Geometry by size

e-Siryon v2 geometry: F2 (Medium) and F3 (Large) only. Unrelated F1 values in the site's translation payload are excluded; bottom-bracket drop omitted because its sign convention is unclear.

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

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: F2 (faded)Selected: F3 (full opacity)

Size F3 overlaid on size F2Both 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.

Manufacturer height guide

No manufacturer height range is recorded for this size.

Height guidance is a starting point. Rider proportions, setup and preferences also matter; this is not a fit guarantee.
