28mm Schwalbe Pro One Tubeless on my Giant TCR - nice!

Sure. But that's typically too hard and is neither fast nor comfortable and not how I'd set it up. But, you're right - if you want to pump your tires up hard then you gain nothing by going tubeless.

I wouldn't of thought so.
Under that pressure starts to not feel good for hard cornering and sprinting.

That’s interesting. I weigh considerably more than do you and I ride at 66/70Psi and thought that might be a bit high and was going to drop it 5% or so. I also found a noticeable difference with tubes. Rode like a truck with tubes and very supple and connected without.

I have the Schwalbe Pro One 28's on my Giant Propel SLR one wheels. I had a hole to big for glue to seal so was going to remove the tire to replace or patch. I ended up cutting the tire off because I could not break the bead away from the rim..
Anyone know of an easier way to get that tire off the rim?
fyi. No trouble with the front wheel which is 17mm wide, rear wheel is 19mm wide

I’ve just fitted some tubeless 28mm Schwalbe Pro One tires to my 2018 Giant TCR (Advanced 1), and I’m very pleased with the results.
I was a bit concerned that the tires wouldn’t fit the frame, but my internet research proved to be correct: the 28mm Schwalbes inflate to just under 30mm @80psi and are about 26mm in height above the rim. This is on the 17mm internal width Giant PR2 rims.
There is about 3-4mm clearance to the fork crown at the front, and a similar distance from the seat tube at the rear. Clearance everywhere else is ample.
The ride quality is *way* better than the stock 25mm Giant Gavira tires. I had a near miss at a junction with those tires on a slightly damp road, when they had very little grip. That relegated the TCR to be a “dry roads only” bike until I found a solution. The Schwalbe Pro Ones apparently need about 60 miles / 100km “run-in” to get maximum grip in the damp, but they feel grippy to me even in the early morning dew-covered roads.
They also roll really well, feel great in the corners, and are really comfortable after the 25mm Giant tires.
I started at 85 psi, but found that to be uncompliant, so reduced to 70-75psi for my 72kg (158lb) weight. Below 65psi, the front wheel squirms a bit when riding out of the saddle, but would be fine if seated. These pressures make for a really comfortable ride that makes me want to use the TCR for commuting.
It isn’t all roses though; getting the tires on the PX2 rims was very easy - I didn’t even need tire levers. However, I couldn’t seat them with my track pump and had to go my LBS to pay for the privilege of them fitting the tires. It took them a while, even with a compressor. One tip they gave me was to do an initial fit of a new tire with an inner tube so that the tire expands to it’s final shape, and then remove the tube, and fit again.
The tire loses a bit more pressure during my normal ride than a 28mm GP4K II with a butyl tube, but I always check my tires before a longer ride, so this isn’t a big issue for me.
Time will tell if the puncture protection and durability of the Schwalbes is good or not, but they’ve given a new lease of life to my Giant TCR and I’m loving it!

I am considering upgrading my TCR Adv Pro 2018 to 28mm & would like to make sure I won't get any frame rubbing. I currently run 100psi and would drop the pressure to 90 or even less (I am a little heavier than the average joe
).My LBS told me 28mm wouldn't fit, but I know that some of them would. The Pro One is actually the tire I would like to purchase.

Keep in mind that since the OP, a new Pro 1 has been released. The new Pro 1, with Addix and the orange '1' sidewall logo, are smaller/more true to size on modern width rims. If you look it up, I think that they're made to measure out to the nominal width on 19mm internal rims, but do confirm for yourself.

Good to know. I don't have a digital caliper to exactly measure the current clearance, but it seems like I have between 3mm to 6mm (1/8'' to 1/4'') of clearance on each side of both my tires inflated at 100psi right now. Adding an extra 1.5mm tire width on each side might not rub if a 28mm stretches/widens as equally as a 25mm when inflated. I am sure this is not the proper way to determine that, but it's a good start.

You have 3mm of clearance right now? 4mm is the general minimum that manufacturers want to see for debris, etc, but it's not uncommon for people to cheat by a mm or so (which is where you're at right now). Get a 4mm hex wrench from your tool box and use it as a spacer to check gaps between your tire and frame. If you can fit the wrench and have 1.5mm excess, then you can think about sizing up within the same tire model.
I have 4mm of clearance (4mm hex fits snug) between my front tire & fork and 5mm of clearance (5mm hex slides in with very little play) between my frame & rear tire.
To be 100% sure, I would need to compare my actual tire width with the Schwalbe Pro 1 tire inflated. A 28mm will technically add 1.5mm on each side, but might ''stretch'' less than the 25mm since it's going to run at lower pressure? Not sure.

"Fitted easily and seem much more durable than the previous Pro1. A great tyre but 28 measures as old 25 so size up if you want wide tyres" .
I purchased a few 30mm P1 TLE Addix, but haven't mounted them yet. can't beat the price. https://www.merlincycles.com/schwalb...0c-187206.html

from reading the reviews on Merlin Cycles the newest version runs a little narrower.

I absolutely would not recommend anything over 80psi. We weigh the same, and on 30mm Schwalbe G-One Speed tires I use 60psi rear and 55psi in front.

That's what I was looking for. Yours are tubeless correct? To be clear I didn't mean to exceed 80, just that there isn't a range on the sidewall, only the max allowed.
