Rixen Kaul is a leading European producer of bicycle bags, and the Rixen Kaul’s KlickFix line of
bike bags are very much the product of German engineering and design.
All distributed products use the KlickFix System, where bags and baskets can interchangeably be
removed and replaced with others by way of an adaptor. Therefore, to use this product, you must
purchase either an adaptor or seat post extender adaptor.
