Wind Tunnel Report
Saddle height uses the LeMond formula: inseam × 0.883 (BB to saddle top). Frame size is estimated from inseam × 0.65. Reach is the horizontal distance from saddle to handlebars; Drop is the vertical difference between saddle and bars. Handlebar drop varies: relaxed (2–5 cm) vs aggressive (8–12 cm). The blueprint shows a fixed reference for your fit measurements.
