The Stack and Reach Fit Calculator is a valuable tool for cyclists aiming to achieve the optimal geometry for their bikes. It calculates two crucial dimensions, Stack and Reach, which play a pivotal role in determining the comfort and efficiency of a rider on their bicycle.
Formula of Stack and Reach Fit Calculator
The Stack and Reach Fit Calculator employs the following formulas:
Stack = (Head Tube Length + Headset Stack) - (Top Tube Length * sin(Head Tube Angle)) Reach = (Top Tube Length * cos(Head Tube Angle)) + Stem Length + Handlebar Reach - (Headset Stack * tan(Head Tube Angle))
Where:
- Head Tube Length: Length of the bike’s head tube.
- Headset Stack: Stack height of the headset.
- Top Tube Length: Length of the bike’s top tube.
- Head Tube Angle: Angle of the head tube from the horizontal.
- Stem Length: Length of the bike’s stem.
- Handlebar Reach: Reach of the handlebars.
