Conti GP5000 clinchers

Just bought some 28mms on sale & mounted them on Boyds 44 carbon clinchers. They went on very easy if not easier than the GP 4 Seasons & GP4000s I've used do. Mounted width measured right at 28mm- the 25mm 4 seasons measured just under 28mm on the same wheelset. I pressed both tires flat on a table & measured the width of both- the 28mm 5000 miced 3mm wider than the 25mm 4 season. Looks like Contis statement about these being truer to size is accurate.
Won't ride until this weekend I'll give a ride report after riding them 500 miles or so.

Love my 28mm GP5Ks. Haven't had any issues mounting them and they ride and handle great. Mine measure at 30mm on my 20c wheels.

I have a GP5 on the rear wheel and a GP4 on the front wheel, I don't think you need to "upgrade" since the differences are literally imperceptible but if you have to replace your GP4s anyway, might as well spend a few extra bucks per tire for newer technology.

Here's an interesting comparison-

https://www.bicyclerollingresistance...prix-5000-2018

TL;DR- The GP5000 has slightly better rolling resistance, slightly worse puncture protection, and slightly higher weight (at least for the units sampled, the claimed weight by Conti is lower for the GP5). They're both great tires.

Running a 5000 on the front while I kill my last 4000 on the rear (clinchers). They are nice.

You may not have a choice: I tried to replenish my closet full of spare GP4000S clinchers last month and nobody had them in stock! Had to "settle" for GP5000s ...which were on sale, so yay for me.

I've got about 3K miles on my GP5000 32mm tubefuls that I put on over the winter. There is still some of the wear indicator dots showing on the rear, no flats yet. I'm thinking I will get another 1k miles on the rear one. I really like them for my road bike and they were by far the easiest tires to get on that I've used in many years. I'm kind of a baby going downhill in rain but the GP5000s did very well on a ride where I got stuck in heavy rain on a hilly route for over 30 miles.

But, 4K miles for the price is kind of expensive. On my touring bike I have Schwalbe Marathons that cost less and I seem to get twice as many miles with no flats. Hard to see apples to apples rolling resistance data between the two but I looks like the Marathons would cost me about 7 watts per wheel at the 80 psi I run. Of course, I could lose a pound or two pretty cheaply...

Has anyone mounted the gp4ks and gp5ks on the same rim with the same psi? Just trying to figure out if they over inflate to the same size as the gp4ks did. My 23mm 4ks inflate to 25 at the psi I wanna run on my bike and rims and my bike can’t handle more then 25mms in the back.

You can get some info from BRR on this. Quick data.. their tested GP5 23mm tubed version measured out at an actual 24.4mm on a 17c rim. and FWIW, since 25mm tires are the base tested model and only model where you can get historical data, the GP5 measures 26mm on 17c rim, while the GP4 at 27mm. Not that this necessarily means they built the 23mm tire a bit narrower or not.

25mm GP5Ks are pretty close to 23mm GP4Ks. These were all mounted on the same rims (21c):

23mm GP4K - measured 27mm
25mm GP5K - measured 28mm
28mm GP5K - measured 30mm

I have GP5k on my 2003 ti bike. I've gotten ONE flat and it was from a piece of wire so small I had to get a pair of tweezers to extract it. It didn't cause a flat as much as it put a smaller than a pin hole leak in the tube. I don't know that gatorskins would have stopped that one.

I have over 1k mi on them and they are nice and grippy. They're better tires than I am a rider.

I started out incredibly aggravated with my GP5 tubeless. I had I think one of the earlier batches (installed first week of February). Harder to get on than what I’ve become used to, and they would throw cords all over. I’d cut them off and after one or two more rides another would start this was on both wheels. Eventually that slowed down, I liked the ride and was incredibly surprised the other day when I realize they had almost 3000 miles on them which is probably 800 more than I’ve gotten from any other tire. I just replaced them today, never a flat but getting pretty square at the top.

i like to experiment with new tires so I’m giving the Vittoria corsa super G a try. They are very light, and very thin. I hear good things about the ride quality but I can’t imagine them lasting long. We shall see, but I’d definitely do the 5k’s again

Update: First ride repoort

Put @ 56 miles in this morning on the new GP5Ks. Noticed immediately they ride smoother than the GP4 seasons they replaced- most likely due to a little more volume (28s vs. 25s) and the softer sidewall. I'd say seat-of the-pants very similar to GP4Ks I've used in the past. Rolling resistance? Well I really can't tell if they're 12% less than the GP4Ks or GP4 seasons but they certainly aren't worse. Time & miles will tell of their durability. Happy with the way they ride but again if they hadn't been on sale for $39 ea. I wouldn't have paid full retail price for a set.

My experience, 5000s aren't overinflating like the 4000s did. 4000 28mm was massive mounted (never measured, eyeball) compared to the 5000.

For those of you had both. Are 5000s easier to mount than the 4000s?

I'll have to look at the 25mm on the GP5000 when I need to replace my rear. I put a 25mm GP4000 on the rear of my bike and I couldn't get it to not rub unless it was perfectly centered and even when I did center it, by the end of the ride it shifted enough or maybe it was under load that it was just wide enough to rub. Anyway I had to put it on the front and keep the 23 on the rear. After a year of riding with the 25 in front though the rubbing caught up with me and it blew out the side. I replaced it with a 23mm GP5000. Now I'm going to need a new tire for the rear pretty soon anyway so maybe I'll try the 25mm in the rear, but also ready to swap back to the front. These things ain't cheap.

Haven't had any issues mounting either one, I've never even used a lever, but maybe I just have strong hands? lol When new, I lay them in the sun for a bit to soften them up, once they're broken in, I've had no issues getting them off/on.

Anyone measure a 23mm yet?

I'd be interested since I'm light enough that it doesn't bother me and if the width is truer may sell some of my older tubular TT gear to go that route.......GP5000 clincher with latex.

I'm sure a true to size 23mm on a 21mm wheel would be faster/smoother than a 19mm tub on a 19mm wheel.

Switched from Michelin PRO4's to GP5K clinchers this year. They are very similar, but the Conti's can finally corner as well as or better than the Michelins. I've had three flats on the GP5K's, all from unknown sources. Like SCTinkering saw, it was a pinhole leak...but I was never able to find the culprit.

I have 5k clinchers and can mount them on Zondas by hand with no levers, without too much effort. They roll nice with Conti Race 28 tubes (not the Race Light version) and I've had no flats or complaints. 75 psi front, 85 rear on 25mm with a 160 lb rider weight. Never had a flat actually. So now I will since I said that, lol.

Do you have the inflations backwards? ie. 85 rear, 75 front?

I liked mine at first, but not so much now. Maybe it is bad luck, but I have had several flats now in only 1k miles. They are also wearing as fast as the Vittoria Corsa G+ they replaced, which never flatted and cornered better. The rear is cut up quite a bit through the cords and I need to replace it already. I ride the same roads regularly, and these have been the least durable tire I have used so far.

Never seemed to have an issue mounting either, seem the same to me, pretty easy all around. Some wheels suck for mounting tires.
