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: €3,199 at BIKE24.

Your size
What BIKE24 lists, and what it has today
This brand publishes no centimetre equivalence we can verify, so the bike appears only when you pick a letter size.
Where to buy
The same bike at 2 shops, matched on brand, model, drivetrain and model year
Our pick is the cheapest shop that actually has your size, not the lowest headline price.
