Geometry by size

Geometry setup conditions are not fully documented. Do not assume these figures apply to other configurations.

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: S (faded)Selected: L (full opacity)

Size L overlaid on size SBoth 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.

At least one geometry setup is undocumented; direct comparability is uncertain.

Manufacturer height guide

180–195 cm

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

Price observations

No sourced price observation is recorded for this build.

Prices are in euros for the stated build, market and date. A conversion is an estimate, not a local retail price. Historical observations are not current offers. Confirm taxes, fees and final price with the seller.

Availability

Current stock and delivery availability are not verified. Check with the manufacturer.

Intended use and assessment

All-Mountain

No sourced strengths or trade-off assessment is recorded. Specifications alone do not establish how a bike will ride.
