Big one to flag that’s sure to be controversial: Pro One Addix TLE actually tested (marginally) faster than the GP5K TL
Welcome all views.

Maybe it shouldn’t be controversial at this point since that corroborates the bicyclerollingresistance data.
BRR has GP5K TL at 8.9 and Pro One TL at 11.2 (100 psi), consistent with aero coach results.
They didn’t even test the fast tires… but I guess it’s intended for the masses not the CRR weenies.

Ah, I was looking at the TT version. I blame Schwalbe for having names that are way too complicated.
Ya totally valid point. Only thing I would add, is if they are on Crr par, the 100g savings on the pro one on longer courses with a bit of climbing might be a factor. Plus it’s also just interesting to see such different results. Heard some speculation that Schwalbe may have tweaked the pro one since roll out.
BRR rates the puncture resistance of the GP5000 much higher though. If we were comparing the faster Schwable tire vs the continental, would you choose 1.6 watts faster (for 2 tires) or double the puncture resistance (whatever that actually means?)
RoadBike found the same on puncture protection. Guess the Q is “how much puncture protection is enoughâ€. Also pretty consistent findings that the Pro One family is more aero (1-2 watts) than the GP5K family (aerocoach, parcours) of tires.
Oh, I have not seen the aerocoach data on the scwalbe tire…

The TT has the same structure/casing as the normal pro one, so would assume same aero profile.
Also parcours has similar results, but large grain of salt as the deltas (particularly at 0 yaw) between tires just don’t seem plausible. Could because their two tests were conducted a year apart:

Schwalbe Pro One TT is very aero. So much so in fact that in very windy conditions, on our Zephyr front wheel (78mm) a 25mm Pro One TT is as fast as a Corsa Speed (23mm or 25mm). As the Schwalbe TT is more puncture resistant than a Corsa Speed it is a great backup combination for windy days or terrible road surfaces. On our Titan (which is deeper at 100mm, and isn’t as wide externally as the Zephyr) the Schwalbe TT isn’t as good and the Corsa Speed beats it (in both 23mm and 25mm). It does depend a lot on what wheel you’re putting it on.
These are our recommendations for tyre choice for racing/training based on aero and Crr data, in order of real world speed:
Of course there are others in there like the Michelin, Pirelli, Specialized, but that’s our simplified recommendation list. As stock on our wheels we supply Veloflex, Vittoria, Continental and can supply Schwalbe if people want them but we thought it would be better to make it even easier to understand (Veloflex for best, Vittoria for best tubeless, GP5000 for everything else).
How do these new tires test against the old school Continental Supersonics? I have a couple of these still new in box. I only use them for racing and they last quite a while for supposedly fragile fast tires.
I’m really happy with the new Schwalbe TLE, so far they have been very durable and they ride nice. I’m tired of wrestling with the GP5000Tls. Glad to hear the new Schwalbes are close in rolling resistance.
Xavier, really interesting observation you make about the puncture resistance of the pro one TT vs corsa speed. BRR had the corsa well ahead of the pro one TT on this score, but if I recall he also flagged that real world resistance was a bit of an open question. I take it that your experience and those of your clients is that the pro one TT holds up actually quiet well (in relative terms, of course)? Probably not that relevant for this crowd, but the pro one TT also comes in a 28 (the corsa does not), if you ever wanted to through a 28 on the rear.
To finish first, you must first finish. Choose wisely- unless you’re in my age group.

Yeah, it got to the point where I started commuting on Pro One TTs to try and puncture them because none of us could in training. Eventually managed it on a patch of gravel, then it sealed and I carried on. Not something you’d be able to do with Corsa Speeds! Grip is fine too - I haven’t personally had issues with either the Corsa Speed or Pro One TT for grip but I know one of the world tour teams don’t like the Corsa Speed for grip, they race faster than I do however 
That’s great to know!!! I have a set of ENVE AR 4.5s and wanted to run it with a very fast tire in some cases (crits, longer road races). Corsa Speed isnt approved by ENVE (and doesn’t even come in a 28, the minimum tire size for them). But had heard the pro one TT was VERY fragile, so figured I was out of luck. So this is very good news!

Why not? I’ve twice had Corsa Speeds puncture-then-seal in TT competition.

Ah I don’t mean the sealing, I mean the amount of mileage on bad surfaces

Ah, gotcha. I agree that Corsa Speed effective mileage is low.

Yes I think that would be a great option. I was about to recommend the GP5000 as it’s not too far behind but that’s not an approved tyre for the 4.5s either.
