Tiagra 4700 10 speed flat bar shift compatibility

[Tootyred]

Just a quick sanity check...

Modern stuff.....

Am I correct in thinking that tiagra 4700 10 speed flat bar shifters share the same pull ratio as 7/8/9 speed rear derailleurs in general and 10 speed road? I assume so, as are they not an option for flat bar bikes carrying road kit?

Or are they something completely else....like some durace?

If i could make any sense of shimano compatibility chart.....i would....but its basically incomprehensible to me!

Tiagra 4600 is backwards compatible with 789
4700 lever shares cable pull with 11 iirc, but the modern stuff is best well matched.

So 4600 10 speed is compatible with 789 derailleurs. Cool.

Does anybody have any experience of microshift sl t10 thumbies.

I tried some s.r. 9 speed ones ages ago and they were terrible! I assume the quality of the microshift is considerably better given the cost!

the later 10 speed cable pull will make the 10 feel better than the 9, but it's quite a lot to ask of a simple lever.

The Microsoft ones are early 10 road,so will be poor, due to short cable pull, and won't work with a 4700 mech, but v will with 4600.
Early 10 was worse than 9 due to less cable between gears.
Avoid.
