What are you using for rim strips? I mounted the Corsa G+ 700x25 on Zipp 303 FC with the rim strips Zipp supplied and found it somewhat difficult. Last week I mounted Corsa G+ 700x23 tires on narrower 2011 Reynolds Attack with Panaracer rims strips and had to use a Kool Stop Tire Bead Jack to get the last few inches of bead on the rim. The next day when I decided the Panaracer rim strips where knackered, after installing Zeffal adhesive rim strips, mounting the same tire the simply could not have been completed without use of the Tire Bead Jack as I do not have enough skin on my fingers! :lol:

Most open tubulars are difficult to mount first time, but stretch out in the process. By far the most difficult combination I encountered was a Challenge Grifo (not the clincher version but the open tubular) on a tubeless ready MTB rim (since 29er rims are compatible for cyclocross use).

After that first installation, changing between these tires and my Challenge Limus tires for deep mud became quite easy.

You're making a distinction between a "clincher" and an "open tubular"? Why?

There are two non-tubular tires called "Challenge Grifo":
Clincher: http://www.challengetech.it/products/cy ... ifo-022/en
Open tubular: http://www.challengetech.it/products/cy ... ifo-019/en

The Challenge website it actually showing a picture of the tubular version as it looks very similar to the open tubular version which can be seen here: http://content.competitivecyclist.com/i ... 0N/BLA.jpg

While the terms are used interchangeably, often times 'open' denotes that the 'clincher' version as was manufactured in a similar manner using the same materials as the tubular tire.

Yes, it's marketing. Basically the same construction as their tubular, but in a clincher version, hence "open" tubular. Aka clincher.

Not necessarily. Open tubular & clincher are used interchangeably but there is a fundamental difference. Open tubulars are constructed in the same way as the tubular version with a cotton casing and cold applied tread strip. The clincher versions will be different in casing construction as well as the tread being applied using heat.

Exactly. Clincher in the way Challenge uses the term means that the entire casing is soaked in rubber that gets vulcanized to it, so this includes the sidewalls.
I don't have a more exact term for it, I just wanted to point out, that all tires I encountered constructed in the "open tubular" way tend to be a very tight fit during first installation and stretch out significantly during use making further installations a lot easier.

Ok, I see. I think that's kinda what I was saying wasn't it?... "Basically the same construction as their tubular, but in a clincher version."
Actually, now that I reread I think it was my use of the word "marketing" that might have thrown things a bit sideways. I guess I assume they call them "open tubulars" to distinguish them as higher quality construction than their regular clinchers? Would that be fair to say as I'm not an expert in their actual construction. Or are they of the same quality but just use different methods of construction to get there? I don't know.

Open tubulars casings are constructed the same way as a tubular tire.
A cotton or poly cloth strip, with a rubber band glued on the center.
The "open" version has a "rod" sewn to both ends of the cloth piece instead of being completely sewn around an inner tube.

Like written previously, clinchers are built like .... clinchers.

Open Tubulars are built like clinchers were built in the 1st 100 years after they were invented :)
