That's REI's attempt at mass marketing its bikes. Bike fit is something to be done by a mechanic and is a function of your inseam (or distance to pubic bone), torso height, arm length and what type of riding it will be.
It's something you'll be doing thousands of repetitive motions on, not a t-shirt.
