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

Yeah, logic would dictate squirting inside the valve would be easier and less messy

Now why didn't I think of...oh wait I did :)

Science friends are useful for procuring that kind of stuff.

My 25c Schwalbe Pro-One tyres are almost 29mm at ~ 70psi on a 20mm internal width rim (SL23 v2). Does anyone know how wide the 28mm version of the 2017 (herringbone tread) IRC formula pro RBCC comes up at the same pressure on a similarly sized rim? Thanks.

I have a 28mm Pro One mounted on a Light Bicycle U 65 rim (https://www.lightbicycle.com/65mm-deep-carbon-700C-25mm-wide-road-rim-clincher-U-shape-tubeless-compatible-with-high-TG-resin-surface.html) that I could measure tonight?

Thanks very much for the offer hippy, it's appreciated, but it's actually the 28mm IRC formula pro RBCC that I want to know the width of. They're comparatively rare, so I know it's a bit of a long shot...

pretty excited about the set of Schwalbe 700x30 s-ones that will be mounted on some prime pro disc wheels tonight, gonna be like a motorbike!

had some issues with CRC sening the right wheels, but a combo of a nice guy in customer service and evans having some centre lock rotors in stock means I'll be rolling by the weekend!

Any reason I can't take the Schrader valve core out and quirt 30ml of sealant into my Brompton tubes? Fed up of rear punctures.

Sorry, I only own the Schwalbe Pro One. @cycleclinic might be more use?

I've heard of people using sealant in tubes and I know you can buy pre-slimed tubes so I see no reason not to give it a shot. Can you not buy more durable tyres for Bromptons?

How many have you had?

In two years of ownership I never had one, Paddington to Holborn 2x per day, with the marathons.

time for a new tyre?

Yeah but they're slow and I've already got sealant.

4? All from glass in the tread on the rear. Standard Brompton rather than Marathons. Should probably spend more time pulling out the shards tbh but cba.

answer = buy marathons

the amount of time wasted changing a Brompton rear tyre once will negate all the savings made in rolling resistance between that and a standard tyre...

4 times, and you may as well just walk...

they're slow

Brompton.

GTFO >>>

Cheers Hippy. The answer from @cycleclinic was 27 - 28mm.

answer = buy marathon pluses

FTFY. I love the sound of crunchy bits of glass under my Marathon Plus tyres first thing in the morning. Ride quality's abysmal, but life is too short for fixing punctures on a Brompton.

And I know @edscoble will claim that fitting Marathon Plus tyres will make your Brompton explode in a fiery ball of death (until they changed the sizing) but mine hasn't.

Latest Marathon Pluses have addresses the sizes issues and now compatible with the Brompton.

I knowes. That's why I said 'until they changed the sizing'.

I Would be interested on the measurements, if you can measure it up.

I can but it won't be until tonight, probably tomorrow.

Does running tubeless on a turbo trainer make any noticeable difference?

My turbo likes to be clamped hard so if you have to run tubeless at lower pressure I wonder if there's any issues? Probably throw my calibration off to some extent but that can be fixed.

Y u no turbo tyre?

Sure thing, thanks mate!

Is seepage normal? And yes I'm talking about tyres. There is a very small amount of liquid coming out where the bead meets the rim, negligible, but thought the whole point was there was a seal?
