A set (2) of chain adjusters with caps for the Bevel Drive 900ss, 750ss and 750 Sport/GT Ducati Twins of the 70's and 80's. These chain adjusters fit in the swingarm tubes unlike the 860 GT/GTS and Darmahs where the Eccentric Chain Adjusters are in the frame. Newly Vapor Blasted and ready for use. I also have the bushes that work with this set-up as well.
