I took some measurements of the bike last night. It's a whopping 13" distance from the lower eyelets to the seatstay eyelets and only 6.25" drop! A highly unusual rear triangle. I've been in contact with OMM and they proposed either clamps (d-rings?) to substitute for the seatstay eyelets or longer extenders for the rack. I measured the seat stays and they are 1.25" wide and a diameter of 3.75". Beefy. I'm also concerned about the integrity of very long extenders. I really hope something works...
