GoodYear Eagle F1 SuperSport Road TIres

[Hexsense]

Vittoria Corsas are slower than GP5Ks, Yoln.

Right, but isn't it supposed to be faster than Turbo Cotton as well? I'm lost...

Bicyclerollingresistance.com says GP5k>Corsa>Turbo-Cotton

But here Cottons are better than GP5k...

Turbo Cotton doesn't have 25c. They have 24c and 26c. BRR round down and test 24c TC (which run closer to other brand 23c) against other 25c.
BRR use butyl tube while some other places use latex tube. Supple cotton tires might benefit more from latex tube.
Even roller drum diameter effect the test. Smaller diameter roller degrade the performance of supple and soft tire more than stiff tire.
All in all, from my experience using both on the same road, Corsa G2.0 is not faster than GP5K. It may have many good properties such as ride quality, side wall durability etc. But rolling resistance is not one of the advantage of Corsa G2.0 against GP5K.

I ordered a pair of 700x25 and they are scheduled to arrive tomorrow.

Please let us know your measurements including inner width rim size. Very curious. If they blow up to 28mm I'm out.

[robertg]

I'm running Roval CL50's which are 21mm internal. Once I mount them up, I'll pull out the digital calipers.

[Ypuh]

In that case they probably do blow up to 28mm+. I'm limited to 27mm width as measured, running mainly 17mm rims (404's) or 19mm rims. I also have some 21c rims but don't use them on this bike for this reason.

However your measurement is still welcome though. Some tyres blow up to 29mm+ on wider rims, which would indicate they come up big.

The Conti GP5k clinchers I have on there now measure 28.5mm front and 28.52mm rear. They could measure a little smaller or a little larger and I'm ok with it, but would prefer them to measure on the larger side of the Conti measurements.

[robertg]

Tires came in, they look great. Weighed them in at 195g and 203g, so heavier than advertised, but lighter than the Conti GP5k I was running, which weighed 218g and 225g. Both are 700x25.

But, mounted on the same wheels, Roval CL50's, the Goodyear's are definitely narrower. I put the lighter tire on the front and the heavier tire on the rear. The front measured 26.83mm and the rear measured 26.46mm. The Contis measured 28.5 and 28.52. So the Goodyear's are lighter but that's because they are smaller. Photos of the measurements are below.

The tires do feel great on the road. Even though they are smaller, the tire felt more comfortable on the road. They didn't feel any slower or any faster than the Conti's, but they felt more confidence inspiring taking corners at speed.

[Ypuh]

Having limited clearance, I'm very pleased to see those numbers. They'll probably increase up to another millimeter once they settle, but it's safe to assume they'll stay under 27mm on 17c rims.

Thanks and I'll give them a go once they become more widely available in the EU.

Wiggle has them now. I ordered the regular not supersport version.

[robertg]

Put another 58 miles on the tires today, and they have gotten a little wider, front is now 27.46mm and rear is 26.87mm.

Hi all,

Quick one on this. Has anyone tried the Goodyear eagle F1 super sport (CLINCHER, not tubeless) 25mm on 19c internal rim width? How does it measure?

I'd like to set them up on a 19/20mm internal rim width and 28/29mm external rim width. Wondering how well they'd do from an aero perspective.. From what has been written above, I can see they blow up to roughly 27mm on a 21mm internal rim width, so it should be more around 26-26.5mm on a 19mm int rim width.. would that be correct to assume?

Thanks!

After tiring of poor durability of Schwalbe Pro One TLR, I am looking at the Pirelli P zero race tlr (26's) and the Goodyear Eagle F1 supersport (28's). I ride 25's so I am not overly concerned which size (26 or 28) I end up with.

Anyone compare / ride both? I'd wait for tanwall GP 5000 but the prices are absurd. Puncture resistance, wear and holding sealant are concerns.

TIA!

Where are you all purchasing these in the EU? I can't find them on the common websites that come to mind.

P Zero TLR in a 26 @ Lordgun for vg prices.
