Will be great but it’s only came up because their tyre now has just been knocked off the top by veloflex as the fastest. 5-7 watts per tyre and at what speed?
Just did 800km on Mallorca, including the 225. Conti 4 Seasons, no punctures or pressure loss. Most of us don't do races, but ride with friends and groups. For me, avoiding a puncture is way more important than 10 watts more or less.
Just to reiterate for those that didn't see the "AD" mark in the thumbnail. This is an advert. Reporter paid by vittoria says "Measurable improvements found", doesn't state them and then goes around interviewing teams paid by Victoria who give subjective feedback on how "amazing" it is. Wait for the review on BicycleRollingResistance, comparing it to a GP5000, and decide which one fits your personal ideals in what you want in a tyre.
Is it foolish to assume that date of manufacturing also plays role? If BRR would test 10 years old stock I suspect same brand same model tire would be harder and slower than fresh one. Maybe too fresh also isn't too great - just guessing. Just like roasted coffee needs to rest for a week or so and goes stale after 4-5 weeks. So if BRR buys three years old GP5K to compare against 3 months fresh VCP results could be suspect.
Yes it is an advert, and very well done it is. The GP5000 and anything with grip, will be a touch cheese like in robustness. Saving is 5W +-15W is my guess but that is fine as well. Wider tyres means bike frames made for wider tyres which is great, gone are the days of frames so stupid they would not take a 25c tyre.
I'm not sponsored. I ride these tires. These tires are better. If you think a team like jumbo would swallow all the marketing and ride bad tires, while they have enough money to choose whatever tires they want... Yes those teams are sponsored, but if it doesn't work, the'll move away onto the next tire. They have enough offers for sponsoring.
I agree, although it is a balance for me... I don't see the point in running race tyres for everyday use, but bombproof options can be rather harsh and drag a lot too. I run vredstein fortezza senso extreme in winter. Never punctured in two years despite occasional off road use and they last ages. But when I fit Hutchinson fusion5 11storm (all weather tyre) the ride feel is much nicer. These are not even fast tyres in the tests and I don't run tubeless either (more drag). Puncture protection is good and better than conti 4 seasons. I recently tried GP5000 with tpu inner tubes for a sportive . Average speed went up noticeably (less work for the distance) and ride feel improved loads. Like riding a different frame. I won't ride them all the time, but it was a worthy purchase. I would not ride anything racier though, as there seems to be little to no puncture protection.
@@knarf_on_a_bike That were regular GP's which you had puncturing? Or GP 4K, 5K? To me Gators look like a tire to use in pub area where road can be seen under glass shards, not on regular roads as it is deadly tire meant to be durable.
GP 5000 & Silca Ultimate Tire Sealant. I set it up for a buddy who rode 5500km in Thailand with no flats, the Silca tubeless sealant is INSANE. I actually had a puncture last weekend when I rode muc-off sealant, it literally did nothing. I took the tire off after i got a new batch of Silca Sealant. After taking it off, I did nothing to the tire, added the Silca sealant and put it back on.. tire holds air like a champ again.
Great video, love how enthused you are geeking out on tyres. I’m fascinated especially because it’s the best bang for your buck performance upgrade there is. I’m old and slow and don’t care much about speed, but every watt saved is a bigger percentage of my total power, so it just lets me cycle further and see more for the same effort.
Great to hear you've found a tyre that works for you! The pros are looking for any small advantage they can get and the teams using these tyres have been flying 💨
They look and sound incredible. Having used G2.0 a handful of times over the summer months I think (being the amateur I am) that I notice a difference. Also strong physics chat again Dr B. It’s cool looking cool with those tyres but super cool to understand what makes them work, and how to get the best out of them!
Im surprised that Jumbo Visma still runs these tires after 2 years of failures in the roubaix. How come GCN hasnt followed up with the results and causes of the failures? Why would i ride them when the pros have so many flats?
