Glad this makes you feel a bit better. I actually took mine out on a 73 mile ride over the weekend that had a stretch of about a half mile on gravel. No punctures!
Yep these tires are great and I too highly recommend them too. They are definitely fast! A test that I always do when I put on new tires is free-wheeling down my local decent and these travel much further than any of the other tires I've used in the past. My ONLY issue with them was the difficulty to seat the tires on my Zipp wheels. I think it could have been due to the condition of my rim tape. There was one point I had spent almost an hour or more and I finally gave up and threw on a set of used Pirelli P Zeros and they seated on the first go.
Glad you’ve had a similar experience to me with how fast the tires are. But, I can’t say that I had the same issue seating them. They were no harder than normal tires for me. But I didn’t seat them on my Zipps, but my Hunt wheels. I’ll report back if I install them on my 303s and have any trouble.
I’ve never had a (fast) setup where I didn’t need to inflate before every ride. I’m quite picky on pressures and if it’s 0.3 bars off, I think I can feel it. The only setup that holds air super good is a thick and heavy butyl tube, preferably used on the lower end of the declared tire widths spectrum. 🙂
A lot of times, this is true. I do think that tubeless technology and sealant technology is improving. But you're right, the best retention is definitely a thicker butyl tube.
Great follow-up ! I wonder if the air retention problem is related to high end , high thread count cotton, or poly-cotton tires. It seems most reviews of tubeless tires of this type have this problem. I have been using road tubeless a long time and my vulcanized butyl tires never seem to leak down air like that. Thanks, Dave
Thanks Dave. I really do think that’s it. I think it’s a matter of high TPI cotton casing tires as opposed to vulcanized rubber. I’ve also been told that the Muc off sealant I use may not be as good for sealing up the casing. Good for punctures in my experience though. I think it’s just the price to pay for that supple fast tire. Thanks for watching and commenting!
Great review - Looks great, is it worth using theese tires with tubes. Im a new rider looking for some speed, but aint ready to go full on tubeless yet :D
I think that’s absolutely a good idea. If you run a tube that’s low rolling resistance such as latex or TPU you’re going to be in the same ballpark. Just plan to run slightly higher tire pressures to prevent pinch flats. And if you decide to go tubeless later, you’re ready.
Yeah, I agree with everything. I would say the sealant dries up relatively quick in these tires compared to others that I've used. Not quite Rene Herse bad, but it's up there.
Factory installed tape, hooked, and yes it was seated. The leakage was through the sidewall. If you watch the video on my channel on the corsa pro control, I actually was able to catch it on camera.
@@JMCyclingVideosThank you good to know. Am riding a giant tcr with hooked rims, always conti 4-5k tubes, but thinking tubeless now for comfort, will likely go conti 5k.
The GP5000 are great tires for sure. I would give the nod to Vittoria when it comes to comfort but they don’t have the leak down issue. Either way, you can’t go wrong.
Hi ! Thank you for this feedback. I intend to buy these 32mm tires with the Silca sealant which contains these carbon fibers. I imagine the combo of the two should make the tire very durable and also avoid these pressure losses.. Have you had the opportunity to test this Silca preventative? Thank you for your answers.
I have not tried Silca. I’ve currently only used Orange Seal, Muc Off No Punctures, and Stans. Feel free to drop another comment here and let everyone know if Silca helps to seal them up. I plan on getting another set in 32mm so if the Silca works for you, that may be what I get next.
@@JMCyclingVideos Silca is my go-to sealant over Orange and Stans on my GP5000S TR tires. All sealants seems to stop the leak. But Silca seems to stop it much faster.
Does the Silca have large particulates? One benefit I liked about orange is that there were no large particles so it could be sent through the valve. I don't do that if the sealant has large particles as it would defeat the purpose if they couldn't fit through the valve.
@@JMCyclingVideos they have two sealant options. One with large particles and one without. Their thinking is you use the one without particles to top up your sealant.
Hi... looking for your guidance...i have a giant defy and i plan to do 80% road and 20% gravel... gravel being rail paths....what is your opinion on the Vittoria corsa control 34 vs schawlbe g one rs 35 ?
Hard to say really. I haven’t used the corsa control tires, but if your rail trails are as smooth as the ones near me, you’d probably be OK with a wide road tire with good puncture protection. I wouldn’t use the tires in the video though, the corsa pro tlr as they’re too fragile for anything more than the shortest and smoothest off road stretches.
I’ve been told that’s the case by more than one person. Really that’s my only gripe with these tires. I only switched away from orange seal endurance which I used for years because I had some bad cuts at Unbound and wanted to have better sealing for larger holes. You live and learn I suppose
@@JMCyclingVideos yeah I recommend the standard it’s the better of the 2. Be warned it drys up pretty quick, but it’s good at its job, i put in 50-60ml for the first seal and just top up once a month with 30-40ml depending on how much is left in the tyre. My gp5000 str only go down 1 psi every 12 hr. And I can live that. Far better than 10psi of latex tubes in a 6hr period
Excellent to hear! I don’t mind topping up every now and then as long as the sealing is good. Minimal leak down like that isn’t bad at all. Appreciate the recommendation!
@@JMCyclingVideos well alrright, that doesn't change the fact that 1000-1500 miles is nothing and shouldn't be called "long term" especially when you run any modern tyre, they should last minimum 2x/3x as much without any worries.
I understand your mindset but there are also a lot of people out there who still run certain wheels and tires for race only. And for those, 1500 miles is more than they’ll see on a set
Different people different need and miles per month 😂 I commute on them someone race on them. 1k my monthly number😂 Thanks for video 👍🏻 very informative
i just bought myself a pair that i plan to use all season long. they haven't came in the mail yet but this video makes me happy about my purchase

Don't blame the tire blame the rim. Zipp is shit. Hookles shit

Glad my review matches your experience. I think a cotton casing tire is just more susceptible to it in general.
Great review. What action cam are you using so you can can add speed and power indicators ?
I use a GoPro and use the Garmin VIRB application to overlay data from the Strava file.
Thx, in terms of leakage, who installed the tape, and are you using hooked or hookless rims and are you sure bead seated ?
Factory installed tape, hooked, and yes it was seated. The leakage was through the sidewall. If you watch the video on my channel on the corsa pro control, I actually was able to catch it on camera.

@@JMCyclingVideosI understand, but like convenience: the possible extra maintenance of the V’s would bug me !:)

Muc off would be your problem with the air retention. I’d be using orange seal with those. As I do with gp5000str

@@JMCyclingVideos I’m mean the regular version the endurance stuff isn’t much better than muc off in all honesty
Interesting. So do you recommend the standard? If so, I’ll probably get some on order as I’m almost out of sealant.
@@JMCyclingVideos yeah I recommend the standard it’s the better of the 2.

great tires but had to set them with tubes (tubolito)....after 1 unsuccessful full afternoon as tubeless on my Zipp 303s....
What was the issue with being tubeless? Did they just leak down or did you have some other issue? I’m curious.
❤
Thanks!
You'd put 1500 miles in 9 months and you call this a "long term" test? What do you do, cycle every other Saturday? LOL.
I average 4-5000 miles per year. Not all of those miles go on one bike or one set of tires.
