🍀ORIGINAL 1978-1983 “SEAT POST CLAMP” MONGOOSE MOTOMAG BMX OLDSCHOOL SUPERGOOSE
I believe this seat clamp is a 1980 but it was made from 1976-1982. It is new. All parts are in great shape. There is no markings or manufacture stamp. Seat clamp has the square hole that the square shaft on the bolt matches up to.
