What to do with downtube shifter bosses?
So thinking about putting a set of bar end shifters on a bike with DT shifter bosses, anyone have any good ideas about what can be done with the empty bosses? I'm hoping for pics

Uhh... Cable stops? That's what everyone else does to help them run the cables to the deraillers.

I have a new set of these cable stops I'm not going to use. PM me if interested.

Do you need to make fine adjustments like that with friction shifters?

you don't need to make fine adjustments (though you do want to have the cables start out tighter than they might with an indexed system), but you need something to end the cable housing / hold it in place / while the bare cable keeps on going to the derailleur.

And don't put those cheesy Shimano Dura Ace ones on there.... use Campy!
(unless you really want Dura Ace, in which case I have a billion bagged ones laying around here)

Actually you will probably need a clamp on style cable stop, and use the mounting block for the Symmetry shifters to keep the stop from sliding on the down tube. Find an allen bolt to fill the hole, to keep water out. Find an old cheap ten speed for the clamp on stop, or one of the guys here should have one.,,,,BD

You're done. No adjustment, but you've got the most unobtainable component in town. Congratulations.

My neighbor is part-owner of a large custom fab metal shop and I've been trying to get one his best machinists to come up with a blank but cool cover for the kitten killers among us so when you convert that beautiful old road bike to--eeeeeeek--fixie or ss you don't have to either leave the dt levers in place or ride around with the exposed bosses which are not aesthetically pleasing to look at; so far no luck, but I do think it's an idea that has some small merit.

I'll bet today's LED technology would lend itself to some sort of supplemental dual headlight system (or even turn signals -- remember those for bikes?) to mount on the shift lever bosses.

^ Indeed, someday we'll look back at the lost heritage of the road bike in a manner not unlike the Inca, whose treasures were melted down for coins, or lost at sea.

The problem is that they wouldn't spin. Two "true" propeller blades facing the wind will cancel themselves out. It would look cool though. The only drawback with grinding off a symmetry shifter mount is the 1/4" hole that will be left in the down tube.,,,,BD

Don't lose the bolt! It's special. Find a little block of aluminum and a drill press. Make two holes for the cables through the block, boring one side out larger for the housing. Make a hole for the bolt (recessed if possible). Spend a week on this.
You're done. No adjustment, but you've got the most unobtainable component in town. Congratulations.

[QUOTE=John E;8208280]Anything which saves a fine old frame for a potential geared rebuild when the silly ss fad dies its well-deserved death is a welcome concept. How about some sort of red LED blinkie to screw into an unused derailleur tab?QUOTE]
I'm way ahead of you.
I modified a Japanese bell so it screws into the single shifter boss on my Peugeot PA10.
