What is Mountain Bike Reach?

Mountain bike reach refers to the horizontal distance from the center of the bottom bracket to the top center of the head tube. It is a crucial measurement in determining the size and fit of a mountain bike. A longer reach can provide more stability and control, especially at high speeds and on steep descents, while a shorter reach can make the bike feel more agile and responsive.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ R = (600 + 720) - (7 \times \cos(7^\circ)) = 1320 - (7 \times 0.9925) \approx 1313.05 \, \text{mm} \]

The Mountain Bike Reach is approximately 1313.05 mm.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ R = (580 + 700) - (10 \times \cos(10^\circ)) = 1280 - (10 \times 0.9848) \approx 1270.15 \, \text{mm} \]

The Mountain Bike Reach is approximately 1270.15 mm.
