FrostBike 2013: Hands On with Schwalbe’s new Ultremo ZX Tubeless Road Tire

Nice! Now if they can just make one in a 25c version

Yes, really, the last thing we need is another 23c tubeless. let’s get some 25-28s going

Agreed….need more 25c & 28c Road Tubeless Tyres. And better mileage than Hutchinsons too…..

Chalk up another vote for wider tubeless tires please. But do the industry types read these comments?

Echoing calls for wider options, please. 25 and 28 in the same casing construction to start. Once 25s are available, I will never buy a 23 again for the road.

Yes, 28C please! Hutchinson, Bontrager, Specialized, Maxxis make 23C and 25C tubeless tires, but no one makes a 28c tubeless.

Too heavy! Conti Supersonics + tubes = half a pound less for the pair, without counting the rim strip, valve and Stans for this setup!

i’d settle for a 23 or 25c tubeless that actually measures how it’s lablelled.

Well the diameter is in millimeters too… so you just violated your own rule by saying 700C instead of 700mm.

Almost every bicycle tire manufacturer designates their tires in the manner 700x23C.

All: the “C” in 700C stands for “clincher.” They are 700mm wheels (measured with a tire installed, so you’ll never really get an exact 700mm diameter, but that’s the theory), and called 700C for clincher wheels.

Hashbrowns is right – tires are measured in millimeters. They are also labeled 23c or 25c, though, because they are clincher tires.

I hope you know how stupid you sound. Go read yr Sheldon Brown.

(700c tires are 622mm bead to bead circumference)

@mateo: I made no claim that C stood for cm. Perhaps a visit to your optometrist is in order.

@Johnny: The C doesn’t stand for clincher. Nor does it stand for cm.

@bob: Everything I said is correct, and you are the one that needs to re-read Sheldon Brown.

Let’s restate the facts. We are referring to tires which measure approximately 700mm x 23mm. The common nomenclature for these are 700x23C. You will find that nomenclature in nearly every manufacturer’s product literature.

Hashbrowns stated “I wish people would stop saying 23c or 28c. Tire width is measured in Millimeters. The size is 700C by 23mm.”

I pointed out the the internal inconsistency of Hashbrowns’ request, that tire widths must be denoted with the accompanying mm designation under penalty of death, but somehow it’s okay to put the C behind the 700 when in fact the 700 is in mm too.

And then it went downhill from there.

Come schwable , screw 23’s. it’s all about 25-28 for most of us.
Yes you can! We are waiting!
