I cant find a serial number anywhere on this schwinn does anyone have an idea what year? This ones gonna have the sickbikeparts shifter kit,nuvinci rear hub (currently getting spokes made and laced) at bike shop, a buddy of mine gave me this frame and it was wide enough to use the nuvinci hub. Putting hydraulic disc brake on rear also when i get the hub back.Thanks to anyone that can tell me something about the frame. Also i cut the original kickstand bracket off since the kickstand was gone anyway and i liked this one better
