        "note": "Pitch diameter = pitch ÷ sin(180°/teeth) — the circle the chain pins ride on. The outside (tip) diameter is a touch larger, ≈ pitch × (0.6 + cot(180°/teeth)). More teeth runs smoother and quieter with less 'chordal' speed variation; keep the small sprocket to 17+ teeth where you can.",
