New Veloflex Records beat Vittoria Corsa Speeds
Quote | Reply
But are outrageously thin at 144g! In our roller testing ~5w faster than Corsa Speeds at 45kph for a pair of wheels, when coupled with Vittoria latex inners. We also did indoor velodrome testing last week which corroborated these results, using one of our AEOX Titans (100mm deep) as a test wheel.

impressive!


I always loved Veloflex tubulars. Will pick some of these up.

Also not tubeless compatible - maybe they are so thin that sealant wouldn't have a good shot of sealing small punctures anyways, but that does slightly alter the risk/reward calculation in running a tire that one would think (based on weight and thickness alone) would be very fragile.

At that weight, the Vittoria Pista Speed, not the Corsa Speed, is probably the fair comparison.

I could hardly get out of my driveway on the Corsa Speeds without getting a flat! Those Veloflexes might not make it out of my garage!

Vittoria doesn't have a pista speed clincher, unfortunately.

But kinda of makes sense as you wouldn't want to run a clincher at wood track pressure.

The use-case for ~145g tires clinchers is pretty narrow. Asphalt/concrete tracks and really pristine TT courses. I still mostly run tubular on non-wood tracks just for the safety aspect.

I'm pretty daring, but Corsa Speed is about my personal limit for amateur TT courses.

Are you referring to the original (G1.0) or current (G2.0) versions? If the former, I had similar experiences. But I've found the current G2.0 version to be much more durable. I'm not saying it's a Gatorskin, but a marked improvement over the G1.0.

I'm going to give them a go and see how they workout for me. I do have pretty pristine roads and I had zero flats on my Corsa Speeds. But it might be an expensive experiment that doesn't workout for me.

True, as it would blow off the rim, which would be very very bad. But this on is starting to touch the Corsa Speed Pista (SWAG). At a 125-30 psi it might be just as fast or faster due to lack of hysteresis.

Since you did some on track testing, how was the CdA+Crr? 5 watts of Crr is a whole lot to overcome with CdA from another choice.

Let us know how it goes because 5W is Real Watts (tm).

yeah, will do! it was crazy when I saw that.....I was on the road when I saw the results, but as soon as I got back in front of my Mac I order a pair up. Again, pricey at €99 shipped, but I'd pay that all day for 5W if I can get some miles out of them. That being said, if they do well for me I might not be the best test case as "delicate" tires fair pretty well under me. Conversely, if they don't make it out of the driveway it's bound to be a tire that no one should ride. ;)

At 144g it would be difficult for the tire to have adequately-low sidewall porosity to contain sealant in the first place, or be stiff enough about the beads for tubeless seating to be both safe and practical.

It's definitely not clear cut, Corsa Speeds might be the better option but we've got a race this weekend (national closed circuit/motor circuit TT champs) and 3 of our team will be on Records for that, so we'll get an idea of how they perform on a nice surface at least.

I should probably do the Pista clincher (they don't do a Pista Speed clincher but the normal Pista has graphene etc.), they're what I use for training on the track and it's a similar construction!

Uh. where are you seeing 99 eur shipped, unless you're talking for the pair.

Yes definitely - on our Titan, the CdA for 23mm Record is almost identical to the 23mm Corsa Speed.

Maybe it's just me, but I'm not sure a pair remains available from Veloflex. The website will allow me to place one in the shopping cart, but when I try to update to two tires, I get the message "The requested qty is not available"

1.0. Fastest flat I've ever had on a new tire (I think a quarter of a mile?) and particularly discouraging given how smooth and clean the roads are in my community. At IMFL I was a SAG driver and helped a number of people fix flats. First... I'm amazed at how few people know how to change a tube/tire. Second, about 50% of the flats I tended to were Corsa Speeds.

huh. My order is showing a qty of two. I figured there might be a run after Xav posted the results so I pulled the trigger quickly. I would have held off but I have worn completely through the rubber on my Corsa Speed 1.0s and I need to replace them

Everything I have read has said the same thing and friends personal experience mirrored that, but damn if I didn't get a lot of miles out of mine. Like I said, I might be an outlier in terms of tire durability or really, really lucky. I should go play the lotto...

On a side note the open tubular records seem to be sold out now. They were showing in stock when I ordered just a few hours ago.

I'm n=2. I've used Corsa Speed for TT, RR, criterium, and non-wood track for years now, and they've been just fine.

I can only remember one flat off-hand. That was a pinch flat in a 100-mile TT. (tubeless pinch flat, no less, which was a feat).

I've since gone to GP5000TL for RR and criterium for grip purposes (Corsa Speed grip in the wet leaves a lot to be desired), but sticking the CS for now for TT/track. I've worn 3-4 sets down to the casing.

I’ve had a set of the new Records for a couple of weeks, and have put about 35 miles on them on the roads of southern New Jersey. So far so good in terms of reliability; not flats and no cuts, gouges, etc in the rubber.

They are THIIIIIIIIN though!
