Measuring RAAD on a bike
I’m enjoying the book Dialed: the secret math of a perfect mountain bike setup and really appreciate the MTB specific and rider-centric approach to bike fitting. I was wondering if you can guide me toward how to accurately measure my RAAD? There’s plenty of info in the book on how it should be set, but I’m not clear on the best way to measure it. Any recommended tool? Protractor devices and angle finders are generally not very long and would likely lack precision if trying to measure from the center point of the bottom bracket.
My RAD is prefect, surprisingly, with a fully stock bike (Large 2021 Epic EVO), so I’m afraid to tinker with the wrong adjustments and just end up messing up my RAD by trying to dial in my RAAD. Any tips on accurate measuring would be greatly appreciated.
Thanks in advance!
