Contour Max Adapter
Contour Max Adapter · black
for seat posts Ø 25-32mm up to 3 kg max. load
The Contour Max adapter allows using larger and heavier bags than the standard Contour adapter on all seat posts Ø 25-32mm. Combined with a twin aluminum frame, the Contour Max adapter can support up to 3kg. Contour Max bags are larger than their Contour counterparts and provide plenty of protection against dirt and splash water.
We don‘t advise the use on carbon- or other lightweight-seatposts or recommend to take advice from the manufacturer.
