finally I became a member to be able to post a reply here.  That's my bike and it is pretty lovely!!  The frame is made of aluminium, wheelbase is 1000mm (available also in 1020mm), cs 350, bb +70, head angle 71.5° and weight 1590g!!  I enjoyed riding this bike a lot but finally I came back to my old DOB full disc frame which is more comfortable for my old school riding
