EC44 Upper ZS56 Lower Geoshift 2 Degree Performance Angle Headset Short

GeoShift headsets may have a taller stack height compared to traditional headsets. The only drawback to using an EC upper bearing cup instead of a ZS bearing cup is added stack height. If you have at least 10mm of spacers, which is most often the case, you will simply need to remove 10mm from your spacer stack.
