Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Analysis paralysis: GP4000 or Corsa EVO CX?

It's getting to be time for new clincher tires. I'm currently riding Continental's Force / Attack combo, which has worked OK. I replaced the front awhile back when I didn't try hard enough to avoid a fair size rock and got a bubble / tear on the sidewall. Rear is looking ratty and thin on the tread. No flats (knock on wood!) in 1.5K mi. The roads around me are in average condition. Not bad, but certainly not autobahn smooth. No foul weather riding for me.

I've narrowed my search down to two tires: Continental GP4000 or Vittoria Corsa EVO CX. I'm paralyzed by analysis at this point and figured a poll would shed some light on the matter. What I do know is that I'm going to choose a "20" up front and "23" out back.

If you needed tires tomorrow, which would you put on your road bike?

Given your budget and apparent need for top-O-line race rubber, I'll suggest Veloflex Pave. You won't go wrong with any of the three, though.

Why would you put a 20 up front for training purposes?

Michelin Pro 2 Race Service Course - "Special Edition".
These are more supple than my previous GP4000( which were quite harsh at 115psi), weigh slightly less, have less rolling resistance and more grip, only outstanding issue is I haven't tested their durability. In 900km I have had no flats or cuts.

Point to remember these are not your everyday Michelin Pro 2 Races, they are part of a limited production run.

As a reference I'm using vittoria latex tubes (65g) at 110psi.

I get them from here.

Easy. Just pick the cheapest.

The EVO CX's are extremely supple, but cut very easily. I ran on Pro Race2s last season and barely had any cuts on the tires. This year, with the CX's, I've got numerous nicks and cuts everywhere. My routes haven't changed, and I haven't done any foul weather or crappy road rides on the CX's.

The Vittorias are daaaaamn smooth rolling compared to the Michelins, but the Michelins seemed more cut-resistant. I think my next set will be Vredstein Fortezza Tricomps, and hopefully I'll reach a happy medium.

I have both... but haven't ridden the Corsa yet. The Gp4000 are amazing. I have no cuts what-so-ever after 1,000+ miles. I use these tires for training and am only going to use the Corsas' for racing.

Shop at PBK and then you can buy both!

I'm using GP4000 now on my bike, and haven't had any problems yet after about 1000 miles. They seem to be good as new.

I'm going "20" upfront because that's what I've got now and I like it. Not twitchy.

Cheapest option is GP4000. The Mich Service Course are the most expensive by a long ways. Vittoria is in between.

I'm thinking I can't go wrong with Continental!

Thanks

I'm using the same setup your proposing with the Vitorria open corsas. I find all Vittoria tires cut fairly easy at high psi, even the Rubino pros I've used in the past have lasted over 5000 km of flat free riding and only wore out from trainer use. My open corsas with about 1000km on them are flat free but do have some cuts from when I ran them at higher psi. At 110 psi both front and rear they are nicest tires I've ever riden on.

I have the 4000's in a 20/23 and have zero complaints. I got use to the 19/20 up front from my tt bike and just like the feel. (that and its 10g lighter which is an extra 1/8th of an ounch of water I can carry and still be a WW )

i used both vittoria open corsa cx's and gp 4000's this season. i got so many flats and ruined tires from cuts with the vittoria's that i'll never use another one. i went from two flats a week to zero when i switched to gp 4000's and i think the gp 4000's feel stickier (@ 120 psi). i ran the vittorias at 110 psi and 130 psi and noticed no difference in flat rate or tire ruination. after 1,000 miles i don't see many nicks on the gp 4000's and i've had zero flats while riding the same roads. pretty impressive.

what's autobahn smooth, and on which autobahn do you find it?

Well, I am using GP 400 tires. I've only put 60 miles on mine though, so there is that.
But I like them, my bike feels great (not sure if it is all because of the tires though). THe 40 year old cycling veteran at my LBS (and owner) swears these are among the best tires ever made though.

Johnny Rad, are you going to use these tires for racing? If not then got Conti GP 4000.... if racing buy the corsas for race day and get a more durable tire for training (the contis.)

i've ridden extensively on both. the continentals are bomb-proof but just aren't that smooth. i would recommend them if you have bad roads. i prefer the vittorias. a world smoother tire. i've been on 'em all season and they still look good; not worn flat or any cuts or other problems. and i haven't had the problems with flats that others have. the roads are nothing to be proud of around here, but i haven't had a flat with these tires yet. i'm 155 pounds. if you're looking for a compromise between the two, i would recommend the michelin pro race 2. my research indicates they are about as smooth-rolling a tire as the vittoria, and generate only slightly more rolling resistance, but are a lot more cut- and flat-resistant. i'm gonna try them when my vittorias wear out

I don't think you have a 20 up front if you're riding Attack/Force. The Attack is 22 and the Force 23, to my knowledge they don't come in other sizes.

I usually use Attack/Force, but have also used GP 4000's. Personally I can't tell any difference. The GP 4000 might wear a little better.

The Michelin Pro2Race "Special Edition" tires are a marketing ploy, mostly: much more expensive than the regular Pro2Race but not much different. You can get the regular version for about 1/2 the price, or any of the other tires you are considering, from Probikekit.com. Any of those tires will serve you well, with the differences being matters of preference and individual use, as suggested by the fact that each tire has its supporters.

I've used the Continental Attack/Force combo, Continental 4000s and Vittoria Open Corsa KS on my Tarmac. You'd have to pay me to ever put another pair of 4000s on my bike. No they are not bomb proof, I went through a rear tire in under 300mi. as the "super tough" vectran belt shredded like wet paper. I've been several thousand miles on Vittorias (two sets) with hardly a nick. The Vittorias are smooth as silk, and handle great. The 4000s, well, like I said, you'd have to pay me to put another set on my bike. The 4000s skipped off of each imperfection in the road. Coming around corners I always felt I was one bump away from loosing the front. Plus they were so harsh they were a beating on bad roads. No such issues with the Vittorias. The Attack Force combo has better grip than the 4000s (but not the Vittorias) but is still pretty harsh in comparision to the Vittorias and the Vittorias handle better. Given a choice, no contest, not even close - Vittoria.

It's funny how a tire can work well from some, and be terrible for others. I tried Continental once, back in the Grand Prix days. It was absolutely the worst tire I have ever ridden. I constantly got flats. Anyway, I would argue that you can go wrong with Continental. On the other hand, I have friends that would not ride anything else.

Corsa rides better - GP4000 is more durable. Corsa front and GP4000 rear - works for me.
