Why These Measurements Matter
Stack: Stack height refers to the vertical distance from the bike's bottom bracket to the top of its head tube. It affects rider posture and comfort. A higher stack provides a more upright position, ideal for longer rides or riders seeking comfort over aerodynamics. A lower stack offers a more aggressive, aerodynamic position suitable for faster-paced gravel racing.
Reach: Reach measures the horizontal distance from the bottom bracket to the center of the head tube. Reach influences how stretched out or compact the rider's position is on the bike. A longer reach suits taller riders and those looking for a more aerodynamic position, while a shorter reach provides a more upright and comfortable riding stance.
BB Drop (Bottom Bracket Drop): BB drop is the vertical distance between the bike's bottom bracket and the ground. It affects stability and handling. A higher BB drop leads to greater stability and clearance over rough terrain, making it suitable for technical descents. A lower BB drop enhances agility and responsiveness, ideal for nimble handling on smoother gravel roads.
Chainstay: Chainstay length measures the distance from the bike's bottom bracket to the rear axle. It impacts a bike's stability, handling, and weight distribution. Longer chainstays promote stability, especially when carrying loads. Shorter chainstays improve maneuverability and make the bike feel more responsive.
