I wouldn't buy "off" brand carbon clinchers if you live in SoCal and ride the mountains we have here. Doing the 4 mile descent down the switchbacks of Mt Baldy on Boyds or Williams (or almost every other carbon clincher) would be risky to me. It's *hard* on the brakes for a couple miles there. Only carbon rims I'd take to the top of Mt baldy are Zipp Firecrests or rims with an aluminum brake track.
If you're not doing twisty descents, I say go for whatever is more aerodynamic. Zipp posted some tests for the 101's against the competition, maybe check out slowtwitch or zipp.com for those results.

A power meter will benefit many, many riders incomparably more than a modestly aero wheel. Excellent point!
I didn't mention this before because my wheelset budget didn't allow for a power meter and garmin. But $1000 is getting there, especially used.

I don't understand the humour. It's certainly possible to quantify the difference in drag between different wheels but requires careful procedures.

Indoors it would be feasible at a velodrome. Certainly a windtunnel is a good test.

I didn't say it was easy. You need to do it early in the morning before the wind picks up. It has been done successfully outdoors.

to be honest i don't "NEED" anything or "hope to gain" anything. I just appreciate a good riding, somewhat lightweight wheelset. The idea of a wider rim is also appealing. Sure I could do just fine with my stock R500's, but where's the motivation, where's the fun?
The main thing reasoning for me going with something like the zipps is that I really would like to purchase through my LBS. It's nice to have the peace of mind and convenience of just bringing my bike/wheels in should anything go wrong or if something is out of true. They look at it, do whatever needs to be done, and I walk away happy with not a cent extra paid. They've treated me well ever since the new bike buying experience and I'd like to continue that relationship. I just can't imagine walking in with some brand "X" wheelset I bought, expecting them to help me when I downright purchased online simply to save a few bucks. That being said, shimano RS80's, mavic ksyrium SL's or similar are going to cost me upwards of 900-1100 bucks retail. At that pricepoint, I'd rather spend a little more and get the Zipps.

Good point. The HED Ardennes's look very atractive as well.

For the non-luddites who are interested, aerolab is an effective tool for estimating CdA.

You seem to be taking this guy's wheel purchase rather personally. Any reason for that?

I suppose you're one of those who doesn't believe in evolution either. Scientists are often required to make intelligent conclusions with incomplete information. Powermeters also measure power based on estimates of multiple variables.

Dude, give it up - meaningfully assessing the aero properties of a single component based upon power meter data is ridiculous.

You can actually get very good data from virtual elevation and aerolab. It has some limitations but can produce great results. It's so funny that people are so quick to dismiss outdoor testing when we all ride outdoors. Yet wind tunnel testing is considered to be gold even though it's a very controlled situation trying to predict what will happen in the relative chaos of outside weather.

I recently got the 101s on ebay for about 899 dollars. They are stiff, and handle REALLY well due to the width. I took it up kings mtn last weekend and loved them on the ascents and descents. Plus the hub noise is zipptastic. I can't say that I've tried boyds or other bang for buck wheels, but I don't think I'll ever need another alum or carbon set based on my experiences in the past few months.

To me the purpose of tunnel testing is not to predict what will happen outdoors, but to define the coefficients for the accepted model that then can be used as a predictive tool. It is the gold standard for getting the data to determine the coefficients. The middle step tunnel->parameters->model is important.
