Park Tool FR-1.3

Used to remove the Threaded Inset in the Chris King Micro Spline driveshell. We large made-in-house bearings to provide the most efficient and long lasting parts possible. In order to use our large and efficient bearings with the smaller Micro Spline lock ring we use a threaded insert.

When deciding which tool interface to use we chose the Park Tool FR-1.3 because it is a deep enough socket to clear the through axle and narrow enough a spline patter fit within the Shimano lock ring threads.

12 splines, 22.6mm diameter fits Shimano®, Sachs® Aris, Sun Race®, DNP® Epoch and other 5–10 speed freewheels. The FR-1.3 includes an enlarged thru-hole to accommodate 14mm axles. Base of tool can be installed in a vise or used with a 1" socket or wrench.
