Geometry by size

Alterra CF1 standard Low geometry. Raw HTML row headers resolve the shifted simplified table. Manufacturer labels seat-tube length Effective; unspecified seat-angle convention is not silently mapped to effective seat angle.

Select a size heading or any value in its column to update the configuration and size-specific details.

Bike geometry illustrated

The redrawn reference shows markers A–O. Focus or point to a measurement in the legend to highlight its marker.

This redraw illustrates measurement locations, not the selected bike's frame or proportions. The values alongside are documented for the selected size. Unavailable measurements remain undocumented. Fork length is not suspension travel.

Live size comparison

Change the selected size here or above to update the overlay and values. The reference size stays fixed until you change it.

Reference: M (faded)Selected: L (full opacity)

Size L overlaid on size MBoth layers use the same transparent reference artwork, aligned at the bottom bracket. Each is scaled horizontally by its published reach and vertically by its stack. This illustrates reach and stack differences only: wheelbase, angles, wheels and frame shapes are not reconstructed. Use the documented values and deltas below for all other measurements. This is not a fit prediction.
