Contour adapter for seat posts with a diameter of 25-32 mm, maximum load of 2 kg. This compact, inconspicuous adapter can be mounted on all common seat posts, allowing for quick and secure attachment of a bag even on bicycles without a luggage rack. It comes complete with two stainless steel clamps, suitable for diameters of 25-28 mm and 28-32 mm. A clamp for oversized seat posts with a diameter of 32-36 mm is also available. Since the red button is mounted on the bag holder side, only a small, unobtrusive adapter piece remains on the saddle when riding without a bag. We generally advise against using it on carbon or other lightweight seat posts, or recommend consulting the manufacturer's advice. Dimensions: 0 cm x 0 cm x 0 cm, weight: 50 g, volume: 0 l, maximum load: 2 kg.
