I've been thinking about putting a Suntour Ultra 6 freewheel
on my wife's Eisentraut. I figure this might be a good way
to get an extra gear without having to coldset a 28 year
Question is, I can find the Freewheels, but not the ULTRA6
chains. Does anyone know of a contemporary chain that
will work with the ultra design (which had smaller spacers
(and cogs?) to allow 6 speeds in 120mm frame spread)?
Thanks in advance,
