Where it stands

Priced below the market rate for its equipment, but another bike in its price range is priced further below it in the sizes where both are in stock. That is the only reason it is not the pick.

Where it stands across all sizes → The chart shows this bike at its cheapest buyable listing: €2,399 at BIKE24.
