How to Measure Inseam
Stand with your back against a wall, legs slightly apart. Measure from the crotch to the floor. For the most accurate bike fit, your **inseam** is more important than your total height.
Pro Tip: Crossover
If you're between sizes: Choose the **smaller** frame for more agile handling (racing/technical) or the **larger** frame for more stability and comfort (long distance).
