Hi gang --
We are adding another tandem to our stable: 1984 Santana Arriva.
It has a 5-speed rear cog and the triple looks like a 53/42/granny.
Being Clydesdales (370# team) we'll need to bring the drivetrain into the 21st century, or at least into our sunset years!
Does anyone have an idea how far we can go on the rear end before we're into a new wheel/hub? I don't yet know what the rear spacing is (we pick up the bike at noon today) so I'm just fishing -- wondering if anyone here is familiar with the vintage Arriva specs.
Thanks for any input -- I'll post more info as it becomes available.
Can you tell that we're excited?
