I bought this bicycle second hand two years ago. The previous owner did not mention the model or year.
I messaged a Norco customer service representative. He couldn't pinpoint the model or year, but said it was probably from the early 90s.
The serial number of the frame is: Y9N3724
The wheels are not original.
