Here's a pretty interesting but brief discussion on the effects of crank length. As well as a preview of a new carbon crank.

You will find no high quality data to support any particular crank length as being better than any other. This is true whether or not you correct for leg length, femur length, etc. On the other hand, you will find lots of anecdotal or low quality data to support all kinds of conclusions, and more theories than you can shake a stick at. A rider's response to changes in crank length is 1) highly individual, 2) dependent on riding style and the event (TT, climbing, crits, track racing, etc.), and 3) most important, highly adaptive. This is why it is so hard to study the effect of crank length.

This guy is stating as fact something that is only his theory and has not been backed up by objective data. Easy to do, but of very little value.
