Bike Geometry - Head Angle and Bottom Bracket Height Explained

Published on October 8th 2015


How does bike geometry affect how your mountain bike handles? Click here to subscribe to GMBN: Head angle is how far your fork slants away ahead of the bike. Downhill bikes have slack head angles for stability at high speeds, while XC bikes are a bit more upright, allowing for better steering agility. Bottom bracket height is a big consideration in mountain biking. A lower bottom bracket will mean the bike corners better, but the likelihood of striking a pedal on the ground increases. You need to take into the amount of sag on your suspension when taking BB clearance into account. Music: Labyrinth Ear - Humble Bones (Instrumental) Click here to buy GMBN T-shirts, hoodies and more:
