Wheel Tunnel Testing at Texas A&M

Nestled in the small university town of College Station, Texas, the Oran W. Nicks Low Speed Wind Tunnel had an undeniable reputation in the 90's and early 2000's as the place to go for cycling related aerodynamic research.  With a test section that measures seven feet wide by ten feet tall, adequate flow qualities, and dedicated cycling fixtures, this facility was convenient for industry outsiders while still providing quality data.  Tunnel director, Jorge Martinez, has claimed that the wind tunnel balance will provide force data that is accurate to +/- 0.05 lbs.  While not as accurate as is desirable,

Campy vs Shimano

E-mail Print PDF

The debate has raged for decades about which brand is superior in the bicycle component group manufacturing business. Shimano and Campagnolo make component groups that provide the same basic functionality to a bicycle – transmission, steering, and braking systems. However, each company has several different priced offerings available. In short order, the whole component selection process gets complicated leaving the consumer wondering ‘Why Campagnolo’, or, ‘what exactly am I paying for when I buy Dura Ace instead of Ultegra’? It must be remembered, however, that they are simply bike parts and if consumers stick to these two companies, they will rarely be disappointed.

Editor's note 09/01/2010: for an updated ranking of current wheels using some of the criteria outlined below, check this BTR page out...and now back to your regularly scheduled reading!

 

The well-oiled marketing machines in the bicycle industry are constantly touting the latest and greatest technology.  With so many different brands available and broad-sweeping claims made, we consumers can often times become confused.  In the next few minutes, I will help you wade through the facts and provide some unbiased data on the high-end wheel offerings.   In the end, it should be possible to determine exactly what you get when you spend $800 on a set of the hyped-up high performance wheels.  However, we first need to investigate how I approach the wheel selection/evaluation process.

Wheel Performance

Sir Isaac Newton proposed his second law of motion nearly 350 years ago. This law elegantly describes the behavior of many systems, bicycles included. It is difficult to argue with the analytical results of this equation. It is my goal to use Newton’s law to demonstrate what variables determine wheel performance and their order of significance. Furthermore, I will show how wheels rank in the big picture of overall cycling performance.
