Stack:
Reach:
The Stack and Reach Calculator based on height is an innovative tool designed to help cyclists find the perfect bike fit. This calculator uses a person's height to estimate the optimal stack and reach measurements for a bike frame. Stack refers to the vertical distance from the center of the bottom bracket to the top of the head tube, crucial for comfort and efficiency on the bike. Reach, the horizontal counterpart, influences a rider's position and control. By inputting your height, the calculator provides a personalized recommendation to enhance your cycling experience, ensuring both comfort and performance.
Formula of Stack and Reach Calculator Based on Height
The Stack and Reach Calculator simplifies the process of finding your ideal bike size by using straightforward formulas based on the rider's height. Here are the formulas it employs:
Stack Formula: Stack = 0.55 * Height Reach Formula: Reach = 0.45 * Height
Where:
- Stack is the vertical distance in centimeters.- Reach is the horizontal distance in centimeters.- Height is the height of the rider in centimeters.
These formulas are based on general ergonomics and cycling biomechanics research, offering a starting point for cyclists to find a bike that fits their body dimensions.
General Terms Table
To further assist users, we provide a table of general terms frequently searched by cyclists. This table includes common measurements and conversions related to bike sizing, offering a quick reference without the need for calculations.
| Term | Description | Example |
|---|---|---|
| Stack | Vertical distance from bottom bracket to top of head tube | For a 170cm tall rider: 93.5cm |
| Reach | Horizontal distance from bottom bracket to center of head tube | For a 170cm tall rider: 76.5cm |
| Bottom Bracket | The part of the frame around which the crankset rotates | - |
| Head Tube | The tube of the bike frame that holds the front fork | - |
This table serves as a quick reference to understand the key measurements affecting bike fit and comfort.
Example of Stack and Reach Calculator Based on Height
Consider a cyclist who is 180cm tall and looking for a new bike. Using the formulas provided:
- Stack: 0.55×1800.55×180 = 99cm
- Reach: 0.45×1800.45×180 = 81cm
These measurements suggest that the cyclist should look for a bike with a stack of around 99cm and a reach of approximately 81cm for the best fit.
Most Common FAQs
The estimates provided by the calculator are based on average body proportions and general cycling ergonomics. They serve as a good starting point, but personal preference, riding style, and specific body measurements should also be considered for a perfect bike fit.
Yes, these measurements are a fundamental starting point for all types of bikes. However, the ideal stack and reach might vary slightly depending on the type of cycling (road, mountain, triathlon) and personal comfort.
If your measurements fall between two sizes, consider your riding style and comfort preferences. For a more aggressive, race-oriented position, choose the smaller size. For comfort and endurance, the larger size may be better.
