The real deal vintage used old school MKS Diamond Back 9/16 pedals in anodized blue for your Diamond back rebuild. These are used and off of a 1983 Diamond Back Viper I recently obtained with a lot of bikes. Also have the bars and FF up for sale soon. Not a big Diamond Back fan. The pedals have wear all over from being used but no major damage, some bending at the ends from being laid down on. Spindles spin freely but will need regreased and end caps are missing. Have the Diamond back name on the ends of the pedals. A great usable part for Diamond Back rebuild or get them redone for a museum bike. 

Item sold as is and any questions please email me.
