What options are there to change the saddle mount on an aero seatpost of an Stevens Arcalis 2017 to mount a saddle with non-round carbon rails?
Below you can see the saddle mount that is designed to accept round saddle rails only. Usually 6mm x 6mm or 7mm by 7mm.
Are there any options – specific to this bike or general purpose – to allow that?
Stevens Vertriebs GmbH (firstname.lastname@example.org) informed me via email
... we are sorry, we don´t have Arcalis saddle clamps for Carbon-Rail available
So stevens does not provide any replacement part for my purpose.
