I repair cars for a living, so I'm fairly handy with tools and mechanical things. After years and years with Shimano 3x7 and 2x8 groupsets, my new favorite bike (a pristine Surly Wednesday) came with a 12spd SRAM SX rear derailleur. Even worse 😁 it was so far out of adjustment that it only worked in 4, or 5 speeds maybe.

I've only recently learned to adjust derailleurs and I'm okay with old Shimano stuff. But this SRAM thing. Goodness! I finally dialed it in after 3 hours. At one point, I was fairly certain I broke the shifter, but it's fine.

I know I'm new to 12 speed, but is it really that much harder to dial in? Totally worth it, now that I've had a few rides. But damn.

Anyone have to adjust SRAM parts regularly? Any horror stories?

I watched some videos later which reinforced what I had learned the hard way; the B screw setting is critical for SRAM. There's a template, even. I don't think the B screw setting matters much to my old 7 and 8sp Shimano derailleurs.
