Biopace on a stock 80's High Plains?
the highplains pictured above has a crank which at least looks similar to the engineering marvel known as biopace.
You know, you are right. I remember the same silver crank/black chainwheel with the orange biopace sticker now that I actually look at the photo again. I never knew they used that on a highplains build.
thos cranks appeared on many bikes back in the day. They were pretty popular, but as we sometimes find out, the GOP isn't always the best solution, and eventually people learned how to pedal in circles properly.
that sounds badass, we found a mint set in our shop, before we decided what to do with it some old guy standing in the store offered us $50 for it. Apparently he was building up some bike for nostalgic purposes.
