Hello, I'm looking to upgrade all my drivetrain parts and am thinking of going with a 8x3 setup. I'm looking at the following SRAM parts: -PG850 8 speed rear cassette -S600 chainset (I believe that's the correct word, I mean the gears that are by the pedals) -x4 shifters, obviously 8 and 3 speed ones -X4 rear derailleur 7/8 speed And this is where I'm stuck, the front derailleur. First of all, is all this compatible so far, second, what front derailleur should I get, cheapest possible SRAM one that would work with this setup please. Possibly X9 9 Speed? I have no clue. Any help is appreciated and please forgive my ignorance haha! Thank you!
