I have a 10 year old Guru Sidero that I absolutely LOVE and just broke the hanger. I am trying to track down a replacement (I believe the Guru Praemio used the same hanger), but they used a very unusual one (see attached photo). Also trying to be creative and think whether there might be abandoned Guru's or cracked frames or some other way to source this piece from a discarded bike. Just desperate to not hang up this bike for good due to a $25 part
