Find Your Frame Size

Grab a tape measure, and let's do this!

Measure your barefoot inseam. This is most easily done by standing with your back flat against a wall, putting a book between your legs, and pulling the book up tight against your sit bones. Measure from the top of the book down to the floor. Using the chart below, check that the frame size you're leaning toward has a lower standover height than this measurement.

Measure your shoulder width. It's helpful to have a friend assist you in taking this measurement. Have them measure the distance between the two protruding points on the front of your shoulders. Convert this measurement to millimeters and add 20mm. This is your approximate handlebar size, rounding up if you are in between sizes.

If your height falls between two sizes, first confirm that both have adequate standover for your inseam length. If they do, you have two options:

1. Size up and run a slightly shorter stem. By allowing a more upright handlebar position and shifting mass away from the front wheel, sizing up can improve comfort on the road and confidence in the dirt.
2. Size down and run a slightly longer stem. By allowing a lower handlebar position and shifting mass toward front wheel, sizing down can enable the more aggressive position preferred by some racers.
