Trail Formula:
| From: | To: |
Trail is a measurement in mountain bike geometry that affects steering stability and handling characteristics. It represents the horizontal distance between the point where the front wheel contacts the ground and where the steering axis intersects the ground.
The calculator uses the simplified trail formula:
Where:
Explanation: This simplified formula provides a basic estimation of trail, though more comprehensive calculations may include head tube angle and fork offset.
Details: Trail measurement helps determine bike handling characteristics. More trail generally provides more stable steering at high speeds, while less trail offers quicker, more responsive handling.
Tips: Enter wheelbase and chainstay measurements in millimeters. Both values must be positive numbers, and wheelbase must be greater than chainstay length.
Q1: What is a typical trail measurement for mountain bikes?
A: Trail measurements typically range from 90-120mm for modern mountain bikes, varying by bike type and intended use.
Q2: How does trail affect bike handling?
A: More trail increases stability at speed and in straight lines, while less trail makes the bike feel more agile and responsive in tight corners.
Q3: Is this simplified formula accurate for all bikes?
A: This formula provides a basic estimation. For precise trail calculations, head tube angle and fork offset should also be considered.
Q4: How does wheelbase affect trail?
A: Longer wheelbase generally increases trail, contributing to more stable handling, while shorter wheelbase decreases trail for quicker handling.
Q5: Can I use this calculator for road bikes?
A: While the formula works, road bike geometry typically uses different measurements and considerations for trail calculation.
