|Anyone had any experience with Aero wheel covers? I'm guessing this just makes your original wheel into a disc. If it works, its a great alternative for us who don't have the dough to flop out on a disc wheel we'd only use a couple times a year.

|... I've never used 'em but I thought I'd put this info on the table.
Many HPV racers will fabricate their own covers over conventional spoked wheels and like them... however, along with the weight penalty, you should note that true disc wheels have a specific lenticular shape or are flat which are (between the two) considered to offer the greatest aerodynamic advantage for a rolling bicycle wheel. It's possible that the more conical cross section of a spoked covered wheel could actually generate more parasitic drag than an uncovered wheel...
A bit more on the table... while I have no first hand experience with them (I run a ZIPP and HED Superlite), and they're still a pricey specialty wheel... consider Renn (One fast bud uses one (like he needs it)).
Remain In Light.

|Hed has a disc for $500 and I didn't think anyone could go lower than that.|

|I may be a tad off but last time I checked, the renn was 320. From what I understand, the hub is made differently than hed and others. it has some type of bolt that connects the hub to the disc. I've heard good stuff about renn though.|

|I rode with a wheel cover in triathlons many years ago. They did add a fair amount of weight to the rear wheel but it was faster overall. They were a pain in the butt since you had to peel part of the cover back to inflate the tire and you could break off one of the little plastic hooks that the cover fit into. I graduated to a "real" disk and then on to a J-disk, a spoked wheel covered with mylar (I looked on the web and couldn't find any reference to the J-disk today). I feel the best wheel today is a carbon fibre tri-spoke wheel that is almost as fast as a full disk without the handling issues. I have been riding a pair of Nimble Crosswinds for 3 years now and have been very satisfied. I wish I had them when I was competing in triathlons.|| |
