Don't let the funny spelling fool you; this is a good brand! They're less expensive than Zipps but I've been really pleased with my pair and the customer service. (For example, let them know you're from DC Tri and get a free t-shirt, since one of their staffers went to GW.) For those of you who aren't sure if carbon race wheels are worth it, from my experience you can't tell much of a difference under 18-19 mph, but then it's a big boost of 2-3 mph.
If you use the code KTSPEED you can get around 28% off your purchase. (Code can be used multiple times.) They also offer payment installment plans and can pre-load tires for you, if you're as mechanically un-inclined as I am. -- Katie
