Zipp Tangente ?
I have the Zipp Tangente tires. I'm pretty sure they generate wattage of their own. Negative friction, even. Dimples do that, you know.
Truth told, the Zipp Tangentes (clinchers) came with a set of wheels I bought. They're fine. Just like almost every other tire out there. They're a weird size (21), so they look narrow to me, but they're strong and support high air pressure.
I haven't run any other tires on those wheels, so I have nothing to compare them to, but I can't imagine the difference between tires would even be perceptible to a human (excluding the psychological factor).
Since they were free, I'll take the psychological factor. And the negative friction. But I'll save some coin and buy something else to replace them when the time comes.
Tires DO make a significant difference. Your tires aren't bad. The owner of my LBS is putting Armadillos on his Zipps (I've tried to convince him it's a terrible idea, but he won't have any of it). As long as you're running a 21mm-ish race tire, you're fine.
My personal favorite is Vittoria Corsa Evo KS (just about the lowest rolling resistance you can get without getting a track tire or something with zero flat protection). The Zipp tires are made by Vittoria.

Not fast enough.
Thinner tires will have lower rolling resistance, lower rotational weight, and a narrow profile to cut through the wind....so yes, size matters.




So I was reading one of the Tri mags the other day and it was talking about how you can have aero wheels but if you have the wrong tire that you may be loosing advantage of aero wheel. I currently have Zipp 606 with Tufo S3 Lite Tubular which are $65. The mag gave some good feedback on the Zipp Tangente but they are very pricey. Anybody have some feedback on these tires and are they really worth the extra $$ ?
