I am wondering if tolerance stack up bit you on this installation. Maybe the rim was slightly undersized and the tire was slightly over-sized. Both meeting the manufacturing tolerances.

Both of the 23's that I mounted had to be coaxed on with a small plastic lever, I could not get them on by hand. I normally mount all of my tires by hand. The Schwalbe One tubeless was the exception. I almost got the tire on by hand but it took more effort than I could generate.

On a tandem that would be just before very bad things happened.

Reviewing the One clincher tire specs vs the Ultremo ZX, I noted the One's are some 10gm heavier. I have a bunch of ZX 25mm on hand weighing in at 212gm (215gm is spec). Interesting point is that my 23mm Conti 4000s tires (used on single bike) weighed in at 210gm, so there is virtually no weight penalty using the 25mm ZX tires over the Conti 4000s 23mm tires.

Since I have some new single bike race wheels on order with 22mm wide rims, the 25mm ZX I had designated for the tandem should be a great matchup on my ubber light single too.

Tubeless tires still seem a bit dicey for either tandem or single bike racing. Had my fill of using tubular tires a long time ago. Just MO.

Guess I'll amend that to "barely UCI legal" and "safe".

Don't know anything about this "Black Inc.". Is it a race ready & proven frame or a POC? Do you ride one?

It's Cannondales SuperSix Evo Black Inc built using state of the art nano carbon Technology, yes it's in the quiver of bikes I have, by far the best ride I've experienced on any bike & climbs like a goat!

msrp $ 13310 . Yeah, maybe using that parts list it would knock off 1.5lbs or so from my single too. Cannondale has always been known for stiff frames, but I'll stick with the SL4 which is incredibly good allround and race legal.

Here is an update from Martin of Tiremaniacs about the availability of the 700 X 25mm Schwalbe tubeless tires.

"Still no. Looks like absolutely nobody has it. The US Schwalbe rep mentioned that they have not come on the market yet. BTW, I raced on 23mm tubeless on Saturday (Roubaix style race in eastern WA) – fantastic. On my new Delta profile Rolf Prima ARES4 the width is exactly 25mm. 100 psi rear and 95 psi front. Perfect feel, feedback, and super solid setup. I am out of them as all my teammates decided to get them :-)

Cheers

Martin"

Mention to Martin that at the Ronde van Palouse race (eastern WA) we were there working as corner marshal/flaggers up at Kentuck & Valley Chapel Rd. Linda was the one ringing the cowbell all day long. Gave me a headache worse than doing a tandem ride

Just removed my Schwable One 700x28 to put a new tube in due to a leaking Presta valve, just out of curiosity I weighted the tire came out to be 268 grams a little heavier then there advertised weight of 245.
train heavy race lite!

On July 8th I replaced the Schwalbe One tube type 700 X 25 rear tire with another one exactly like it. The old one was installed on Jan 2nd, it had right at 2,100 miles on it. The tread was getting thin and you could see the cords in a couple of places. The old tire weighed 206 grams and the new one weighed 225. The old one measured 26.67mm and the new one measures 26.01mm.

The front 23 X 700 Tubless ONE has the same number of miles on it and looks like it will go another 2,000+. It has been completely trouble free. No flats no leaks etc.

YMMV

Your rims are 19mm?
Follow up to my earlier post in this thread (above).

I installed some lightly used 28mm Conti 4-Seasons on the same BHS/Kinlin 23mm rims in preparation for an upcoming trip to Italy. Surprisingly, these measure only ~27.8mm wide (only 1mm wider than the 25mm tires we had previously mounted). The 28s are a couple mm taller than the 25mm, which poses a clearance problem with the 3T Rigida fork crown, but there still plenty of clearance with our original ENVE tapered fork so using the ENVE when combined with the 28mm tires.

Compared to the 25mm tires, it appears the 28mm version has more of a height difference than an actual width diff. The 28mm obviously holds more air volume and we are currently running only ~100-102psi (255lb team + maybe 15lbs gear/bottles/etc).

Given that I anticipate riding some cobbles and other marginal surfaces, better to err on the larger tire side than to increase the risk factor with less volume and even 1mm less width.
