Anyone has experience with the newer All black Steher tubulars. I have read in some online shops that they are made with the Black Chili rubber. Are they as good as the old stuff?
I just mounted a pair. I don't know if I just did a crappy job of stretching them, or what, but I had a *much* harder time getting them on the rim and centering them than I remember.
As far as the ride qualities... I don't know. I'll only be using them on a concrete track. Can't tell much from that.
One of the best techniques that I've learned on VS is from Dorman, regarding pre-stretching Continental tires. Soak them in a bathtub overnight, and then stretch them on rims while still damp, pumped up, leaving them on the rim for a few days, before gluing.
I've done this with Conti Comps and it makes a big difference in getting the tubs onto the rims for the actual gluing. Sure, it will never be as easy as mounting Vittoria Pave's or FMB's Roubaix's, but at least you'll be able to get them on the the wheel without excessive cursing or mess.
the tread band looks the same and the website implies they only changed the color.

I think more has changed than the color. The didn't used to be the coating of rubber on the sidewalls--it used to be treated (coated?) cotton, hence the "natural" color. There is definitely rubber now, but it is, of course, thin. Again, I have no clue how this would affect anything. They are still the bees knees for everyday track riding/racing.
I haven't mounted them yet. I actually only bought one to use as a spare and, y'know, examine. They were available via amazon prime and I couldn't resist the novelty of buying a niche cycling item with free two day shipping.
I soaked it for a few minutes then stuck it on a rim while wet. It is pumped up and stretching now. I'll leave it there and pump it up to 120+ routinely until I know it won't be a PITA on the road.
ergott: the veloflex go on by themselves, basically. I really thought that I bought the wrong size tire here! I haven't mounted many tubs yet so my technique isn't very good, but I do what you describe, just not very effectively.
I don't know if it makes a difference, but I soak the Conti's in a bath tub for about four hours, rather than a few minutes. I weigh the ends down so that the base tape is under water.
This year - did the pre-soak, stretched on rims for a few weeks and, presto, I was able to glue them without drama or mess, by myself. Still not as easy as an FMB, but I wasn't cursing!