@@gcn The Paris Roubaix where WVA was on the wheel of MVDP with 15km to go and flatted, denying him any chance of victory? You're seriously using that race to illustrate the reliability of the new "secret weapon"?? lol
Just my 2cents it might help somebody. - I used to run on Specialized S-Works Turbo RapidAir 2Bliss Ready with Stan's sealant and Bontrager sealant. Was a mixed experience. The tires ride comfortably and felt speedy but probably that's all I can say positive. Got plenty of flats that got sealed though, so no standing on the side of the road, but the sealed holes could not hold the pressure afterwards and they re-punctured if I pumped them to a proper pressure. Also these tires turned like a tractor, cornering was not comforting, it had a quite square-shaped feel when changing sides. So generally lots of annoyance. I used two sets of these and put around 2000-2500 kms into a set before changing them. - Now I run on Pirelli P Zero Race TRL with Joe's sealant. Man it's a night and day difference. No flats at all, the tire grips and corners like crazy, cornering speed therefore skyrocketed. Comfort and speed does not feel worse than before. I have big (half to a centimeter) cuts here and there, yet the tire did not flat. I use 28 front 30 on the back. Currently I'm at around 1500 kms into my first set and a very very low sign of wear. Pirelli as a brand surprised me here, because in my experience their car tires are mediocre at best. I don't know how Vittoria's or Continental's performance tires would compare to my current setup, but I might give it a try just for the sake of experimenting, however there is a saying; don't fix what is not broken. So I can highly recommend Pirelli P Zero with Joe's sealant. Here is a link where tires seemingly get objectively tested: www.bicyclerollingresistance.com/
Pirelli are the best of the rest of the tubeless road tires that I have tested as my own guinea pig, (definitely superior to schwalbe, specialized and even the Hutchinson fusions). However the only tubeless road tires that I can totally trust are the IRC Formula Pro X-Guards. 25k+ miles on 5 sets with zero flats and extremely cuy-resistant. Fantastic grip from the rice bran infused tread with excellent ride feel and comfort. A true goldilocks tire that I have to keep a 2 yr inventory of👌
8:35 I like how Ollie explains it all in a most simple and elegant way about all the deep physics of it even tho there are many who teach even the simple things more complicated (my science teacher).
Yes really interesting “how deep physics” can go … ;-) … did he say that „… some energy is lost …“ ? That’s not physics that is wrong … energy is not lost but converted into some other form of energy or transferred from one body to another
Having worked a bike shop, Vittoria tires were routinley smaller beads than spec and a pita to install over Continental or Perelli as example. The times ive cursed this brand means I will never ride them. Glad the tour is on the marketing hype train of lighter faster better more expensive etc
@@colecoleman1499 Yes. Fragile, silly overpriced tires. IRC Formula Pro X-Guards for the win. Rice bran rubber =super sticky, plenty fast / superb ride feel, bombproof.
Looks like these are the uprated version of the Corsa N.EXT tires I ride on. Punctured on a large thorn from a mesquite tree, which usually results in a lot of cleat wear walking to home. Pulled it out as the twig it was attached to was hitting the frame and after a spray of sealant, I carried on. What's important is not puncturing, but when you do, having the tire seal properly.
Forget all of that, if they’ve solved keeping the tread attached to the casing that’s all the advance you need. I love Vittoria’s but every tyre I’ve ever had has come away from the casing long before the tyre is worn out
It’s important that GCN produces blatant, unashamed, advertisements like this one occasionally. It reminds us all that everything we see and hear needs to be taken with a pinch of salt. There’s a big list of the channel’s sponsors in the description under the video.
Notwithstanding the advertisements, some things are just very good, and if that can't be said, what can? It's not Vittoria's fault they produce excellent tires.
Got some. Fantastic. Already had some top end tyres on the bike, but curiosity prevailed. During todays ride I missed seeing a pot-hole until too late. The impact which would have guaranteed a snake bite puncture on a clincher. Here? Nothing. Actually stopped to have a closer look at what must have been some damage. No. Good as new. I rode on. 🙂
24 mm and 26 mm Corsa Pro tires can only be used on hooked bead rims, while 28 mm, 30 mm, and 32 mm widths can be used with both hooked and hookless rims. Hence whey most of the teams are on 28 because there mostly on hookless rims .
I gave up on Corsa Speed G1 (better because you can buy 23s that inflate to 25). They have batches that puncture too easily. Now use Conti 5000 STR which inflate to 26mm as a 25. Lost a watt or 2 combined of rolling resistance, but much better puncture protection
I mounted these tires just recently. During 160km ride, 16 punctures of which, one was major. Plugged it. Eventually lost all sealant in one but managed to keep air pressure in problematic tire to cripple home. When they are free they are great. At $90 each and the front has to be replaced after a ride I’m not sure they will be for 99.9999% of riders
16 punctures on one ride is a hellish sounding ride 😬 Where were you riding? Sounds like there could be something bigger at play maybe taking the wheel to your local bike shop would be a good idea. It's always good to get a fresh pair of eyes on these issues.
@@PeakTorque Ironically the only really good road tubeless tires aren't even used by any pro tour squad. I've tried all the modern tubeless brands and the only ones that have proven 100% reliable are the IRC Formula Pro X-Guards. Rice-bran infused rubber compound is ridiculously sticky, (wet or dry), ride feel / comfort excellent and in 25k+ miles on 5 sets, not a single f'ing flat. A proper goldilocks road tire, (even allows for plentiful 'underbiking' on NorCal's roughest of surfaces). It's a no brainer. No other tires have come close.
