Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

This will all become quite relevant when Continental switches from RRP/MSRP to MAP. While there are exceptions, generally even $50-60 is too much for a 700x25 tire. The profit margin has to be absolutely Walton-esque.

Trying to compare the value of a bicycle tyre to a car tyre is as pointless as comparing the value of a bicycle to a car.
The market will determine what price it will stand and the manufacturers/retailers will adjust accordingly.

MAP is Minimum Advertised Price. It doesn't prevent bike shops or online stores from discounting the price. Online stores must advertise the price as per the MAP agreement, but they can show the discounted price after the shopper puts the item in their "shopping basket." The good deals will still be available, but the shopper will have to do more work finding them.

I am sort of wondering after all is said and done about arguing about the price of these tires and comparisons between the cost of bike tires vs car tires if anyone is as interested as I am about:
A) Continental has introduced a new high end tire that they feel is enough of an improvement over its class leading road tire which has nonetheless been continually been improved for over a decade that they have designated a new model name for it.
B) They have for the first time also produced a road tubeless version of that tire
For my part, I haven't used Continental tires on my bike for many years. Nothing against them, I think that they make great tires. For years, I was able to buy Hutchinson tires at wholesale prices. I was an early adopter of Road Tubeless when Hutchinson was pretty much the only choice. However, once things settle down price wise, not only would I very much like to try the tubeless version of these tires, I would probably also think about using the standard clincher version on my other bike. Continental has only made a mistake by not making public the information about their tests of the tubeless version on various tubeless wheels. I currently use Hutchinson Fusion5 tubeless tires with Campagnolo Shamal 2Way fit wheels and once they are (easily) mounted, they hold air at least as well as conventional butyl inner tubes, even without using sealant. My Shamal wheels, without sealant have not been used for almost a month. When I gave them a pinch test today, I figure that I could still ride them if I were careful

I thought I was the only one tight enough to do the same. If it holds air it's good to go. I'm gonna ride it till the cords pop on the back. Then put the front on the back and do the same. I'm a natural born cheapskate.

If the "technology really there" means, "Does the technology work?" Absolutely. Tubeless tires work. In the absence of flats, they require regular maintenance that tubed tires do not. But, on the other hand, they do seal small punctures immediately that, on a tubed tire, you would have to stop and fix/replace the tube.

But if "technology really there" means, "Does the technology perform better than a tubed tire?" The answer is much less clear cut. For some tires/wheels, you can say that it does. For many (most) other tires/wheels, it really doesn't. And part of the answer depends on how you ride and what you want from your tires. You have to shop well to find a setup that's really better than what you have. Just because it's tubeless doesn't mean it works better (or doesn't).

Tubeless is not a free lunch, it's a trade-off between unscheduled road-side fixes and scheduled at-home maintenance.

If I got one or two flats per year, there's no way that I would bother with tubeless. If I was a CO2 user, I would probably bump that "wouldn't bother" threshold up to a puncture per month or so (I really don't like wielding a mini-pump on the roadside). As it is, though, I feel that the trade-off works very favorably for me, and I don't see myself going back to tubes.

YMWV, so consider how happy you are when it comes to addressing flats and the rate at which you get flats. Compare that to somewhat more difficult mounting of new tires (and the frequency at which you replace those tires), and the highly recommended sealant level check every 6 weeks or so. However the scales tip in your situation, that's cool, but there's no need for smug condescension either way.

I think that paragraph condenses it pretty well. For those of us who don't have minor punctures very often, the benefits of tubeless are hard to get excited about.

But tubeless does appeal to the tinkerer in me. I enjoy doing bike maintenance. So, in a perverse way, my 4- to 6-week sealant checks/top offs are almost a benefit of tubeless.

How about apples to apples? A Schwalbe Pro One can be had for about 40 bucks.

I've been using tubeless pro-ones (is there any other kind?) for over a year now and love how fast they roll, but can't stand how fragile and how short tread life is. I've tried others but keep coming back to the pro ones because the others just seem soooo heavy. I'd love to find a tubeless road tire that rolls well, but is more stout and lasts longer, so I will probably give them a try.

I've always had tubeless tires on my recent road bike so I don't understand the cult like following that the Conti 4000's have so I'm interested in trying them.

If interested, at ProBikeKit, buy 3 GP4ks II's, use their 10% discount and free shipping, and the tires are less than $31 ea.

I'm in EXACTLY the same boat as you. I'm running pro-ones and like the tyre but man, they are sensitive. I too don't understand the group love/metnality of the Conti's but figure now that there is a tubeless version out I might as well give them a try when my pro-one's give up the ghost. Presuming of course the cost is too prohibitive.

I've love to find another alternative to the Pro-ones.

i maintain it has very much to do with their ubiquity (vocab word of the week). Every (and I mean every) LBS around the NYC area seems to sell Conti tires and have a display of such.
Sure, the spesh dealer will also have spesh tires. The trek dealer will also have Bontragers. You have to hunt though for specific dealers that sell eg. Vittoria, Michelin, Pirelli.
On a related note, perhaps give the Pirelli tubeless tires a shot.

@Sy Reene the mentality also extends to the forums too. Just look at the threads here for example. But hey, if it's a good tyre people will ride it and rave about it.

Bicycle tire performance does not scale all that well above $50USD/tire in my experience.

The GP5000s at or below $50USD?

Not likely.

I saw the mavic Yksion UST tires are more light. I tested yskion UST 28C 2019, bought from ebay...very ceap,. I used 25ml of sealant and the tyres keeped pressure atfer 1 week, amazing. And the felling it's greate, rolling resistante as well. before mavic I useded conti S2.

I used an mtb conti TL and after 1 season with them I can say the tires are a bad joke...in a race they loose pressure..2-3h ride...

The issue is mostly price i cant afford a shwalbe pro one at 80 bucks a tire 1 hole and it will never seal or work right again.?so i get them at 40 ish . merlin has the gp4ks2 a pair is like 60 something Now . and thats just mouth watering.

A race/ training tire should not be over 50 bucks maybe 60 usd.
The gp4ks2 is hands down the best tire out . i cant think of any other tire i would use . maybe the corsa gs at around 40 usd . i could give the ultra sports a try at 15 bucks if picked up a set of spare wheels .
the crowd is pretty decided on what the best tire is . thats really the point conti makes these new claims but in the it will be tested by the masses and id put money on the tires being worse based on everything getting worse . giving people a better tire isnt going to benefit the customer it will benefit the company .

Thats a very cynical attitude to have. Conti have done well to position themselves as the maker of the best road clincher tire out there (and with the Gatorskin as well, arguably the best commuter/bad weather road tire too). Thatís worth a lot in terms of branding. Theyíd be doing themselves a disservice to negatively impact their customers with the new tire.

Not or saying you wonít turn out to be right, but just that it is far from a guarantee.

I just took took delivery of a pair of 4ks, and have an unused spare in my garage, so itíll be a while before I need to try the 5k. Iíll be keeping an eye out for the reviews as they come in.
