FYI...here is the latest road-review of Schwalbe Pro One 23mm. http://www.bikeradar.com/us/road/gear/c ... ess-49856/

"The Pro One is available in 23, 25 and 28mm widths. I tested the 23mm, which I weighed at 240g (the same as Hutchinson's 23mm Atom tubeless tire) but measured it at a plump 26mm when mounted on Bontrager's Aeolus 5 TLR D3 carbon clinchers. This is roughly 20g heavier than an excellent clincher like a Continental Grand Prix 4000S or a Vittoria Corsa CX Open. When you do the rest of the math — adding in 60g for sealant or 80g for an inner tube — the weight becomes a wash. This is a big step forward for road tubeless."

The reviewer used 60g of sealant, not the 20-30g suggested by Schwalbe. Also, the tested weight of 240g is pretty close to the spec of 235g.

for reference the Bonty rim is 27mm outer, 19.5mm inner width

Wow, the 28 is going to be massive on a 17mm+ iw rim. Daddy like.

Yup, should be very interesting on my Reynolds or Venn rims in that both have 19mm ID.

Ive a pair of 28mm sitting in a box. I'll be attempting to fit them on a pair of a23 rims at the weekend. I'll report back if my fingertips are still capable of typing...

If you use the 20 g asf recommended sealant in the Pro One against my 67 g, 48 mm stem tubes with Conti 4000SIIs, the advantage clearly shifts to the Schwalbes tubeless. Very interesting.

How important is ISO/ETRTO as it relates to tire/rim fit? For example, Schwalbe has a chart showing 25mm tires should only be fitted to 13c-17c (i.e. internal bead-to-bead rim width) rims. In the case of the bikeradar review, the author fitted 23mm tires to 19mm internal-width wheels. Are there higher risks of tire-bead coming loose or burping? As an mtb guy, I know burping is an issue.

I've put in about a 600 odd miles into a pair of the new 25mm Schawlbe Pro One Tubeless, ridden on as low as 60psi and as high as 120 (on SL23 rims), in wet and dry conditions (20ml/grams of conti revo sealant).
Whether any actual differences are all in my mind or not, I just love with these tyres, they just seem to surge and roller better somehow.

I wil say the compound does seem on the softer side of tyres, so if you're putting in big miles all the time they not be suitable, but for me, all being well, I plan to run them through the winter and buy fresh for sping.

I'm also looking forward to seeing what other lightweight tubeless tyres come to market.

Any other users out there have any thoughts?

I have the Pro One 23 with about 500 miles on them. 240 grams and about 30 grams of Orange Seal in them and they feel so light and fast and smooth. They measure 25.5mm on AC Argent wheels. FYI the latest issue of Velo News has a rolling resistance test of a bunch of Tubeless, Tubular and conventional clincher tires and Tubeless came out on top.

That last statement is kind of misleading... A Tubeless tire came out on top, not tubeless in general came out on top. Yes the Speci S-Works Turbo tubeless in a 26mm ranked first, but the same tire in 24mm placed 5th, behind some other Speci tires and directly behind the Conti GP4000s in a 25. The Pro One was not even tested, and a bunch of tubeless tires finished midway down the list, or worse.

Basically, there are a lot factors to consider, with rubber compound and contact patch being the main ones. Variations in inner rim width are likely to have an effect on watts needed to maintain a certain speed (as per the test in Velonews). i.e. you could take the top contender (S-Works Turbo Road Tubeless 26mm) and put it on a different rim and it could finish lower, where as you could put the 24mm version on that different rim and it could come out on top...

I was surprised by the fact that the top place tire and 15th place tire were separated by around 10 watts at 40kph...

Oh, and there were no Tubulars in that test.

Aren't there tubulars in the test? Is this different?

Open tubulars are not the same as tubulars. Open tubulars are basically clincher versions of a tubular tire... Confusing I know. I just call them all clinchers, but some people feel there needs to be a distinction between the two.
