HEDGEHOG STUDIO Daiwa Line Roller 1BB Tuning Kit SHG-RK (3pcs)

By adding a ball bearing (BB) to the line roller, you can tune it to have the same smoothness as the Tournament Z and other models.
This type of line roller cannot be configured with two BBs like the Exist.
The maximum number of BBs that can be installed in the line roller is one.
