THIS IS A SET OF FRONT AND REAR VINTAGE BLUE BRAKE CABLES SET TO FIT A LOT OF BMX BIKES. THE FRONT CABLE IS 41" INCH LONG AND THE REAR IS 47" INCH LONG. THEY ARE EXACT MATCH FOR THE 1986 AND 1987 GT PRO PERFORMER AND STANDARD GT PERFORMER. THE FRONT CABLE IS LONG ENOUGH TO GO THROUGH THE STEM BOLT AND THEN THROUGH THE FORK TUBE AND WRAP BACK UP TO THE CALIPER. THEY WILL FITS INTO MANY OTHER BMX BIKES LIKE REDLINE, RL20, HARO MASTER, FST, DYNO & OTHERS. THERE IS NOTHING STAMPED ON THE CABLES BUT IT IS A RARE HARD TO COMEBY OLD SCHOOL VINTAGE BLUE CABLES THAT YOU CAN'T BUY IN NORMAL HARDWARE STORE ANYMORE.
