Bought an SLX crank 22/36 and plan on running a 2x9 since my current cranks are shot (3x9) and want to cut back on costs. Couple of q's?
1) Will I need a new 2 speed fd too?
2) Are the newer sram x9 or xo 3x9 shifters compatible for 2 speed or do I need specifically a 2 speed shifter for the front?

Thanks

Hmm, don't think you should have any problems running those components 2x9. I run a 3x10 SLX shifting set on a 2x10 set-up just fine. I just have to be careful not to grab for that big ring because I'll shift my chain off the chainring. One other suggestion I'd make would be to make that third ring a bash guard...really will save your chain ring!

When the xx1 1x11 came out I salivated. Then I saw the price and started thinking about other 1x options...

I'm running the same 22-36 slx cranks on my hei hei 29r. I finally took the bash ring off to save 5 or 6 oz. and make it look better too. I have had the chain come off the big chain ring a few times since then, but I adjusted the limit screws to stop that. Front shifter doesn't matter, use what you got.

Some front ders have an issue binding up if you run the outer limit screw down enough to prevent over-shifting. Essentially, the head of the screw gets in the way of the body of the cage, and doesn't permit it to move freely. I've seen it with X5/X7 level parts, but haven't tried adjusting X9/X0 or Shimano stuff up from a triple to a double.
