New calibration ride....look ok?

Post by hakuna »

Hey,

I got my new cadence mount and went out and did 10 coastdowns, followed by my 4 mile out and back on a relatively low wind day. My roads are rough here and the Crr came out to .0090 That's after tossing the 4 highest and one low oddball coastdown. Seems a bit high right? Anyhow, I'll post my ibcd4m file and a ride file I did later the same day (today) in hopes that someone can take a look for me. Coach Boyd?

Thanks in advance,
Gary

sorry, I've been traveling a ton recently. I was going to take a look at this and then it slipped my mind. When I get to the hotel tonight I'll take a look.

Your crr looked a little high, and your cda was a little low. I changed the crr numbers to a more real world number and let it effect the cda numbers.This raised the cda to what I would expect it to be (and it matched really closely with the cda from the other profile from before).

It's attached here for you to look at.
