I tend to find myself with the strangest of things. Bicycles and bicycle components are no exception.
I know nothing about these bars except they say Technomic on them, and I was told they were a custom project from Nitto. I have no idea on a year, model, or anything else really - they look like an early, early precursor to the legendary Nitto Tsubasa.
I might bring these to the bike expo here in November and see if anyone knows the backstory.
They remind me of a manta ray.
