Thanks for sharing. Based on those results, the GP 5000 will likely become my new "go-to" tire. IMO, the very minor total wattage penalty it sees to the GP TT is offset by its markedly increased puncture protection.
Edit: interesting, the French site has the tubeless GP 5000 tire outperforming the clincher GP 5000 with a latex tube. Not by much but I still find that interesting.
They are different tires though. I think a better test would be the 5000 TL setup tubeless vs the 5000 TL w/ latex tube.
Actually, no. IME, testing road tires with a latex tube results in the same Crr as with it set up tubeless.
That's the reason I don't bother testing them set up as tubeless.
Which is exactly my point.....
I'm not sure if I understand your point then. You are saying above that a test of the TL tire with and without a latex tube in it is somehow
better than comparing the clincher w/latex vs. the TL?
The former doesn't give you much new info (i.e. they will test ~ the same), the latter tells you if you gain anything running the non-TL w/latex vs. the TL.
I get where you are coming from Tom. You make a valid point that the original test may be better. But I'm merely trying to point out that a tubeless tire setup tubeless is NOT any faster than with a latex tire in it. Your corsa speed test proved that but there are countless people out there that still think a tubeless tire is faster. Mostly due to the marketing of TLR wheels and tires.
What I'm wondering is why do they even make a non tubeless version.
Because tubeless + inner tube will be heavier and less performing than standard + inner tube.
Not even sure tubeless alone will be better than standard + latex inner tube (apart maybe self healing capability from sealant). This comparison will be interesting, because up to now, from the serious comparison I've seen, the tubeless do not win. But it will come. Will it come with GP5000 ? May be.
But for sure tubeless + inner tube better than standard + inner.... no
And non-tubeless is ... mmmm... more than 90% of the market.
Why make a competitive product for 90% of the market... instead of a non-competitive product.... mmmm ,,,, wondering....
From what I see the tubeless tyre with latex tube is 2 watts faster. not calculating.,how hilly a course has to be to make it slower than the non tubeless due to weight, but I imagine it will be a lot of hills required
I would imagine that for most the heavier tubeless with latex tube will be faster.
I guess the reason they make the non tubeless is purely for the reason that conti believes most people are to stupid or lazy to use latex tubes ( they might have a point there but still it's not performance in my mind it's more an "Ignorance" tyre)
I don't think many people have complained that vitoria speed is only avaialbe in tubeless version.
I guess I'm coming from this point as I never use the 4000 as for me it's to slow for racing and to expensive for training.
