What is the difference between the RT-1 and the RT-2?
RT-2 is designed for the 1-1/4 inch and 1-1/2 inch headset standards.
RT-1 fits 1, 1-1/8 and 1-1/4 headsets.
*The RT-1 will also remove the PressFit 30 (PF30) bottom bracket units. The PressFit 30 inside diameter is the same as headset cups, and are pressed in the same manner.
