So my Synapse has a somewhat aero seat tube and my light has a round attachment. Seat says are also not round. I know there are lights out there with a more rubber band type attachment that would work, but I'd rather not spend money on another light. Anyone rigged something up for a situation like this that worked? I thought about rubber banding the original mount on but it has an L-shaped bracket that interferes.
EDIT: This kind of shows the mount
