New Michelin Power Cup Tubeless: GP5K S TR competitor

[Yoln]

Not sure how legit is the "Independent Testing" by Wheel Energy, but comparing to GP5K S TR:
- same weight
- 0.1W better rolling resistance
- similar puncture protection
- and apparently a much better cornering grip

Could this be the new king of race/crits?

I only see results for the clincher + standard weight butyl tube in the BikeRadar link. Let's see results for the tubeless version...

The king of crits is the Corsa Speed.

I don't know where you race crust but here in the northeast your puncture probability with corsa speed is probably >50% per race. I love them, but only for TTs

I assume you're saying "probably" because you've never tried it. I have, and the roads I race on are almost certain worse than anything in the NE. Pump your Corsa Speeds up so you don't damage the sidewalls running over cracks and trust the sealant plug punctures caused by other detritus. Though yes, if you want a little bit more piece of mind, the GP5K S TR are also fast... almost all tires are effectively "equal" in terms of dry grip.

Here is part of the Merced Crit course which was just run last week. Advance through a few paces to see the road surface get worse and worse.

Main takeaways vs GP5K S TR. .1W really doesn't really matter. Weight is the same. Puncture protection is the same. Cornering grip is good enough on any tire in the dry.

Why doesn't .1W matter? Because the test is done at very specific settings. Because wear level, temperature, road quality, etc. can swing the pendulum back and forth. Because only the clinchers were tested...with thicc butyl tubes. Who's caring about .1W and also using ~100g butyl tubes? Literally no one.

Buy whichever tire of the two is on sale and less expensive at any given moment.

If these inflate as “oversized” as Vittoria Corsas, I’m in.

The 20g weight reduction from the Power Road TLR strongly hints at the tires being narrower than those.

A tyre which is launched with already an "independent test" showing that it is 0.1w faster than the main competitor.. I'll remain skeptical - let's see if BRR confirms it.

That said, the Power Road TLR is the very only tyre that I had to return as I was not able to fit them, they were both gnarly to mount and then they just wouldn't pop onto the rim. I've had a fair share of GP5k's, but those were far more of a pain. Truly hope these would be easier.

Has anyone proposed it to BRR?
I have used up my vote on the new Pathfinders .

The 25c clincher and TLR are already there for voting. I already voted for the American Classic Timekeepers for the month.

I wonder if the 25mm vesion of the Power Cup will be approved for use on 23mm inernal width rims. The 5000 S TR and many other tires are not. Many f us with 23mm internal width rims will be looking for this info.

[Elmersen]

Now that the new ERTRO allows for 25mm on 23c, isn't a bit strange that some manufacturers don't? Will we ses a change for GP5000 S TR?

The test result indicates the used Wheel Energy https://www.velonews.com/gear/road-gear ... esting-it/ Smooth roller and higher pressures, so the numbers will be more favorable to tires with more durable sidewalls. The bumpy rollers and lower pressures highlight more compliant sidewalls.

Looks like this is power road, with a TL bead and less rubber . In any case, the numbers are inline with their current offerings. I assume they are just reducing SKU count, sacrificing longgevity, and making their tires hookless OK.

If they help to put pressure on the Continental Grand Prix 5000 TR prices, that is a good thing. They are still at 70€
