My 78' Grand Prix doesn't shift that well, specifically from the smallest cog it wants to skip to the 3rd cog on a 5 speed original freewheel. And getting it into the very big 34 tooth first cog is anything but smooth.

Reading on the Harris site about modern chains & teeth with ramps, etc. I'm wondering how much improvement I'd feel with a modern freewheel and new chain. If it's not going to improve smoother shifting I guess it's not worth the hassle?

My real question since I'm still new to this addiction is if there's a true design difference in today's minute gear and tooth patterns (and chains) vs. what's on this bike from 31 years ago?

Thanks in advance.
