I cannot get the little catalog pix enlarged and sharp enough to be sure, but seems like the Top Cross Trekking model does have the seat cluster with cables for both derailleurs (and FD passing thru the seat lug) plus the rear brake bridge...unless you tell me I'm wrong I will amend the notes for Masciarelli to name that model
Would the Top Cross Trekking need different (from the ones on the red frame above) top tube cable guides that accommodate all 3 cables?
