My rear index shifter has worn out after 30 years. Can someone help with the replacement I need? I have a 6 speed regina freewheel, 13/26, Will a synchro 2 shifter work? and what color is the index part, I think its the white one? Any help would be greatly appreciated. tom

I would think a Syncro II shifter would work, especially as it was supposed to be an improvement on the first version. Just make sure you have the correct indexing insert in the lever pivot body for the number of speeds on your FW, as the indexing spacing is different for each of the inserts. There's a table floating around the forum posts that will guide you on that. Just do a search.
The Syncro I shifters can actually work very well as long as you have the correct combination of chain and FW, and adjust your cables properly to get rid of any stretch and slack in the system.

Syncro 2 is appropriate. Here's a link to the insert you'll need. You may not need to replace the whole shifter. Maybe just sharpen up the indentations on your current insert or a g-spring needs replacing.

Use Syncro III shifters they have a third spring, and are better.

You find them hidden on bar ends of 9sp/10sp Time Trial shifters.

Match the 6sp index ring (color) you need based on the old chain/freewheel/shifter charts:

Thanks guys for the references.
Learned something useful today.

Now where's the best source for adjusting Delta brakes from the CdA era???

How well do you think an index gear made for a two spring shifter is going to work in a three spring shifter?

Syncro III was also available in a downtube configuration.

Well,......First thing you should get is a 3.5mm allen wrench ( for the internal cable pinch grub screws.), a good brake cable cutter that can get into tight spaces and maybe a third hand tool..... and a lot of patience....
Just installed Deltas on my Pinarello Montello a few weeks ago and they are the fussiest brakeset I ever installed on a bike (didn't help that the Pinarello routes its rear brake cable through the top tube.), and it's not just the calipers, the first gen Aero/non-aero capable levers had their own complications.
Somebody must have done a how to video on how to install these brakesets. I have not found them but you really can just figure it out yourself if you go through the install slowly and very carefully.......
Here's a few tips I can share :
Do not cut the cables till you get the calipers totally adjusted and ready to go, as you pretty much only have one shot of cutting the cables to final length as they cannot protrude more than something like a millimeter and a half or two, past the internal cable clamp.
It would also be good if you replace the brake pads with new ones, as Campy delta type brakes supposedly tend to lose quite a bit of its performance as the pads wear out. Adjust the brakes so the pads are in good, firm contact with the rim sidewalls with the cable adjuster on top of the calipers screwed out as much as possible, then you can just screw down the cable adjuster to establish final clearance between the rim and the pads once you get proper pad/rim spacing good, then, and only then you can cut the cable very close enough to the cable pinch screw so the cable end does not stick out of the caliper housing and mess with your tires below it.

All Syncro shifters use the same index gears, as I understand it. The third spring just improves shifting and gear retention.
