This is a late 80s Ritchey. Originally I thought it was an ascent but the head tube has these additional ornate features to it that make me think it is something else, likely an Ulktra from what folks have noted but also still never seen the head tube work that this one has on an ultra. Regardless, gorgeous bike. Ubrake/Roller cam rear and pretty much all m730/732. The shifter/lever combo should be swapped out as they are not correct on it. Sits as I got it from a seller whose collection I bought. I would keep it because it is in fantastic condition but it is too small for me so it needs to go to someone who can use it.
