PSA Microshift thumbshifter/bar end shifters can change speeds without buying new shi
After various interactions with bikey people, I realized that many people do not realize one advantage to Microshift thumbshifters and bar end shifters is their ability to switch gearing via a simple index plate swap. Since shifters are pricey, one can save a lot of money when updating drivetrain parts.
There are two basic patterns for these shifters,easily distinguishable by the barrel size- small diameter and large diameter. The small diameter does 8,9, 10, 10 Tiagra 4700, and 11 road indexing. The large diameter does 10,11, and 12 MTB.
The index plate on all of these are replaceable, meaning that if one has the 9sp and wishes to index 8, one just has to acquire and swap out the index plate. This is one way to get 8sp indexing (not offered), by buying a 9sp and swapping out the index plate. For 7sp, one can use 8 and have one empty click.

Campagnolo synchros had a similar setup back in the day where
you could change out the rachet ring to get 6,7,8 speed variations.
Good on microshift for this setup.

This is good to know, thanks! I've got their 11 spd mountain bar end paired up with an SLX rear der and love it. I actually bought the set and put the front shifter on my daughter's bike. She has trouble shifting with the stock 105 R7000 front shifter (tiny hands).

No, Syncros were down tube mounted levers. Usually on braze on lever bosses. They were Campy's initial response to the Big S's SIS levers, late 1980s IIRC. Syncros were known to not index well. But as the rest of their drivetrains were not yet indexed optimized and most were from pre indexing designs that was no surprise. Andy

Now?
it would work perfectly, since there's only a few standards to work with, and they're actually internally consistent. Microshift could offer the appropriate inserts and have their stuff index perfectly with every combination of parts made since the mid 1990s. You could even have spares on hand, in case the only rear wheel you could find was SRAM, and you have a Shimano rear derailleur and Campy shifters.

Campy really had a great idea with Syncro. Match the lever insert to the rear derailleur and freewheel, and it was supposed to index. Didn't work then, because of too many variations in parts specs.

I will be reaching out to Microshift to propose this. I expect a positive response in short order.