@@l.d.t.6327 they have a lower tpi then say a schwalbe pro 1 evo but are made far better quality and compounds. They don’t crack in under a year for example.
Olie, when I listen to you I feel like there another science, physics, chemistry geek who speaks the same language as I do. Geek = COOL! We are much more interesting than people realize.
Vittoria or Conti should be a Myer's Briggs personality type. I can just tell when i meet a Vittoria person. Dated one once and Mum said no, they would be unreliable.
I wanted to first say that I absolutely love a lot of the videos the GCN does. You guys have made great guides on bike maintenance and brought motivation to people. Unfortunately calling this “pros secret weapon” is a completely false statement, while ads have to be made. I found this one (especially the thumb nail) to provide false information. I bet these tires are fast just like the other ten top of the range offering!
@@Horstelin Right, not necessary. Though, at this price point it's guaranteed skinwall on Classics is painted, they emulated even look of uncovered casing. Brilliant! Assuming Sport is painted black....should there be any difference? Maybe....or maybe not.
The GP5000 is indestructible, Vitoria are known not to be, so until someone offers to follow my rides in their car with a spare wheel, that’s what I’ll be using!
We need to see the absolute values compared to other brands still. Do the teams run all the same width for all riders or do they deviate if a rider is very light or very heavy?
Nice! I've been using Vittoria Rubino Graphene Pro 28mm for a couple of years and really like them. I haven't had any flats on them at all. I run clinchers with tudes, I haven't gone tubeless yet, perhaps that's the next step. I will probably try these Corsa Pros on the next set of tires, or when the price comes down a little. Great video Ollie!
They're fragile af. IRC Formula Pro X-Guards for the win. Rice bran rubber sticks to everything wet or dry, great ride feel and utterly bombproof. Best darn tubeless road tires made for real world riding.
I run these in a 32c on my Canyon Aeroad with the DT Swiss ARC wheels that are 52/62 deep. I've compared them to a 25/28 combo of GP5000s on some Winspace 33D wheels over a 10 mile course and they were almost a minute faster. Not super scientific, but it was repeatable over multiple laps changing wheels. So is it the 20mm deeper wheel or the tire? 🤷♂
I'm getting old. I remember a time where 23mm where considered the comfy soft ride and we would bring out the 18mm for TTs cause they were so skinny and aero. Also hard AF!! 😅
The 'what width pros are riding' chat is irrelevant, as it is very dependent on rim width. 28c make a better interface on wider rims and 25c on narrower rims. Narrower is always more aero, providing the interface is optimised for both rim widths. Not to mention rolling resistance is only lower in wider tyres if pressure is the same (except for rough roads). Pushing tubeless meant wider rims/tyres to lower pressures so the sealant can do its job. If top of the range rims keep getting wider, so will pro tyres. My guess is manufacturers will keep fiddling with wheel specs, otherwise no one will buy new hoops. It used to be weight, then aero, then toroidal/dimples aero (since dropped), tubeless, wider, hookless, etc. Nothing against new technology when its purposeful, but I wonder if marketing isn't coming before advancements most of the time.
Right, let’s just cut the bullshit shall we? At the typical pressure you run a 25, 28, 30 or 32 the rolling resistance of the tyres are nigh on identical. Thinner tyres are more slippery than wider tyres. The reason Vittoria (and I like Vittoria, btw) made these tyres are because they didn’t have a cotton (or tan wall) tubeless or tubeless ready tyre in their line up, whereas other manufactures like Veloflex do. They needed a tyre for that particular segment of the market, the market being consumers who want this particular set up and aesthetic. End of.
Maybe the Corsa pro is lighter than ist predecessor, but with having already 265 gr form y favorite width 24mm, it is still quite heavy. A few days ago, I put a NOS Conti Supersonic 20mm (which has 22mm on a 13C/15C rim) on my rear Specialized trispoke; it has 142 gr, together with the Vredestein latex inner tube this makes nearly 200gr. Maybe wider tyres have a lower rolling resistance (but only with the same pressure as the narrower tyre), but a bigger frontal area, and as the rolling resistance increases linear, but the air resistance exponentially, don’t underestimate the aerodynamics. Still, it seems the Vittorias are faster than the Veloflex Corsa Evo black (205 gr /23mm, 220gr/25mm), or is it just because vittoria ist he sponsor?
Never using Vittoria ever again, their puncture protection is really bad if you ask me. I had them for a while but every like 100km i got a puncture. Switched to another brand and no problems anymore.
