Hi there.

My sister who lives 400+ plus kilometres from me wants me to overhaul
and upgrade her old NORCO Fiori bicycle. It is a 10 gear setup. She
wants to go to 21 gears because ofthe hills she is encountering and
also to reduce the jumps between gears.

I have everything I need to convert this bicycle to 21 gears for her.
I can't remember if the distance between the rear dropouts is the same
for a 7 gear Shimano 600 hub and a regular 5 gear hub. Is it the same
distance for both a 5 gear and a 7 gear hub?

Thanks and cheers from Peter
