Baseline Sizing · 7/31/2026
Saddle Height
LeMond method (inseam 84cm × 0.883) yields ~742mm; this range accounts for cleat/shoe stack and pedaling style variation.
Stem Length
Your Cannondale SuperSix EVO 1 is already fitted with 120mm; without torso/arm measurements, retain this proven baseline or try +5–10mm if you prefer slightly more upright positioning.
Crank Length
Your current 172.5mm is well-centered for an 84cm inseam; no change needed unless you experience knee discomfort or feel constrained in the pedal circle.
Saddle Setback
Femur length unavailable; start near the middle of this range and adjust forward/backward by ~10mm if knee position over the pedal feels off.
Bar Width
Your current 420mm matches shoulder anatomy reasonably for a 185cm male; widen by 10–20mm only if shoulders feel pinched or stability suffers in sprints.
Bar Reach (Horizontal)
Reach of 395mm on your SuperSix EVO 1 is your proven fit; without torso/arm data, keep this value and fine-tune saddle setback if needed rather than changing stem length.
This is an estimated baseline derived from your inseam and the known geometry of your Cannondale SuperSix EVO 1, not a substitute for a professional fit. Your current bike setup (120mm stem, 420mm bars, 172.5mm cranks, 395mm reach) serves as a solid reference point; the saddle height estimate of 740–745mm aligns with the LeMond formula and should be validated on the bike before making other changes. Without torso and arm length, precise reach and stem recommendations remain uncertain, so treat the stem length and reach ranges as a starting point to confirm by feel. Small iterative adjustments—particularly to saddle setback and bar width—will likely yield more comfort than wholesale changes.
