Conti all day long. Just a better tyre.

Swhalbe in the wet is not very good. Schwalbe on wet brick is completely unrideable. (for those navigating city streets with brick crosswalks).

I've ridden the Pro 1s for years and just moved over to a pair of GP5ks (tubeless for both). I find the Pro 1s a touch more supple as well as cheaper.

IRC Roadlites are good too.

obviously you've ridden both the 5000 and the pro one. i've got some pro ones on the way to me. i'll be riding them both myself. i'm wondering how you've arrived at your conclusion about these tubeless tire models.

Continental GP5000 TL tires are about $60 each.

I have a stellar track record with Conti as well as with the 5000 TLs now. Better aero and rolling resistance, but more importantly I find they seem to grip better in the wet and seem to be more puncture resistant. Both the lady and I are on 5000 TLs for 1000s of kms before I just replaced my first set. No punctures.

Punctured (and sealed successfully) on fairly innocuous roads with the Schwalbes. Obviously that can happen anywhere. At any rate, I did not care for them in the wet and they don't roll as well.

thanks. i'm just surprised you had the time to put 1000s of kilometers on 5000s, as they're a pretty new tire, and you also had the opportunity to put meaningful time on the schwalbe pro ones.

Again, myself and the lady are on them so plenty of k's on them.

Meaningful time on the Schwalbes is a no though. Wasn't happy with the puncture nor a back wheel slide out and so I bailed.

what wheels are you using for this?

we're going to start a new thread today, an evergreen thread just for road tubeless. you're on the leading edge of this. it's my view that road tubeless is where the market is going. i'll have my detractors, as i did when i pretty much staked out the position a few years ago that disc brakes were where the tri market was going.

we're starting the thread to help make it easier for our readers to make the switch intelligently.

Roval CLX 50

been on Schwalbe last 6 or so months... and GP5000s the last month or so.. sometimes alternating since they are on different wheelsets. I think the schwalbe are a tad more supple and soak up bumps a little better (they are wider and taller at the same pressure) maybe it's the rims that make me feel that way too. Schwalbe on Enve 4.5AR and GP5000s on Roval CLX50.

Speed wise they are pretty equal.. nothing huge between them.. my times are slightly faster on the ProOne on climbs.. downhills I have been getting PR's with the 5000s.. ? who knows. I never really had an issue with ProOne's in the wet and obviously since it's summer have not had the 5000s in the wet yet. Both feel fine on the dry to me.

I switched from Pro One's to TL 5000s a couple of months ago. I like both and am not sure I can really tell the difference on the bike. My butt does not to seem to be as well calibrated as some. Will probably stick with the 5000s simply because conventional wisdom seems to indicate they might be a little faster.

I can only speak to the pro ones. Been running that in a 28 for about 3 months on my road bike. I love it. 0 issues so far. As far as a road tire goes this is my tire of choosing for the foreseeable future.

Where? (I only checked Biketiresdirect).....

Interesting intel. In the past I rode quite a number of Pro Ones but also destroyed a couple of them (admittedly riding where they're not intended). Been really liking the Hutchinson Sector 28, which seems to be a skinny 28 (or more likely accurately measured) but of course that doesn't roll as well as 5000 or Pro One.

What's the internal of your Roval? What size tire are you riding, and how to they size on rim?

I want to say internally they are 21mm and 25 GP5000s are measuring fairly true to size (being around 26mm).

Rovals are indeed about 21.. specifically 20.7

After 3 years on Pro Ones, I switched to the 5000TL once the rolling resistance data was out. Prior to the 5000TL, I was an ardent Pro One evangelist. It's one big flaw - wet weather cornering - isn't much of an issue with me, as I live in SoCal and am super soft (i.e. never purposely ride in the rain). I can't say I notice much of a difference between them, though the Pro Ones have always been wide for their stated size and so a 23c Pro One is pretty close to a 25c 5000TL (the smallest 5000TL offered by Continental).

So TLDR, 4000SII was my "train/any race other than a TT" tire before the switch to tubeless, then Pro One with the switch to tubeless, but I think the 5000TL is the "Pro One killer" and now the best "train/any race other than a TT" tubeless tire.

Final note: 5000TL can't be used with hookless rims like Enve 4.5 ARs, so you will need to stick with something like a Pro One or Corsa TLR for hookless.

So.....Conti size wise.....

I have 2 sets of Reynolds Aero wheels which are 19mm internal and 28 external
The 25mm Pro Ones measure @ 28mm in these wheels. I could probably fit a true 29.....maybe a 30mm tire (could be tight).

Anyone measure a 28mm 5000TL on a 19mm internal rim? Staying close to the 28/29mm size?

