The new 1080 is Zipp's deepest rim yet with a (surprise) 108mm-deep toroidal profile. According to Zipp, the 1080 is 29 seconds faster than a three-spoke wheel over 40km while also boasting an 80g weight advantage and the same crosswind handling characteristics in the process. More interestingly, Zipp also says the 1080 is actually faster than a disc wheel up to a 13° yaw angle.
Zipp probably meant to refer specifically to other manufacturer's disc wheels, though, as it also says its new Sub-9 disc achieves a negative drag figure when equipped with its updated Tangente2 dimpled tubular tire. According to Zipp, the Sub-9 produces -80g of drag at a 15° yaw angle, effectively yielding 11 watts of forward power. Shapewise, the Sub-9 almost looks to be an 808 toroidal rim blended with a small-diameter flat disc in the middle. Naturally, just about every surface on the Sub-9 is graced with Zipp's ABLC dimples.
All of Zipp's tubular carbon rims will now also incorporate reinforcing bands of Kevlar fibers stitched into both impact edges. This so-called Carbon Bridge technology is said to offer the most impact strength of any carbon rim construction and also improves lateral stiffness.
Da muss man gar nicht mehr treten wenn man genug Geld hat (die werden sehr teuer sein).

ich meinte eher die pauschalaussage ohne beruecksichtigung des fahrers/rades/geschwindigkeit etc.
"According to Zipp, the 1080 is depending on the circumstances roughly 30 seconds faster than a three-spoke wheel over 40km" klingt halt nicht so gut.
Holger Meyer schaut sich da die Ergebnisliste vom Waldheimer Kurztria an und sieht, dass er die Top10 in der AK um 25 sek. verpasst hat. HED's in den Muell treten, Zipps kaufen.
