The tires themselves are not heavier, it's the wheels that needs to be heavier.
In terms of rolling resistance tubeless IS the BEST.
This is 100% wrong.
25c Schwalbe Pro Ones are IRO 260g.
Tubeless valve - 7g each
30ml sealant - 30g
Total - 297g
11.0w rolling resistance
25c Continental GP4K IRO 215g.
Super light latex tube - 60g
Rim tape - 5g
Total - 280g
10.6w rolling resistance
And as for tubeless wheels weighing more than non-tubeless, that is also incorrect.
Thank you for your input.
You compared one SPECIFIC tire to another SPECIFIC tire, and jumped to the comparison that tubeless are worse in terms of both weight and rolling resistance compared to other systems. That just hilarious.
Even then, you are still wrong. The best tubeless setup is vittoria corsa speed open tlr. 225 grams and roll at 7.7 watts.
On the wheels side, wheels are now generally tubeless and tubes conpatible, back when tubeless just started, rims designed for just tubes are lighter.
As far as weight goes, all parts on a clincher is rotational weight, on tubeless he sealant always stay at the bottom. Effectively, it's a lot lighter.
You are full of absolute shite.
I compared the ‘go to’ tyres for many choosing either clinchers or tubeless.
The Vittoria is a fragile TT tyre that wouldn’t stand a chance on 99.9% of roads, essentially a track use only tyre.
And your physics chat about rotational weight is hilarious.
What about the internal friction and drag the sealant has on the tyre? Please explain that one to me in layman’s terms.
FYI, I’ve been running tubeless for years as well as traditional clinchers and tubes.
Hahahaha, you say that vittoria is a fragile TT tire, what about those 60 gram latex tubes then? Hahahahhahaha.0 -
I'm afraid, Andymaxy, you're hypothesis are just not credible. I'm sure some of what you say is true but it seems to be based on beliefs rather than facts.0

If the result of some (many? most?) punctures is a slight loss of tyre pressure that doesn't affect the ability to finish the race, tubeless has potential to become the first choice for sprinters and classics riders.0

If the Mavic guff about the design of its ust rims is to be believed, there is a design feature which stops deflated tyres rolling off the rim. If that is the case, and if a deflated tyre can be ridden on for a while then one of the tubulars outstanding benefits may no longer quite the USP it is now.0 -

I'm obviously attempting to have a conversation with a full blown cnut-tard.
Not sure about you, but I run my latex tubes INSIDE my tyres which generally seems to be the norm...
I've never had any problems installing them or riding on them. This includes descending Madone at 80kph+ which has numerous switchbacks and heats the rims up nicely.
I shall let you do you and I shall do me.
Just don't go spurting out incorrect and ill informed information to others, you're not really helping there.0 -

At that point it doesn't matter. Weight matters only during acceleration. When you are slow, and trying to get up to speed that's when you need light weight the most, and that's when the sealant is sure to be at the bottom of the tire. Once you are up to that speed, the weight doesn't matter anymore.
This is 100% true - until you ride a road race, or a crit, where you have lots of changes in tempo and you're up and down the cassette. Then the weight does become a penalty0 -
