Just wanted to share my un-boxing, weighing, and first ride impressions of the new Schwalbe Pro One's I picked up the other day during a Black Friday Sale. I've been riding tubeless for a few years now and have tried three sets of Fusion 3's in both 23mm and 25mm and a set of the original One's in 23mm so I'll use my experience with them to compare the new set. Installation was a breeze with no need for tire levers and aired up with a floor pump. After the initial inflation I deflated them and added 30ml of sealant into each tire and re-inflated them to 100psi and called it a night. Upon waking the next morning I checked the pressure and they were both sitting right at 90psi which is a good indication all is sealed up well and felt good about my upcoming ride.

Sunday morning was go time and as soon as I got on the bike and up to speed I knew I was in for a good ride, the bike had a confidence inspiring feeling of being connected to the road with a much improved steering response and just seemed to accelerate effortlessly in comparison to my previous tires. I also couldn't get over how the bike just felt lighter, hard to explain? I know making a statements like that will make some of the tubeless haters call bull but I must say that the ride today was above my expectations and feel we've finally got a tire that will change the tune of anyone that's against the tech or has been hesitant to try tubeless. I did just come from a set of 25mm Fusion 3's that weigh almost 100g more each plus bought a new set of wheels about a month ago so there's a lot for me to digest when making a determination of the Pro One's performance but my first ride impressions were amazing and hope they prove to be reliable with a tread life that's as good as the original One's.

Below are a couple pictures of actual weights of both tires, stems, sealant, width measurement, and my new wheels just for fun. The wheel set weighs 1,477g, tires are 227g/228g, stems 8g each, plus 30g of sealant each tire for a total of 2,008 grams. I selected the 23's instead of following the trend to go larger because I seem to favor the ride of a smaller casing and I'm buying into the fact that wider is better when it comes to wheels. The 19mm inside bead width of my wheels gives the 23mm tire the volume of a larger casing without the weight penalty and measure 27mm wide inflated on these rims. Time will tell how well these tires hold up and I'll keep my fingers crossed for good results but my first impressions are outstanding!

one has to wonder what compelled the company to advertise the tire as 23mm.

PepeM

I'm sure I've said it before but those are nice wheels.

dvdslw

Thanks, I'm liking them so far.

Those are really wide rims though, 19 inner and 28 outer, according to the website. I wonder how the tires would measure on a thinner rim?

hueyhoolihan

ya, i suspect they measure the width of the carcass before the tread is applied, use their previous experience, and write up the ad copy, as for the rims they will be mounted to and what the final result will be? well... que sera sera.

So, 23mm tire measured as 27mm? Schwalbe you are drunk.

Campag4life

Guys,
A 23mm tire is going to measure wide on a wide rim...not rocket science.
Two...problem with a narrow tire on a wide rim is even tho internal tire volume stays the same, the vertical dimension of that volume is reduced which contributes to easier strike through and ride degradation...tho the OP in this case seems to like the ride.

OP...you didn't say your weight or what psi you run them at. This changes the balance of comfort. I would say most would prefer a 25mm tire on that rim...this is how tire sizing is trending...toward 25mm tire width on narrow or a wide rim.

Don't believe many will dispute a good ride and low rolling resistance from a top tubleless tire.
The issue is pressure leakage and installation...that is why many like myself prefer a tube for training in particular.

Nice wheel/tire combo OP and thanks for your review.

Even though the picture below is of different wheels, the one on the left has a 20.5mm inside width and the one on the right has a 15mm inside width but both have the same 23mm Continental tire mounted. I would suspect the Pro One's width to be close to 23mm on a 15mm rim.


Another reason why wider is better for a road tubeless application is to help eliminate the chance of the tire's bead coming unlocked under extreme cornering. With a narrow wheel your tire gets more of a light bulb shape and will move side to side when cornering which pulls at the bead as shown below.

Confidence, inspiring and effortless acceleration.
Good stuff lol

Since the tire is open at the beads, you really can't talk about its volume without considering the volume of the rim channel. The contained air volume of the tire and rim channel together is greater on the wider rim than on the narrower rim. That is why you can/need to inflate tires to lower pressure on the wider rim than the narrower rim.

dvdslw

First ride I went high on the pressure as a starting point with 95psi front/100/psi rear and I weigh 225lbs right now. Next ride I'll drop the pressure down to 85/90 and see how it responds. With my weight I can't go too low but even up near 100psi they felt good.

Campag4life

Good point Robert. Net of rim + tire = higher volume. Shape of volume matters as well of course..tire height relative to width as most of the principle force on tire when absorbing road disturbances is vertical to tire height matters...and all said a wider rim with a 23mm tire will be a shorter vertical distance to strike thru than a 23mm tire on a narrower rim even though the net volume will be greater on wider rim.

rpenmanparker 

With so many different width rims and with a tire being wider on a wider rim there is really no obviously correct standard anymore for nominal tire width for advertising purposes. It appears that tire companies are still using the width of a tire on a 14 mm inside width rim as the standard. How they will handle this size question as more and more of the rims in use become wider is an interesting question.

Campag4life

Pretty surprising you prefer a tire width of 23mm at your weight. To me, you are a solid candidate for at least a 25mm tire...27mm may even be better at your weight.

Campag4life

Kind of like frame sizing with sloping top tubes.

dvdslw

The way I understand it, as the bead gets wider the tire actually stays close to the same height or taller. The image below is from Hed and shows actual tire sizes on three different rim widths. These are real sizes taken from plaster molds.

I weigh 220lb and run 23c tubeless on 19.4mm BSW rim at same 95/105psi F/R that OP does. The ride and handling are sweet, fast.

rpenmanparker 

Yes, I hadn't thought of that, but it is a similar situation. Bye and bye the tire width will just be a nominal number related to some forgotten standard. Also like size 36 pants.

Thanks for the review, @dvdslw. You know I'm trying to hold out for the Vittoria Corsa Speed TL, but you make the P1 sound so tempting!

dvdslw

No problem, the Corsa Speed's look good too but reviews from their product testing has them looking like a race day only tire with not much in the way of flat protection?

chaadster

Yeah, you've mentioned that before, but I've not seen any kind of ride reviews on them yet, so I suppose I should look.

I should add, since the big news is the addition of graphene, the claim is superior puncture resistance and increased durability, but again, aside from the Vittoria marketing, I've not really seen anything by way of reviews.

Campag4life

Thank you for that pic. Live and learn. I would have thought there was a greater difference in tire height with the same tire on a wider versus narrower rim. Your picture shows there isn't much difference at all. Thanks for setting me straight on that.

PepeM

Mileage will probably be quite low though.

chaadster

Yes, at 205gm, there just can't be much tread depth on those things.
