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

Anyone done Crr measurements on Fusion X-Guard or RBCC (what's RBCC?).

Ah, this is RBCC "rice bran ceramic compound" dafuq?!
http://www.velodistribution.co.uk/product/irc-formula-pro-rbcc-tubeless-road-tyres-28mm/
25mm tyre 275g (20g heavier than Pro One, 50g heavier than GP4000Sii)
28mm tyre 320g (heeeeeaaaavy!)
RRP £50 (spendy)

No point using long lasting tyres if they're slow though. I could just ride Duranos or Marathons for 20,000k. I assume Pro Ones are faster than RBCC tyres? The rolling resistance site has only tested an XC IRC tyre.

I'm 88.8kg. Bike is ~18kg. I had no issues with tubes last year.

I don't think you can get tanwalled tubeless tyres, the tyre construction method precludes it.

Wtb Horizon? Perhaps not a true gumwall, but what is these days apart from Veloflex

@cycleclinic if you've got loads of syringes would you mind sticking one into my package please? Not quite sure what type I'd be looking for...

Cheers!

"Pretend" is fine, I'm only after the Instagram likes

I'll be selling my horizons soon if you want

Yeah you can Onza Canis / ibex or Compass Steilacoom for example

You can easily run the 700c slicks tubeless on most tubeless rims.

you could go for these: https://sim.works/collections/simworks-by-panaracer/products/volummy-700c
basically tubeless skinwall 32mm gravel kings.

if you're looking for some more tread you could go for these, I've been running them tubeless for months now: https://global.bluelug.com/fairweather-for-cx-tire-by-cg-black-skin.html

and of course the slightly bigger: https://www.compasscycle.com/shop/components/tires/700c/compass-700cx35-bon-jon-pass/

60ml catheter syringe. Befriend an old person.

Will you be my friend?

700c Horizons?

I can't actually find any online at the moment, confusingly.

his are 650b

They all are, I think.

@Dammit The 700 Simworks are pretty new, @radbikesNX on Lewisham Way have just announced they're going to supply Simworks stuff in London ... haven't been in since to see if they have any stock yet.

Are you passing anytime soon? If not I'll call them tomorrow.

they are not slow. i have a race team on the RBCC tyres. riders keep on winning.

there wont be much in it between the pro ones and the formula pro IRC tyres tyres. i suspect the pro one will have slightly lower Crr but it could be the other way around. there is nothing slower than a flat tubeless tyre. On a bike like your hippy this is the danger witht the pro ones. they are a race tyre and a mean a road racing tyre not a loaded trip accross a continent race tyre. there is always a trade off. for ultimate pace use the formula pro light (more like the pro one but with better durability) but i would not use these for a continental race either.

i ride a 18kg bike they tyres work on this and those mileages were done on this bike mostly through winter.

weight of a tubeless tyre is roughtly equivelent to non tubeless tyre and tube there is not alot init.

well i bought loads of syringes i am not sure where they all are now.

thanks for reminding me i need to update the B2b now i have tyre stock again.

Yes, I guess weight is similar once you have accounted for sealant, and unlikely to be a primary reason for switching to tubeless.

Consider the Schwalbe 'Pro' range:

• For a 28c tubeless (i.e. Pro One) it's 2 x 275g = 550g
  
• For a 28c 'normal' + tubes (i.e. Pro) it's 2 x (245g + 105g) = 700g
  
  

I imagine that sealant would use up some of that 150g difference.

And the valve...

sealant is about 100 grams for road tires.

Stans produces Schwalbe Doc Blue Professional.

This page says

Dose: 60 ml/tyre (Race bike 30 ml)

So how dense is sealant?

Yeah, good point on the valve. I thought about that after I had posted. 10g each?

So, for a 28c tubeless (i.e. Pro One) it's about 2 x (275g + 50g + 10g) = 670g

sealant is about 100 grams for road tires

Try using a bit less 🙂
I weighed my 25C Pro One installation complete with double tape, valves and a generous portion of sealant and it still only came to 80g for the pair over the raw tyre weight.

after setting up about 7 sets of road tubeless tyres, 30ml doesn't cut it. I always add some after 3 weeks.
