Ever tried a Vittoria or Veloflex in bad weather conditions? If yes, you probably already stopped using them. [emoji6]
The most important feature of a racing tire is (at least in my book) reliability in all conditions (followed by low rolling resistance). No other tire comes close to the 4000S or Competition (if you prefer tubs) in this regard. And yes, I've been on quite many (not to say all) of those mentioned in this thread.
Conti Gp4000s2 is really like no other…. few examples FME :
- flat every 50-60km, finished by blow off ( sidewall ) after less than 500km ( 25mm)
- they're harsh like no other (23mm , shop changed 25 for new set of 23 )
- they "flatten profile" with mileage, what make them rubbish (unsafe) on cornering
Really good tires GP4ks2 saw maybe at store. They are not even close to Vittoria or Veloflex.
And yes, I rode Vittoria ( incl Rubino Pro3 ) and Veloflex on wet, even in hard rain, even 60-70kph downhill. Never felt safer on Conti. Can say felt less safe, much more less.
Where conti got flat ( same routes ) I did NEVER puncture Vittoria , nor Veloflex . ZERO flats, 2 seasons.
Did I mention PITA mounting Conti tires ?
Overall they're not bad, but do not belong to high-end class. Never did, never will. Explaining by price, they're in 20€ ballpark.
