SA-RB
By applying a special anti-rust treatment to the bearing itself, the resistance to rust has been greatly improved. The SA-RB also has the sides sealed with an anti-rust material, significantly reducing salt buildup caused by salt recrystallization inside the bearing.

55mm long single handle + large EVA handle knob
The handle is longer than the previous model, at 55mm. In addition, the adoption of a large EVA handle knob has improved winding performance.
