ST. PAUL, Minn. (BRAIN) — Park Tool's new DW-2 is a wrench to adjust the clutch on Shimano Shadow Plus rear derailleurs, including recent XT, SLX, Deore, Saint and Zee models.
The DW-2 has 5.5 mm and 3 mmm openings to make the adjustment for riders who want to reduce the clutch tension for easier downshifting, or who want to tighten it.
