When I was sized to my first high quality road bike in 1984 it was simple: stand over the bike, lift it up to make sure you had an inch or two clearance, and you were good. Then choose between a 10 or 11 cm stem. Done!
Things got a bit more complicated with sloping top tubes in the 90s.
But things have gotten downright weird in the last ten years or so, especially with mountain bikes.
About five years ago Lee McCormack published his theory of RAD on PinkBike. What is RAD? “The Rider Area Distance (RAD) is the imaginary line between your bottom bracket and the centers of your grips.”
I’d ignored this whole RAD thing up to now, but after two years of riding a Large Ibis Ripley that feels too cramped for me, I measured my RAD yesterday and it helped confirm that I need more reach (for many people, though, RAD will indicate your are riding a bike that is too BIG).
