Knee Pain From Cycling? Check Your Saddle Height First
What anterior vs posterior knee pain points to, the three-tier BDC knee angle ranges (140–150° / 135–145° / 130–133°), the limits of the LeMond formula, and safe ±3mm adjustment steps.
How to Set Saddle Height: 4 Methods Compared
Heel method, Hamley 109%, LeMond 0.883 and the BDC knee-angle method — principles, accuracy, error sources, and the "formula as start, knee angle as calibration" workflow.
What Torso Angle for TT / Aero Position?
Elite TT 4–12°, national elite 8–18°, road aggressive 30–40°; the ~14% power cost of going flat (24°→0°), the hip-angle constraint, and progressive lowering.
AI Bike Fitting vs In-Person Fitting: How to Choose
An honest capability-boundary table: what video fitting can do (±3° angles, directions, cheap re-checks) and what it can't (cleats, insoles, palpation, pain management).
