I've been using ultremos for about 3 years. Had a pretty good run until the newest set. The rear tyre sidewall punctured after about 1000km.
From now on will probably go ultremo front, gp4000 rear.

Puncture resistance = 4000 (gators are even better)
Grip = Ultremo
If you want something a bit more durable then look at the Durano Plus. You won't get the milage that you do with the 4000 but they are tough and have very good grip.

With tubulars I started on GP4000S (22mm) but wrecked 2 rear tyres quickly (sidewall cuts). I switched to Ultremo HT and haven't had a problem. Heaps of grip and fast - not as durable as the Contis but they have cut up or let me down.
When my backup of Conti clinchers runs out I think I'll try the Schwalbe 25mm clinchers but both are great tyres.

It's going well, no punctures and feels pretty similar to ride. It's a bit heavier but doesn't feel that much different.

However my c24 ultremo DD was down to the canvas so I had to do something. I took the Dd off, removed the blue factory rim tape, and replaced it with cloth.
I then grabbed one of the near new ultremo ZX that had blown off the c50. I fitted it using the usual procedure and pumped it to 140. . If its still up tomorrow afternoon ill drop 20 out of it and ride it. Cross fingers.

I did have one on the front as well but lent my wheel to someone with poorly set up brakes and it destroyed the side wall .

The latter is 10g heavier but apparently much more durable.
That's not a calculus in favor of DDs IMHO.
Though suppose it boils down to what value you afford an AUD.

Apart from the blowing off issue which we might have gotten to the cause of now... I really like the DD's. I've worn two down to canvas and am yet to have a flat. They are very resistant to cuts and general abuse. They are good tyres. I really like the combo of a ZX on the front and a DD on the back.winstonw wrote:Just realized the cheapest Schwalbe Ultremo DD on the net is around AUD45 vs Conti GP4000s at 25% cheaper.

I don't doubt the GP4000s is a good tyre too.. so if you can get them cheap...... Personally I think a GP4000 on the front would be a bit of overkill myself. I like the idea of a lighter tyre on the front. They don't cop the abuse that the backs get and don't seem to get nearly as many flats. Maybe a conti attack on the front with a GP4000 would be a good mix.

ultremos, but while waiting for the pro3's to wear out reading
about Comedians experience had me a bit concerned.
So installing them I checked and rechecked the tube was sitting
in the tyre correctly even blowing some air into the tube to
give it some shape before installing.
I have only 250km on them but they seem ok, roll a bit faster
than pro3 (allready a fast tyre) fit on C24's a lot easier than
pro3 (nightmare to install) but at same 115psi ride a lot harsher
and run at 100psi to get similar ride quality(still not as nice) to
pro3, I can only imagine what the tyres max of 145psi would ride
like.

Currently in email conflab with Dave the man at Schwalbe - very helpfu - have sent him photos but beforte he received them he sent me this, which is interesting so I thought I'd share (I didnt realise that the ultremo ZX HD were essentially race tyres with minimal armour - d'oh - I thought they were actually meant to be heavily armoured)
"The HD SpeedGuard is our very lightweight puncture guard protection
for competition tyres. Although effective against small shards and
thorns, anything larger will of course penetrate the puncture guard
layer. Something like the Durano Plus will have faired better but the
weight compromise is substantial.
If what you can see are loose threads that you can pull away from the
sidewall then this is part of the chafer. It's made up of woven cotton
material, which prevents the carcass chafing on the rim. Some of these
cotton yarns are not clamped in between the rim and tyre bead and
become loose, because of insufficient rubber coating. You can simply
cut the yarn and go on riding
It is not dangerous because the chafer is a separate part of the tyre
and doesn´t belong to the carcass. Some tyres don´t even need a
chafer. Even if you completely remove the chafer (and this is only
possible if the tyre is off the rim), the bead is still completely
hidden by the carcass."

anything <=200g is marketed for comparative light weight, as is advantageous in racing.
anything over 220g is marketed and designed for durability.
200-220g attempts to be a jack of all trades.

Based on this nobody's opinion should be shared. ...way too may variables. As this probably applies to 75% of all discussions on this forum, perhaps we should go ahead and close it down?winstonw wrote:Those who claim one tire is "better", are making a very dubious claim if they don't include bodyweight, tire width, and surfaces regularly ridden, including whether they ride in the wet.

The Pro Race rolls smoother than both, but are too hard to get on and off.
You will need to buy Ultremo at roughly twice the rate of the GPs, as the Ultremo wears much faster.
