Hey,
I'm looking for a combination of RD and FD, which I could use with an STI.
The RD/FD could be XT or SLX, while the STI I was thinking about something in the 105-Class.
The FD would have to be Low Clamp
Is there anything that could be working? I'd be cool with either 2x10 or 2x11.
I could imagine getting SRAM components, however I'm more used to the Shimano shifting.
Cheers

Hi,
Shimano old style 10-speed road STIs will work OK with 9-speed (and fewer) MTB RDs and FDS. That is: 5600 and 5700 105 series, and 6600 and 6700 Ultegra series.
10 and 11-speed MTB RDs are not compatible.
New Road Tiagra 10-speed STIs won't work. Neither will the 11-speed road STIs. They will work poorly both with the RD and with the FD (different cable pulls).
Note that 5700 and 6700 use under the bar tape cable routing, which makes shifting a bit problematic - the old 10-speed Shimano road shifters pull very little cable per gear shift compared to either 9-speed or the new 10 and 11-speed shifters.
So, for good shifting, and good ergonomics (at least for my hands and in my experience), I would opt for the 8-speed Shimano Claris STIs. They work surprisingly good.
According to Damir's feedback in the thread "
Sora R3000 sa XTR M971" (in Serbocroatian), the 9-speed Sora doesn't work very well with Shimano MTB RDs, so he ended up buying a 9-speed Sora road RD (my experience is over a decade old but I would say it worked OK - or at least good-enough, though it's definitely not "officially supported" by Shimano).
The 10-speed stuff is a lot more sensitive to any imperfections, so I would not expect perfect results (I wasn't very happy with the full 105 5700 group shifting quality).
