'6.2' .. Why not rebuild the rear wheel with a 3 speed internal gear hub?
reads like the wheel needs work anyhow..
yea, VT a double chainring with a front derailleur will work.
.. but you still need a chain tensioner on the back,
one with a spring loaded 2 pulley wrap up
Of that difference, between the big and small chainring..
Shimano has one for Alfine group... Paul's Comp makes one too, in the US.
or just use a RD, with the limit screws turned in to center it over that 1 cog.
Yes there are band clamp front downtube shifters, go right on..
If you have a 9/8" downtube..
Back in the day, the frames used them before the trend
was to braze on a fitting..
