How it helps

Use it for a focused task

FitNote takes three body measurements and returns suggested frame size, saddle height, and stem length ranges. It covers road, gravel, and commuter geometry styles, explains what each number means, and lets you save or print a one-page fit summary.

Enter your height, inseam, and arm length. Pick a bike style.

Read the suggested ranges and the notes below them. Save your fit to the browser for later, or print the summary to bring to a shop.
