[For SHIMANO] Line Roller 2BB Bearing Upgrade [Ver.1]

(Required Parts)
- Line roller BB (SHG-740ZZ or HRCB-740ZHi) x2
- Roller bush x2
- Roller washer A (0.2mm: thin type) x2
- Roller washer B (0.8mm: thick type) x2

This upgrade converts a standard 1BB line roller to the 2BB specification used on models such as the STELLA.
Smoother line roller rotation reduces line twist, which keeps the line supple and improves durability and casting distance.
