backrest support including customised
backrest upholstery. The adjustment
possibilities of the
adjustable backrest

The
Overlite frame version
has a special
version of the Ergo Back backrest bracket. In
this case, there is no adjustable backrest
support under the backrest upholstery, rather a
backrest support
which is fixed to the frame
tubes
using Velcro tapes
. There are no
possible adjustments here.
