Key Measurements in Mountain Bike Sizing
Understanding the following measurements can help in selecting the appropriate frame size:
- Standover Height: The distance between the top tube of the bike and the ground. Ensure there’s adequate clearance (typically 2–4 inches) between the top tube and your inseam when standing over the bike.
- Effective Top Tube (ETT) Length: The horizontal distance from the head tube to the seat tube. This measurement affects your reach and riding posture.
- Reach: The horizontal distance from the bottom bracket to the top of the head tube. It influences how stretched out you feel on the bike.
- Stack: The vertical distance from the bottom bracket to the top of the head tube. It affects the handlebar height relative to the saddle.
