road tubeless

[rock]

who's running tubeless?

 

whats your setup? where did you buy your tires? Assume you're running Hutchinsons?

[Jonkie]

Ksyrium elite's with Scwalbe ultremo zx tyres. 90–95 psi back 80 front. Ride quality amazing. Tyres expensive but I doubt If I will be able to go back to normal setup.

Forgive my ignorance, but what are the benefits of tubeless on road?

 

I know on all my MTB's I run tubeless, so that I can run lower pressure for more traction...

 

Same thing for road?

I'm running the new American Classic rims with Hutchinson tyres .

Rims are local tyres are from Wiggle .

Ride quality is easily equivalent to my Firecrest Zipp's but the wheel set is 500 grams lighter .

My other set is 404 clinchers

I agree Wayne , Sorry been there , the sludge is to thin to seal that tyre under that pressure , If they design sludge that can seal that tyre under that pressure Id might reconsider ,My opinion

Serious question....

 

Is it to reduce flats or save weight?

 

I really don't understand.

 

I spend all my riding time on a MTB my road bike is only used on a trainer.

 

I was just wondering about the reasoning behind it.

Supposedly it saves a little bit of weight and can reduce flats.

 

I think the main reasons are similar to MTB: lower pressure = more compliant ride and better traction.

As far as I know on a road bike , The higher the pressure the better , thats why 99% off the pro riders run tubbies , because some tubbies can be pumped to 14 bar Edited June 18, 2013 by Sani

Thanks.

 

I would have thought you would want less of a contact patch as it surely reduces road friction?

[NotSoBigBen]

If only for hopefully less punctures I would look at it ... at such high pressures I surmised the sealant may not be as efficient though?

It'll never be at MTB lower pressure, but running a setup at 80-90 psi can be much more forgiving than 110-120 psi.

 

I personally don't do tubeless on a road bike, I dont think it's quite there yet. Maybe in the future it'll become the de facto standard as it has (probably) become in MTB.

 

Also, wider contact area has been shown to have lower rolling resistance, which is why pro's are now riding 700cx25 instead of 23.

That's interesting...I would've thought otherwise.

The pro's ride tubbies for a whole host of other reasons that high pressure though:

Lighter rims, increased puncture resistance, no more pinch flats.

 

Higher pressure means less rolling resistance and increased puncture protection, at the cost of comfort.

110 psi, no shocks and RSA roads.

 

Perhaps you roadies are tougher than I thought.
