Body & Bike Data
Enter your body measurements and current bike setup, then save to open the Single-Bike Sandbox.
TT requires manual saddle measurements for each bike. Enter measured saddle height and setback in that bike's TT Saddle Position section, with its current crank length and seatpost setting. Inseam cannot supply a TT saddle height.
Reference Frame & Cockpit
Bottom bracket centre to saddle top, as set by the seatpost. One value shared with the rider bar, Method A and Method B.
TT Saddle Position — Manual Measurements
Mark one reference point on the saddle top. Measure height from the bottom bracket (BB) centre to that point, and horizontal setback to the same point, with the current crank length and seatpost setting. Re-enter height after a crank change and setback after a seatpost change. No automatic saddle estimate is used.
Horizontal measurement: positive is behind BB; negative is forward. Include the fitted seatpost and saddle rail position in this measurement.
Optional horizontal offset from the measured saddle reference to your pelvic contact point: positive forward, negative back; 0 uses the reference point. Do not repeat the seatpost setback here.
Enter manual measurements to resolve saddle X/Y, saddle-to-pad drop and reach.
These controls adjust parts relative to the selected stem and basebar. They are local hardware travel, not frame reach/stack limits. Changing frame size or stem moves the total pad coordinates shown in Live Telemetry.
Enter frame and stem geometry to see the BB coordinates covered by this local travel.
Measured vertical height from the stem's bar-clamp centre to the armrest mount base, excluding adjustable risers and pad foam. The mount sits on top of the bar, so the minimum is 16 mm. Verify the frame-specific cockpit mounts, permitted risers/offsets and clearances with the manufacturer before assembly.
Extra height above the fixed mount. Mount height and pad foam are added separately to Total Pad Stack.
Pad centre offset from its mount. Negative moves back; positive moves forward.
Horizontal distance from the stem's bar-clamp centre to the armrest mount. Stem length is adjusted separately.
