Hi there.
I've been playing around at analyticcycling.com, and I was wondering what values people use for parameters such as:
- Frontal Area
- Drag coefficient
Any pointers to websites with more information on these details?
I have looked around a bit, and found some stuff(I currently use 0.5 for Cd, and 0.7 for A) but was wondering if there was more information out there.
As these values affect the Power calculations substantially, I want to get them right. Any good methods to determine them from test WITHOUT a wind tunnel, or power meter (i.e. coast down a known grade, observe max speed, calculate CdA for 0 power, or something similar)???
Cheers,
Rob
