#GEOMETRY CALCULATOR ONLINE FULL#
The full history of edits is kept so you can undo until the starting point. Undo: undo the last measurement edit (or import).If there is no shadow bike already, a copy of the current is made. Swap Bikes: swap the main bike and the shadow bike.Shadow Bike: enable the shadow bike (an extra bike to compare with), which will show up as dashed chart.
Anchor: when the shadow bike is enabled choose which point to use as reference (that is where the bike should be aligned), default is the bottom bracket.Fixed top is the default and most practical while measuring a bike. Head Tube: choose if changes to head tube length should expand/shrink up (fixed bottom) or down (fixed top).Fork: choose if changes to fork should rotate the whole frame (as it would in reality), or if the head tube angle should be fixed (which is the default as it's generally more practical).Extra: a special button that toggles related extra measurements for the currently active measurements.Fit Delta: only enabled if the shadow bike is active, and then it shows the fit difference between the two bikes.Head tube angle and fork rake should also be reasonably similar. Assumes that bottom bracket drop and handlebar diameter is the same between compared bikes. Quick Fit: a few measurements to quickly compare the fit of two similar bikes.Bike Fit: measurements that are interesting in a bike fit context.Components: measurements related to the components added to the frame.Frame Geometry: measurements related to frame and fork.
#GEOMETRY CALCULATOR ONLINE HOW TO#
How to do this is described in the "measuring a bike" section. Measure: shows measurements to enter to make a complete measurement of an existing bike.Each button enables a set of measurements, and several can be combined although the chart can become a bit crowded. The measurement buttons are toggle buttons, red = off, green = on. On small screens you need to use page zoom. While the app works on small mobile phone screens, it's best experienced on a tablet or desktop.Have this help column visible while working to make it easy to follow the documented workflows for measuring a bike or copying a geometry chart.There are unlimited amount of undo steps. Use the Undo button for reverting edits (or imports).The current state is stored in the browser URL (link) so to share the chart just copy and share the URL.No measurements are shown for the shadow bike, but you can swap it to the front any time by pressing "Swap Bikes". Shadow bike: press the button to enable the shadow bike (=an extra bike) to make visual comparisons.Tap on the title to change name of the chart.When making a measurement or comparing, carefully note exactly where the measurement start and end in the chart (for example if it's the top, back or center of a tube).When editing, all other measurements will automatically adapt to match. Edit a measurement by tapping on its number.Toggle different sets of measurements by pressing the buttons on the top row.The app is made for recording and comparing bike fits and frame geometries, it's not designed to make bike fits based on body measurements (which is a bad idea anyway, as good bike fits are made using dynamic evaluations). Test how fit is affected by adjusting or changing components.Test size and fit of a frame before buying.Calculate a full chart from the often sparse geometry chart provided by the manufacturer.Calculate frame geometry of an existing bike through simple XY measurements.Use cases for this Bike Geometry Calculator web app:
