Another advance pioneered by Sun Tour was in freewheel removal. Sun Tour still stuck with the traditional two-prong remover design, but provided much deeper notches and a matching tool with a considerably better fit. The result was a much lower incidence of damaging tools or freewheels. | Another advance pioneered by Sun Tour was in freewheel removal.

Sun Tour also popularized the use of splined sprockets. Previously, the vast majority of freewheels used all threaded sprockets. Typically, the two largest would have left-hand threads and screw on from the back side of the body, while the smaller sprockets would screw on from the right. A freewheel would typically have 3 different threadings for sprockets in the different positions. The largest sprockets were the most difficult to unscrew, because they would get screwed on the tightest during hill climbing. | Sun Tour also popularized the use of splined sprockets.
