🔧 The Pro Cassette Lockring Socket starts as a solid piece of alloy tool steel, fully machined to precise tolerances and optimally heat treated for maximum strength and longevity.
Designed with the professional mechanic in mind, it includes a fixed 5mm guide pin and a removable aluminum 12mm pin held magnetically for an easy, precision-fit "pop." Extra-deep splines provide superior engagement while quick-spin knurling delivers speed and control.
