Gravel Bike Size Chart — How to Choose the Right Size

Why Size Matters More on Gravel
Gravel rides are typically longer than road rides (2–6 hours common). A poor fit causes back pain, numb hands and knee issues. Gravel bikes also handle more demanding terrain, so a stable, confident fit is essential.
Key Measurements Explained
- Reach: horizontal distance from bottom bracket to top of head tube. Determines cockpit length.
- Stack: vertical distance from bottom bracket to top of head tube. Determines bar height.
- Standover height: minimum clearance over the top tube — important for off-road dismounts.
- Effective top tube (ETT): horizontal length from seat tube to head tube.
