Schwalbe Ultremo ZX vs GP 4000S

[Zatek]

Looking for my next race tires for road races. The tires will go onto Easton EA90 SL wheels. Did some research and the Ultremo uses 20 w less than th GP4000S tires at the same speed. I have used the GP4000S but don't want to make a mistake.

 

Thanks

Have a look at the Vittoria Corsa Open CX. The clincher version of their famous tubular. Google reviews online. Their Diamante Pro is sub 200g but Im guessing with 220 tpi its not as durable. www.vittoria.com. Nothing wrong with GP4000s, I have yet to have a puncture with mine and they are 205g each.

Used a set of Ultremo's for a while until it rained.They are quite slippery when you ride on the road marking paint.

 

Never had that problem with my GP4000

Can't comment on the Schwalbe but I've been very happy with my GP4000.

Schwalbe Ultremo DDs and ZXs are superb. My feeling is that the conti's are too hard and doesn't offer the same amount of grip as the Schwalbe's. The DDs have excellent puncture resistance. They are heavier than the ZXs, but that's why I use them as a training tyre. I'm not into weight weenie mentalities, so i'd probably 'race' on them as well.

 

I dont have any problems of serious slipping on wet road markings, if only because i try to avoid them as best I can. When unavoidable, it's a non-issue so far.

 

mate of mine has been using his ZXs as his everyday tyre, and it's been wearing pretty well. They have super grip, and in his estimation, better than the contis which he considers overrated. He has been expecting high wear rates from the ZXs, but so far so good. His expectation of higher wear rate is reasonable given that all tyres with high grip experience high wear rates. Logical.
