🛠 How the Tool Works

• Visualize front and rear gears (chainrings and cogs).
• Drag wheels or use the slider to adjust chainline and see chain behavior.
• Receive visual feedback (green/yellow/red) for safe, caution, or problematic alignment.
• Estimate correct chain length and detect potential issues like chain being too long or short.

🏁 How to Use It

1. Select Your Bike Type: Single-speed, MTB 1x, or Road 2x/3x.
2. Set Front and Rear Gears: Choose the number of chainrings and rear cogs.
3. Adjust Chainline: Use slider or drag wheels to modify alignment.
4. Observe Feedback: Check deviations and warnings.
5. Optimize: Adjust until the chainline is in the green zone.

🎯 Why Use This Tool

• Prevents premature drivetrain wear from misalignment.
• Improves pedaling efficiency and performance.
• Provides a visual, interactive understanding of chain dynamics.
• Useful for cyclists, enthusiasts, and bike mechanics.
