Baseline Sizing · 7/29/2026
Saddle Height
Inseam × 0.883 suggests ~74 cm; your Trek Domane is at 780 mm, which is above this baseline estimate—likely dialed for your specific cleat stack and pedal style, so treat 742 mm as a starting point if moving to a different bike.
Stem Length
Your Trek uses 110 mm; without measured torso and arm lengths, a 5–10 mm range accounts for fit variation across bikes of similar geometry.
Crank Length
Your Trek's 172.5 mm crank is a standard length for riders near your inseam; no change needed unless you notice cadence or comfort issues.
Saddle Setback
Your Trek is set at 65 mm; without femur length, this is a reasonable range to explore if knee position feels off over the pedals.
Bar Width
Your Trek uses 42 cm; shoulder width would refine this further, but 42–44 cm is typical for female riders in the 185 cm range.
Your Trek Domane SL 6 provides a solid reference point. Since you've supplied only height and inseam, the baseline saddle height of ~742 mm is an estimate; your current 780 mm likely reflects your actual cleat stack and feel. Reach (stem length and bar position) is hardest to estimate without torso and arm lengths—your current 110 mm stem and 600 mm stack on the Trek are good anchors. This is a starting-point framework for a new bike or validation check; it is not a substitute for a professional fit, and your dialed setup on the Domane remains your best reference unless you report specific discomfort.
