"Perfect for maintaining RS shock absorbers. But change the SPI gasket regularly".
"This adapter does not "fit" a Rockshox Monarch Rx shock absorber. When screwed into the shock body, it presses against the shell before sealing with the O-ring. It's necessary to ream the internal conduit larger. Before I understood the problem, I tinkered with it by removing 1.5 turns of thread; it's now difficult to use."
