Upgrade your Shimano rear derailleur with the GC 40 or GC 42 and experience smoother shifting and improved drivetrain life with our high-quality B-screw. The GC 40 requires a longer B-screw for optimal performance, while the GC 42 almost always needs one. However, when paired with our GoatLink, you can enhance your setup without the need for a longer B-screw. Ensure compatibility by checking the details on the GoatLink product page.
- Weight: 2.5g
