If you need an ultra-light Conti, the Supersonic is widely available. If you ask me, even a 175g 4000 is still going to be outperformed by the 195g Michelin Pro3.

And the SS has the same casing as the 4000, only without the puncture layer, and the tread is thinner. I've had no issues with the SS in a few hundred miles of riding.

IMO this is a no brainer and I'm surprised that more companies don't do this. Just make the tread half as thick and sell twice as many tires...
The Ultremo Rs are already that...1/10th the life of any racing tyre buwahahahaha
Slightly worse in the wet(but the S is excellent in the wet mind you)
Good for TT's

Bumping an old thread, for a small correction. Not getting into another Tour testing debate, just some facts:
- When talking rolling resistance and weight, Continental did not win, Veloflex did; the Record clincher is hailed as the lightest and best rolling tire ever tested. 2nd place in rolling resistance is the Continental GP Supersonic. The 4000 RS is in third. It did win the overall test (better puncture resistance and grip in the wet).
- The best rolling tubular tested was the Vittoria Crono EVO CS 22.
- Tour does test at the Continental facility, so it is logical that the Conti tires are optimized for that. Tour does however use there own measuring equipment.
- Tour acknowledges the effect of the inner tube. They tested with a 75g butyl tube (as opposed to a heavier tube in previous tests; results not directly backwards comparable) and state that with a latex tube, the rolling resistance of the clinchers, as tested, would drop by 2-3Watts.
- There is no measured difference in puncture resistance between the RS and the R (previous tests), as both tires pass the 180 second cut-off point in Tours' test (sharpened screwdriver pressed on the inflated tire with 35kg force, mechanical rocking motion applied)
- According Tour and Continental, the RS has a new compound, so it's not a R with a thinner tread, but it does have only half the tread depth. Tour tested the life of the RS at ~3000km for the rear tire.
I love you guys. Seriously.

For example, Tour no longer tests at Continental. They have their own setup, purpose designed and built. It can measure rolling resistance in corners, not just when the wheel is perpendicular to the road. Nifty.
