required to be reapplied?

Told by wheelbuilder 3 months summer, 6 months winter due to it being colder

What sort of pressures are people using on tubeless on the road?

75 front, 80 rear for about 80kg weight

Is it necessary to get better tyre irons based on the harder to put on tyres?

If your tyre goes on easily I'd say no, if its a bitch to get on then buy the irons for when
you have to take it off

Is a track pump sufficient most of the time to mount the tyres?

Based on the 2 rim types I've tried I'd say no

Can normal (ie non tubeless with tubes) be used on tubeless rims?

Yes

guess it all comes down to the tyre/rim combo. So far been no problem for me but reading above a nightmare for others

Do you ever need to clean out the old sealant from the tyre? Or does it just go to dust?

Great , let us know how you get on. The MTB should be fine, I'm wondering about the PR2. I read bits and pieces on the internet to suggest that they work tubeless.

I was out today talking tubeless tires with my fellow roadies. I was explaining how a tube can be fitted to tubeless tires to get you home in a bind, but my confidence and expertise quickly folded under questioning!

Specifically - how do you remove the existing tubeless valve stem. Am I supposed to carry a wrench or vice grips or something to do that at the side of the road or is there a trick to it? - I'm running mavic ksyrium Elite UST's..

Hi

Can i ask if anyone is running giant tubeless Gavia tyres? How do you find them?

I think grip is poor in wet conditions, i don't have much confidence in them. These are 25mm tyres.

A while back i ordered 28mm tyres hoping grip will improve in the wet. 28mm may slow down performance though

Be nice to hear how others are getting on with gavia

My knowledge is all theoretical (although I'm in the process of switching to tubeless). One school of thought is that you should never need an inner tube (https://thecycleclinic.co.uk/pages/tech-page)


The other is that the locknut for the tubeless valve doesn't need to be overly tight - the first link above suggests otherwise...

I've got a bike with them. They've been better than I expected but I'd imagine that other manufacturers make a better tyre. I'm planning to swap mine out when I get more time but for the moment they're fine. I found that I had to reduce my tyre pressures by 10 psi front & back for them to feel in any way decent. I'd suggest that you have a think about your tyre pressures and if that doesn't work then look at a better brand like the new Hutchinson Fusion 5 Performance (https://roadcyclinguk.com/gear/revie...e-review.html)

Much the same as an ordinary tube. There is a nut which you unscrew on the outside and then you just push it out

That's the thing though innit. After 12 months of elemental exposure, how easy will it be to loosen that nut in fading light up the Sally gap

In that regard its no different to any other screw head or adjuster on the bike, you need to check every now and then that they still move. I don't do it myself but a quick check every time you pump up the tyre wouldn't go astray

Question guys. Recently replaced rear tubeless tyre and filled it with sealant. Topped up front tyre as well while at it.

While the front maintains the same pressure for days the rear acts like a latex tube... it lost pressure over a couple of days. I added more sealant and it helps but it still loses pressure over a few days.

Could be just a case of adding even more sealant but any ideas ?
