This is a front load stem. It is silver GT Mallet style with chrome bolts. This stem is for 1" threaded forks (21.1mm) and 7/8" bars. This stem is a 21.1mm which will fit most old school BMX bikes. This stem has a hollow "Potts" mod bolt and it has an integrated adjuster that work with ACS style rotors. Again, this stem is new production, it is not original old school GT.
