I know this has been covered here but after trying it myself I felt like sharing this little trick again:

If you take a friction shifter supposed for a 2/3 front derailleur and install it upside down on the other side you get a cheap not indexed friction shifter for your rear derailleur. The front shifters aren’t indexed most of the time.
This specific one is a Sunrace SLM96. The rear one is indexed the front one not. It has many micro clicks but that counts as not indexed I guess.

It works like a charm with my DX derailleur and costs a fraction of the microshift thumbies. I also like the position way more that on top of the bar.

    I had this set-up on 7 speed and it was 2 clicks for all speeds except 4th, which was 1 click. But it bacame second nature in a few days and felt really reliable and gave a nice sense of connection with the deraileur. Also the shifter feels well made.

    TIL about Sunrace thumb shifters; love this sub. Thx for the post!

  3. Good call. I have the indexed SunRace M90 thumby on the right and it fucking sucks.

    i’m running that exact same one on my micro shift advent rear mech. It works pretty well but leaves a little bit to be desired. I just ordered the actual micro shift left side to put upside down on the right. The only issue I have is when I’m riding super aggressively I kinda have to let go with my right hand and sort of reach under the bars to drop from my biggest cog back down again. It’s a minor gripe but I’m hoping the actual micro shift one corrects that

    I’m running the same friction shifter on my 1992 rigid MTB and I like the shift experience even more than my “fancy” indexed 11 speed shifter on my new hardtail.

  6. I really wanted to get this one for my new Cues drivetrain. But apparently it might not have enough pull for a linkglide cassette/RD. Is true?
