I'm so happy I found this thread! I have a new/old Norco bike, and I'm trying to find some info on it simply out of curiosity. Many of the bits and pieces have likely changed, it would be safest to say that only the frame is original. If anyone has one like this, I'd love to see images of the original bits, as I'd like to see if I could restore it to "original".

From one of the first posts, I gather that it was made pre-1975 as the serial number starts with SL. I was trying to find a model name, but I'm having no luck. Here are some images. I love this bike! This is the first time that I can pick up my bike with one hand nearly effortlessly! I've never been so excited to ride!