Merlincycles.com has them for $62.

I've had the GP5K TLs on my TT bike since Nov and the Pro 1s on Road bike for about a year. don't ride too much in the rain (SoCal). find them to be pretty similar in terms of feel. hard to quantify speed since different bikes. But need a new set of road tires and going to switch to the GP5K since they feel more durable. have had multiple punctures recently on the Pro 1s. they sealed up ok but just feels like they are a bit more sensitive to that.

Just ordered a pair from Chain Reactions. On sale and found a 10% off coupon so out the door shipped for $102.72, plus 1.5% cash back thru ebates/rakuten. I would have just price matched @ biketiresdirect, but they did not have any 28's in stock.

in that case... i've been on road tubeless since feb 2016 and have not fixed a flat since then.

On HED Belgiums my 25 Pro 1s were 28/29. The 25 GP5ks on the same rim were 25.5.

$58 at sigmasports.com, who also give free espressos in their shops and are an all-round well run business (I hope they make money, too).

The Pro One's are lighter weight and have less robust sidewalls (by inspection - not sure what effect if any this has on puncture resistance). I've run and tested both and both are good tires, but I don't have thousands of miles of experience with either. I would never in a million years use Pro One's because they are very tight to mount on some rims, and seem to have a large bead which can make them near impossible to change in the field (again, on some rims). I once actually cut one off a rim with a carpet knife because I couldn't get the bead to release, at home in my garage with lots of tools at my disposal. It was cold that day and I think that made things worse, but still.

My last puncture on the Pro Ones was a sidewall cut (it sealed with Orange Seal) and has been holding fine since. I am crossing my fingers the 5000TL's are as easy to mount as my Pro Ones.....if not, I'll return them and just stick with the Pro Ones. On the Reynolds Aero rims - the Pro Ones will mount by hand (no levers needed) and remove easily with a single plastic lever so. I had a 2 sets of DT PRC wheels and they were much more difficult to mount (so I got rid of the wheels in favor of the Reynolds).

I have the 5000TL on my front CLX64, set up was easy. But it (5000TL) won't go onto my 321 (rim brake) disc, tyre dia smaller/tight, wheel rim tall. BTW I am a bike mechanic and have fitted 1000's of tyres so its not a technique thing :-)

'to give anything less than the best is to sacrifice the gift'...Pre

Another point of data I have almost 2 years and over 4600 miles on my Pro 1s with only one flat that didn't seal. That was a front flat from when I rode off the road into a culvert and my only exit was the ~6" right angle end of a curb and my hands were not placed well enough to allow me to hop onto it (I was eating when I rode off the road). To say I hit that curb hard is an understatement and I ended up with a small leak that seemed not to want to seal on the road. I put in a tube rode home cleaned the tire add new sealant and it's been good ever since.

The Conti is intriguing, but I've had such a damn good experience with the Pro 1 I don't think I will be switching. That and the Pro 1s are available at such a great discount. FWIW, I don't ride in the rain that much anymore, but I have been caught out plenty over the last couple of years and I don't feel like the tire lacks any in the wet weather traction department. But, maybe I'm just not that aggressive in the twisties. ;)

Also, someone I know who flats all the damn time has a full stock of Conti 5K TLs now and I'm curious to see how he gets on. So, who knows, maybe I'll switch too.

Full disclosure: most of the roads I ride have some seriously nice pavement.

What is your TL TT tire, VCS?

Schwalbe’s PO TL are terrible. Never had a puncture seal and after every ride there would be spots where sealant was leaking through with small cuts over the tires. I have about 300mi on the GP5k TL and the tires look new no cuts no sealant wet spots on the tires.

Technically I think that means you did have punctures seal. If sealant is leaking through, air would have much more quickly.

The tread is thin on the Pro Ones. Definitely more of a racing tire. But I had something like a 90% seal rate when I was using them. I'm just now trying out the GP5K TLs. They seem pretty promising so far. After that I'd put the Hutchinson Fusion 5 family a bit above the Schwalbe. But I wouldn't call the Pro Ones "terrible."

Yes the Corsa Speed seems to be fastest rolling tire and it seems that folks like Aerocoach are building their wheels around it to optimize both Crr and CdA, but unless someone tells me the 5000TL is a total dog in CdA, I think there’s a reasonable argument to be made that if you’re risk averse and don’t want to risk a flat (something that in my experience is not at all unlikely with the Corsa Speed), then maybe the 5000TL is the best choice even for a TT.

Of course, the best would be to test with your wheel on your bike so you can tease out how CdA and Crr shake out for you on your bike, but absent that it would seem these two tires would be the best place to start when choosing a tubeless TT tire.
