Vittoria Corsa Evo CX 20mm or Veloflex Corsa 20mm

Well, the title pretty much says it all....

I ride Vittoria, but a 23mm. Love them. I don't think you would be disappointed in the VeloFlex though. I would go 23mm though. Nicer ride, just as fast.

Vittoria but use the 22mm ones...

Wider are faster - lower rolling resistance.

Assuming we're talking about clinchers here simply because you forgot to put "Open" in front of Corsa CX.

Go Vittoria and nothing less than 23c, they come in 20,23, and 25, no 22, not even in tubular. The Veloflex Corsa does come in a 20 and 22, but 20c clinchers ride like jackhammers, they're quickly becoming a tire size of the past.

Keep in mind that Vittoria rubber is less durable than most, very sticky in the corners but wear extremely fast. Unless you'd be using the Vittorias specifically for race day, go with Conti or Michelin instead for an everyday tire.

20 mm, 20c are for cars

I use 20 mm on the front wheel for pretty much all riding types, it rocks. Here's one recent case in point. I was on a group ride on my last set of Vittoria Corsa CX 20mm (I've switched to Conti's) which were aged ~2k miles and as I get near the front on for my pull, BAMM! I hit something and it ripped the tire open and (from someone behind) the front wheel actually popped up a bit, mini wheelie. Due to it being a 20 mm and fitting a bit tighter than a 23 mm tire, it stayed on the rim and I was able to safely pull over after someone blocked the pack that was behind me. Booted it and rode home fine. Had it been a 23 mm most likely it would of blew off the rim as rear tires have done before.

I keep hearing that 20 mm are not used anymore but I keep finding them in new tires being sold so some people are still buying them no matter what you hear otherwise companies would stop making them.

Not to derail but Conti's 4000 are much better and I've had no issues with tears in the tires unlike my old favorite Vittoria, hence why the one that blew was the last in my stock pile of tires. Yes, I'm one in a X but that's my experience with them.

Yup, I meant clinchers. Whoops! I get the problem of the tyres being too wide and rubbing on my chainstays (yesterday, I was riding out to racing and my 25c Continental Attack wore down and punctured) so I need a thinner tyre to stop this happening.

I've ridden Vittoria Corsa CXs 23c (clinchers) and I have been pretty happy with them, but going back to my problem, I need narrower tyres. Tubs are too expensive for me, and I don't have tubular wheels, but clinchers do the trick!

Gotta ask, what frame are you riding that a 25 won't fit? Just about every road frame out there can fit up to a 28, every single road frame I own from steel to carbon has 25c tires on them and I never had the problem you have, heck, I ride 28c on my Colnago for training all year. Look at what's being raced in Paris-Roubaix... 27c almost across the board.

Odd.

I ride a 2011 Felt FC (stock frame for an F5, F4 and F3). I had a 2010 Felt F1 Sprint that wasn't manufactured properly. Every time I pedalled hard, like in races and doing efforts, the wheel pulled to the right and gouged out a bit of the chain stay and deemed the tyre useless by wearing out the side wall. I use Shimano WH-RS20s to train and sometimes race.

Maybe it was just the frame. This frame is a lot better and a lot stiffer.

Yeah, I was going to guess either a frame or wheel problem. Personally I don't ride anything smaller than 25c. I used to ride 20c tires in clincher and tubular and find them to have atrocious ride characteristics in all aspects, cornering and straight lines, everything. When this topic of tire width came up a few months ago I said the same thing about 20c tires and ElChingon was one of maybe 2 or 3 posters that said they still use a 20c tire, that story that he just wrote about if he would've been on a 23 instead of 20 and the tighter fit in a blow out is a bit off, I've blown 23 and 25 clincher fronts at extreme speed and never encountered what he's talking about, but I race nothing but tubulars for the safety aspect at any width. 20c truly ride like crap. Stuff the widest tire that your frame will allow.

I use to train with Attacks are a 22mm front tyre, the force is rear and 24mm IIRC
Get 23 GP4000's or Gatorskins/GP4Seasons for training - they crap all over CX (although my CX experience is tubulars) THey wear fast, they also cut, they DO have great grip, but not enough to make up for the DNF's!
Can't say with Veloflex

Also,in my opinion, o not go too wide if you have narrow rims, if the bead is 18 /19 mm then 23 is fine, bigger balloons too much

Not answering for the OP, but I would have difficulty fitting a 25mm in my Dedacciai Scuro HCR frame (mine is from Ribble, but Dolan, Bottechia, Kona and a clutch of others also sold the same frame), and it certainly wouldn't fit a 28mm. With a 23 mm GP4000 I have less than 2mm clearance on either side.
I don't know if they fixed this in the Scuro RS.

When I used my Continental Attack/Force duo, I found the riding to be really tough, due to the difference in tyre sizes from front to back. Riding a Tufo Clincher-Tubular (21mm) was really easy to handle with an Attack on the front. On track and road (400m concrete track) it was really simple to handle. I guess it's all about personal preference.

Are you sure the wheels aren't the problem?
