Werfen wir erneut einen Blick aufdie Ritzel und Spacer des gewöhnlichen "Perfect" Fünf-Gang-Freilaufs. Wegen der unterschiedlichen Abstände und Zahl der Ritzel, gab es die "Perfect" und "Pro Compe" Schraubkranzfreiläufe in verschiedenen Ausführungen von Keilverzahnungen, Gewinden und Breiten. Spacer unterschiedlicher Stärke stellen die unterschiedlichen Ritzelabstände her. | |||
Der Spacer hinter dem äußeren 15-Zähneritzel ist angeschrägt, um einen Kontakt mit der Kette zu vermeiden. | |||

The two leftmost spacers, between the splined sprockets, are 3.5mm thick and the sprockets are 2mm thick, for a combined spacing of 5.5mm. The outer spacers are only 1.9mm thick because the outer, threaded sprockets are thickened near the center hole for the threads. 14-tooth threaded sprockets and 16-tooth splined sprockets have integral full-width spacers. Splined sprockets with 17 or more teeth are flat and use separate spacers, as shown. Ultra spacing uses thinner spacers. The table below identifies the different spacers. | The two leftmost spacers, between the splined sprockets, are 3.5mm thick and the sprockets are 2mm thick, for a combined spacing of 5.5mm.

The next photo shows a Perfect body with three splined sprockets and two spacers in place. The red arrow points to one of the splines. The rightmost splined sprocket overhangs the larger-diameter section of the freewheel body, as shown, so that the spacer behind the next, threaded sprocket can secure the splined sprockets. | The next photo shows a Perfect body with three splined sprockets and two spacers in place.
