I know, right? It’s an Ofmega Sierra crankset https://velobase.com/ViewComponent.aspx?id=6209f42f-cbef-4a2a-a2e7-8268a780b197 which AFAIK was supposed to be a triple but looks like Legnano stuck on an extra outer chain ring instead of a bash guard. On the rear is a bog standard Shimano 5 speed freewheel. Boom- 20 speeds!*
