I have an ongoing experiment to see if tubeless will get me toward flimsy roady tires like the grand prix 4000, so far jury is out although I know I trust my tubed marathon supremes for the conditions I have to deal with. I definitely like the sealant just autosealing punctures w/o making me even pull over to reinflate. Don't like the longevity of the tires (schwalbe one) but it could be a worthwhile tradeoff, haven't decided. Also really didn't like spraining my knee after a tubeless tire burped on me brought me down hard and fast. Spoke w/ some friends who ride tubeless and they have also had experiences that increase their caution and steer them away from certain brands (hutchinson!!!).

So I see that a lot of people are on the Pro One's and a handful of others on Fusion's. I got my new wheels and I'm ready to take the plunge.

So for me, I want a tire that is similar to the GP 4000SII's since I've been on them for a while now and they are awesome. I also race a bit so I need to have confidence when racing. I prefer to not ride in the rain so I don't need to worry about that.

So Pro One? Fusion? Something else?

I can't speak to them personally as I haven't used them, but the IRC Roadlight should be worth a look. It's often overlooked, but from what I've read is a mix of performance and durability, perhaps similar to GP4k2.

My experience with tubeless is that it works best in lower pressure applications. Recent testing has shown that 32mm+ tires with 60 psi can be a very fast setup and tubeless excels in this applications. I think road tires are going where mountain biking and cross have already gone: low pressure, wider more supple casings and tubeless is just better in many ways.

Also, the most frequent problems with tubeless are caused by people using non-tubeless-specific rims and tires. Use the OEM, designed for tubeless stuff and you'll be fine.

Where did you buy that pliers?

I've seen the BBB stuff in Europe often; the tool model is BTL-78. It's on Amazon coming out of Japan, but Google shows it available from some EU shops, too.

Anyone wish to share their knowledge to explain or clarify?

My current perspective, tubeless does not provide benefits for roadies on group rides in my area (we have potholes, gravel but no extraordinary issues like goat weed). However there are a fervent handful who have drank the Kool-Aid and swear by tubeless. (My issue and observation: at least 4 occasions in past 18mths, the self-sealing tubeless did not "take" and we had a BEAR-of-a-time getting the gunk clear to install tube).

Question: Any benefit to a tubeless-ready rim (no spoke holes) while still using rim tape, tube and standard tire (sans the sealant). My cursory understanding (belief) would be a lower incidence of pinch flats. Only benefit (not enough to tip the scales for me) if the roads are wet, and you want to maximize traction by riding a lower PSI).

Thanks for that. They seem to have good reviews but many have stated that they need to have higher pressures to be effective.

The S-Works Turbo tubeless look good as well, but really expensive.

How many miles do you think you get out of your Pro Ones?

chaadster

Yeah, I'm interested in the S-Works Turbo as well! You may know that was designed by the lead engineers who were at Continental and responsible for the GP4k, so it may share some of the same design priorities, but I have no idea.

As for mileage on my Pro Ones, I've yet to wear a tire out, but I don't expect much. I got about 1.2k miles out of two Ones, so if that's any indication of what the lighter P1 will do, it doesn't auger well!

My first P1 took what would become a terminal cut in the first 60 miles. It sealed and made it to about 200 miles before it reopened, bigger than the first time. I don't know if it took another trauma at the location, or if the sealant (and bit of KrazyGlue on the tread) just couldn't hold. I have a new P1 on there now, so hopefully I can take this one full use.

BigPoser

Yup I had seen that Specialized hired the old Conti guys. Not surprising that now they are making some of the best tires on the market. Your mileage doesn't seem to be a lot of miles to be honest. I could certainly see them for racing, but since my race season is over, I'd probably want something that was a little more hearty. Maybe the IRC's or the Hutchinson's would be a better choice. I've also heard that Bontrager R3's are decent although can be tough to get on the rim.

chaadster

No, it's not a lot of mileage by my figuring either, although I am 225lbs, and sprint and brake hard often, which are factors in wear rate and which I neglected to mention. Probably a lighter, less aggressive rider could squeeze a bit more out of tread life. Still, you know there are some tires you just can't wear out...!
