This is about clinchers.....
I'm the only guy I know who doesn't mind using different tyres for the front and rear. I'm about 86kg, so I go through rear tyres a lot quicker than my lighter mates, therefore, I usually use something more durable and flat resistant on the back, and something 'nicer' on the front. Also, i like to ride to the local races in the crit season, so using something uber-fancy on the rear, like an EVO CX, may risk flatting on the glassy roads around the race course (most of the courses are in industrial areas).
I've been using Gators on the rear for a long time, mostly ffor training and on my wet day bikes, but since I noticed that GP4000Ses are reasonably priced on the net, I've been using those on the back lately, and they've been going ok. I'm gunna ditch the Gators and try the GP4000s as rears for a while.
The Gators obviously don't feel as fast as the fancy tyres, but if I pump the rear up to about 130 (or more on good roads), I don't notice as much. I reckon I feel crapper tyres more if they're under my hands; generally, and when steering.
GP4000Ss feel ok to me (I've had them on both front and rear), but not as good as Vitoria EVOs or Pro Race 2s. Some people rave about them, but i don't know what the fuss is about. They tested as fast as PR 2s and 3s in the test below, which surprised me a bit. I've been a bit of an 'anti-Conti' guy since I realized how horrible GP3000s and the old 'regular' GPs were, but the GP4000Ses might turn me around.
I reckon Pro Race 2s were the best balance of speed and grip, with reasonable durability and puncture resistance for a racey tyre. The price on line was ok, too. I'm disappointed that they've become hard to get. Are they still being made? I liked them a lot.
Pro Race 3s feel a little sluggish and spongey to me, but very, very grippy. I like having on on the front for fast corners. I hated them at first, then I reckon i figured out that they go a bit better with 10 to 15 more psi, compared with other tyres. I was very suprised that they tested the same as PR2s on the test below. I haven't had the poor durability and 'cutting' problems that other people ont he net have had. The price on line os ok, so I'll probably keep using them.
Vittoria EVO Open Corsa are great. These are the only tyres that blew me away, and finally made me realize that there was a big difference between good and ordinary stuff. They feel very fast and grippy, but are not very durable at all, and seem to cut and blow at the drop of a hat.
A few years ago, I had two of them slice and blow, just from riding over sharp stones! These tyres are very thin (there's not much rubber on them, and the casing also seems very thin), so I guess it's little wonder that they feel great, but don't last. I currently have a few EVO CXs, and I sometimes put one on the front for a race. They've a bit expensive, even on line (over $55AUD on some Brit sits), so I might baulk at getting any more for a while.
I've never had a Diamente, but i intend to try them one day.
I used Vredestein TriComps for a long time, because I was getting good deals from my local shop, but I had a bad run with them going out of shape way before they wore out, so I stopped using them. This is when I switched to PR2s, which immediately felt faster to me, so i never went back to Vredesteins. Their lower and mid-range tyres are simply horrible. Even their slicks don't feel fast to me. I think they revamped their models last year, so I might try them again soon.
Schwalbe Ultremos are ok, but nothing special. To me, they feel like a slightly slower version of PR2s -- very similar. I reckon they have a loose fit, so they go better on tighter rims. I'd use them if the price was great. As with Vredesteins, their mid-range stuff is worse than a garden hose.
Specialized tyres are disgusting, but i haven't ridden on any for a few years
That's all I can think of at the minute. I've never had any fancy Clements, Dedas, Zipps or Veloflex clnichers.
I cut out the tubulars on this test
