84 Cannondale SM 500 26”front/24” rear. This is the first year Cannondale made a mountain bike. Most of the parts are original, paint was originally a blue/grey color but when I rebuilt the bike I painted it the 1985 yellow color. I have MANY hours into refurbishing the bike, it rides like new! Frame measures 18” center of bottom bracket to top of top tube, the picture shows it set up for me 5’8”.
