    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 β€” important for off-road dismounts.
    • Effective top tube (ETT): horizontal length from seat tube to head tube.

    Brand-Specific Sizing Notes

    • 3T: Italian sizing tends to run "long and low" β€” a size M 3T fits like a size L from other brands. Check our 3T Exploro Ultra sizing.
    • SUNN: French sizing runs more compact. Look at the SUNN Venture S2 geometry chart.
    • BH: Spanish sizing is closest to industry standard.
