If you haven’t figured it out yet. I’m crazy about turbine/turbo/aero wheels. You guys all want fat lips and concave spokes… but I’m on the other side. Don’t get it? This is real 80’s race car style. …But it is only 80’s race car style… because using your wheel as a fan to SUCK air in to your brakes is a deprecated idea. Of course… the better alternative, is to pull air out (as seen in F1 and other series today), but that doesn’t matter because we are all wannabe’s and poseurs anyways.
The Zender Sport Disc was said to generate about 5psi worth of pressure inside the hub area at 75mph if a full sized backing plate was used. There must be something I don’t understand, though, because that sounds really worthless.
Of course, don’t confuse this idea with aero covers, simply designed to reduce drag at speed. Still cool IMO… and actually an idea that holds today!
PS> I’ve been lazy and haven’t updated my wheel database in a couple weeks… there is still lots to add.
