I’m not surprised a lot of people chimed in recommending the CH aero cover, but I wonder how many of them actually have any experience with the product and are just repeating the party line they have read here. I’d take YabYum’s advice and not try to make the CH cover work with your Ks. The covers make more sense if you have an extra box rim training wheel around, or have a powertap.
If you are committed to the sport, I’d look to the long term. This year, buy the Renn disk. Then you’ll have a rear wheel that is petty much as good as anyone really needs. Then next year I’d save up your money and watch for a fall or winter coupon sale and buy a good front wheel new when you don’t need it. The prices on ebay aren’t usually spectacular enough to justify the risk of getting second hand wheels. In the end you’ll have great equipment that you won’t regret.
You certainly can use the K front with a disk rear, nothing wrong with that. While Ks certainly give up significant performance to a true aero wheel, the difference is not going to be as large as some make it out to be. (Check the tech section of Zipp’s site for some aero test of the Ks. This year, you can comfort yourself with how much better your Ks are than a 32 spoke wheel. Next year, you can comfort yourself with how much better your new front wheel will be than the K.)
Also look to the long term and decide if you want your race wheels to be sew up or clincher. Clinchers really are fine performance-wise, but if you’re a weight weenie you’ll probably never be happy unless you go for the sew-ups. If you decide sew up, then get the sew up disk. You’ll have to carry a spare tube and tire irons as well as a spare tubie, but this extra ¼ pound is no more than the extra weight penalty you would have had with the CH aero cover instead of the disk. And you can use one of the tire irons to help peel the tubie off the rim if you have a flat on the rear.
