Da würde ich gerne mal nen unabhängigen Test sehen, der das sauber ausarbeitet.

23mm innen... Da wirds unter 28mm Reifen schon fast komisch. Der wird dann auf 23 innen aber vermutlich 30mm breit?! Wie breit soll die Felge dann außen sein, damit es aerodynamisch taugt? 32mm? Und was hat man dann miteinander verglichen?

Bicyclerollingresistance hat übrigens zu dem Zipp Reifen eine interessante Feststellung gemacht:https://www.bicyclerollingresistance...speed-tubeless

We do have an issue with this tire and that's the very small tread that can be a potentially dangerous combination with some of the Zipp wheelsets that have a larger internal width than the industry standards (ETRTO). As we expect the only people willing to pay the price for these tires are people that own Zipp wheels and expect trouble-free operation, it's a big let down they didn't develop a tire made for wide rims.


As an example, we mounted the Tangente Speed Tubeless on a 22 mm internal width rim and found that at a static 45-degree lean angle, 2 mm of the sidewall will be in contact with the road. While a 45-degree lean angle is quite a lot, you also have to consider the road camber and surface irregularities when looking at the contact surface. On our standard 18 mm internal width rim, there was exactly enough tread to support a static 45-degree lean angle which confirms our suspicion this tire was developed with ETRTO standards in mind.


The 25-622 Zipp Tangente Speed performs well in our tests but just don't use it on rims wider than the ETRTO standards. The 28-622 version might be a better fit for nearly all Zipp wheels.
