Sprockets mbili moja zimeundwa kuendesha minyororo miwili ya roller ya aina moja, hapa ndipo jina la "double single" lilipotoka. Kawaida hizi sprockets ni Mtindo lakini zote mbili za taper bushed na mtindo wa QD unapatikana ukitolewa kama ombi la wateja. Sproketi zetu mbili za moja zimetengenezwa kwa meno magumu na zina rangi ya asili au mipako nyeusi ya oksidi kwa utendakazi bora na upinzani mdogo wa kutu. Saizi za hisa za sprockets moja mara mbili huanzia ANSI #40 - #80/DIN06B-16B lakini saizi za ziada zinaweza kutengenezwa baada ya ombi. Jambo muhimu kukumbuka ni kwamba ingawa sprockets hizi ni sprockets mbili hazitakuwa na mnyororo wa roller mbili.
