Park Tool Freewheel Remover (FR-4)

I was worried about finding the right tool for my old SunTour freewheel, but this spline remover fit perfectly and didn't slip at all. The machined finish on the tool steel feels really precise in hand.

The heat-treated tool steel construction feels incredibly solid in my hand, and it engaged perfectly with the splines on my vintage SunTour freewheel without slipping at all. I was worried about damaging the old part, but this made the removal smooth and easy.

Finally got this for my old SunTour freewheel and it clicked in perfectly with zero play. The heat-treated steel feels solid in the hand, and it didn't slip even on a stubborn unit that'd been sitting for years. Exactly what I needed for that vintage build.
