Bike Fit Measurements

Bike Fit keeps a record of your position on each bike: the numbers from a professional fit, or the ones you measured yourself. Each set of measurements is saved as a version, so after a saddle swap or a new fit you can see exactly what moved.

Opening Bike Fit

• On a bike's page, choose Bike Fit in the header, next to Race Day and Settings.
• On the Bikes list, choose the ruler button on a bike's card.

Bike Fit is for bikes you still ride, so it is hidden on retired bikes.

What you can record

Measurements are grouped into six categories. Fill in only what you have; every field is optional.

• Body Measurements: height, inseam, torso, arm and leg lengths, sit bone width.
• Frame Geometry: seat tube, effective top tube, stack, reach, head and seat tube angles and more.
• Component Specs: crank length, stem length and angle, handlebar width, drop, reach and rise, saddle width and length, spacer stack.
• Position Measurements: saddle height, setback, fore/aft and tilt, handlebar height, saddle-to-bar drop and reach, handlebar rotation.
• Cleat Position: fore/aft, medial/lateral, rotation, stance width.
• Biomechanical Angles: knee angle at the bottom and top of the stroke, hip, torso and elbow angles, KOPS.

Each measurement has a number and a short description of how it is taken. Lengths are entered in millimetres or centimetres and angles in degrees, whatever your distance units.

Versions

Every measurement set is a version with a date, an optional name such as "Pro fit — March 2026", and optional notes. The page shows the latest version first. You can:

• Switch to any earlier version.
• Compare two versions side by side, with changed values highlighted and the difference shown.
• Edit a version in place, or save your edits as a new version to keep the history.
• Delete a version.

Bike Fit is also available in the mobile app, under each bike's Setup section.
