Dûbele toanhichte kettingkettingkettingen binne faaks ideaal foar romtebesparring en hawwe in langer wear libben dan standert kettingwielen. Geskikt foar lange toanhichte ketting, dûbele toanhichte tandwielen besitte mear tosken dan in standert tandwiel fan deselde toanhichte sirkel diameter en fersprieden slijtage evenredich oer de tosken. As jo transportketting kompatibel is, binne kettingwielen mei dûbele pitch perfoarst it wurdich te beskôgjen.
Sprockets foar dûbele pitch roller keatlingen binne beskikber yn in inkele of dûbele toothed design. Single-toothed kettingwielen foar dûbele pitch roller keatlingen hawwe itselde gedrach as standert kettingwielen foar roller keatlingen neffens DIN 8187 (ISO 606). Troch de gruttere kettingpitch fan dûbele pitch-rolkettingen is it mooglik om duorsumens te fergrutsjen troch tandmodifikaasjes.
Standert roller type sprockets binne deselde bûten diameter en breedte as de single-pitch ekwivalint krekt mei in oare tosk profyl te tastean goede sitplakken fan de keatling. Op sels tosken tellen dizze kettingwielen allinich mei de ketting op elke oare tosk, om't d'r twa tosken per steek binne. By ûneven tosken wurdt elke opjûne tosk allinich ynskeakele op elke oare revolúsje, wat fansels it libben fan it kettingwiel fergruttet.
