>>1386275 (Me)an update on this. i've found out that the cateye OH-2400 is pretty smol but you don't save weight because it's made of brass and especially elderly people struggle to hear it. cateye OH-1400 seems like an overall good bell and it has flexible mounting options so you can hide it to optimize your aero or you can just let it sit on top in order to not sacrifice acoustics or ergonomics. spurcycle/rockbros is a good option if you care more about the acoustics than i do.
