i'm not sure what your drive is to find the old model, but the 5000's are a better tire in every single way and are found on sale often...

I agree that the new ones are better. I like the new ones quite a bit. However they changed the width and a 25 mm 4000 is just about right. I think a 28 in the new version would be too wide and a 25 in the new version might be too narrow.

bicyclerollingresistance.com measured the 25mm GP4000 at 27mm; and the 28mm GP5000 at 28.5mm.
Thats 0.75mm per side.

My go to tires for years now. 25s mostly but they run big. I only have one road bike that the 28mm GP4Ks will actually fit. And actual Team Issue Roubaix Domane Classics.

I only recently got some 28mm TL GP5000, and some 25mm non TL 5000s. I can not tell any difference rolling. Except the 5ks run more true to size. My 25mm GP4s are bigger than the TL 28 GP5ks. The 25s more like the 23 GP4Ks, maybe 1-1.5mm bigger?

I have Six NIB 25mm left on the wall. I expected the like the 5Ks better and sell them off from all the drivel I read about how much better they are. I am keeping my 4Ks for sure.

On the 28mm 5K TLs, I think they ride like a 23mm old Schwalbe one Tubeles, expected better regardless of the lower CRR on a drum.

I liked GP4’s. But if you can’t find any, I am having good luck with Michelin Comp Power’s in 700x25, which measure just about 27 on C17 rims.

I like the Pro 4 Service Coarse 25mm too, have some of those left new on the wall as well. They don't roll like the GP4ks though. Casings even more generous in size, and I have not flatted one yet somehow. My road winter tires for when GP4ks seem to flat more for me.

If you read the rollingreistance.ste CRR site for them VS the GP4ks, and the roller actually has any comparative reality to rolling on the coarse pave I ride mostly, you will be 10 MHG avg slower or some such.. I exaggerate...

I was reluctant to mention it, as I don't intend to let any go.

What is your zip/local, I may be able to liberate 2 used ones early if you are getting nowhere. They be the 1st versions, not the II ones later versions. Not that I could tell a difference.

I may even have a VG used 23mm pair.

EDIT: What about Old_Fat_man invite to PM him for a new pair?? Because I don't actually have any used to liberate upon looking, My friend Scott got those a few weeks back now that I recall.

I’ve got three pairs of 25mm I’d be happy to part with. 10 dollars a tire?
