I'd like a tire that has super low rolling resistance when riding upright, but has decent traction for cornering. It'd be for a race I do each year that has multiple 2 hour long climbs per day with a couple fast descents between them. Most of the time you're climbing so low rolling resistance would be paramount. Not sure I'd win with those tires but a few free watts wouldn't hurt.
Imagine a handmade tubular tyre crafted to the best know how of its kind, no puncture belt whatsoever.
That tyre would probably weigh around 220g or thereabouts.
Now all you'd want is a very supple casing, not too wide, say 23mm and a latex inner tube of the best pedigree. 55g and not too lossy.
Add a top notch cotton/silk ? casing with a true high TPI count around 300, a compound a la Veloflex or Black Chili and what do you get?
By tyre, I had tubular in mind but that's really irrelevant. The idea is to really think up horses for courses and see what turns up eventually.
With some luck, you're idea will be picked up (mine tend to so why not yours) and you'll end up with the tyre of your dreams.
Don't get the wrong idea, I just want to find out what the ideal tyre should look like for whatever circumstance you use it for ( this would create an infinite amount of variations on a theme, yet this not J.S. Bach)
As an example I currently use pre-aged (from 6 months to several years) Veloflex Carbon for what I view as a leisurely ride nearing 30km/h on roads that do not present a puncture risk. At least not for these tyres anyway.
So, lets take it one step further, and another. Just to see where the minimum of belts and braces can lead us.
