1. What is Mountain Bike Reach?

Mountain bike reach is the horizontal distance from the bottom bracket to the top of the head tube. It's a crucial measurement that affects bike handling, comfort, and performance, especially as riders age and their flexibility changes.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Height \) — Rider height in centimeters
• \( Age \) — Rider age in years
• 0.47 — Base adjustment factor for height-to-reach ratio
• 0.2 — Age adjustment factor per year below 50

Explanation: The formula accounts for both rider height and age-related flexibility changes, recommending shorter reach for older riders.

3. Importance of Proper Reach Measurement

Details: Proper reach ensures comfortable riding position, better control, and reduced strain on back and shoulders. Age-appropriate reach is particularly important for maintaining riding comfort and preventing injuries.

4. Using the Calculator

Tips: Enter your height in centimeters and age in years. The calculator will provide a recommended reach measurement in millimeters for optimal mountain bike fit.

5. Frequently Asked Questions (FAQ)

Q1: Why does reach change with age?
A: As riders age, flexibility typically decreases, requiring a more upright riding position with shorter reach for comfort and control.

Q2: What is a typical reach range for mountain bikes?
A: Reach typically ranges from 400-500mm for most adult mountain bikes, varying by frame size and bike type.

Q3: How does reach affect bike handling?
A: Longer reach provides more stability at speed, while shorter reach offers quicker handling and more upright position.

Q4: Should I consider other fit measurements?
A: Yes, stack height, stem length, and handlebar width also significantly affect bike fit and should be considered alongside reach.

Q5: Can I adjust reach on my current bike?
A: Yes, reach can be adjusted through stem length changes, handlebar rise, and saddle position adjustments.
