What are stack and reach measurements and why are they important?
Stack is the vertical distance in millimetres from the centre of the bottom bracket to the centre of the head tube and Reach is the horizontal distance in millimetres from the centre of the bottom bracket to the centre of the head tube. Both measurements are taken from the same points on every frame making them the only reliable dimensions when comparing frames.
By using Stack and Reach to design our frames we can ensure that each size is proportionally larger or smaller than the size above or below it.
Traditional frame sizes are a bit like shoe sizes in that they can vary considerably from one manufacturer to another as not all bikes are measured in the same way. What one manufacturer calls a 56cm frame can be equivalent to a 54cm or even a 58cm frame from another manufacturer in terms of how their Stack and Reach measurements compare.
