Sram XX Shifters 2X10 and 3X10 Compatable
If I buy a 29er with OEM 39-26 crankset and Sram XX shifters... then decide I still need smaller granny gear to spin up my long climbs, can I switch to a 3X10 crankset with same shifters, or will I need to replace the shifters as well?
If I don't like 39X26 I realize I could go 2X10 38-24 crank, but want to understand all options. I'm more familiar with Shimano shifters and understand I can use shimano shifters for 2X or 3X setup, and am assuming Sram is similar...
I think I answer my own question: Nope.

Your right, you can't do that.
However there a few aftermarket companies making a 24 tooth for the 80mm, so you can always go that right.
You might be surprised to find out you won't miss your 22 or 24. I thought I was going to miss it, but I never did. I have been to N.C. several times and never felt the need for a lower gear.
Hope this helps.
Oops....26t is the smallest for 80mm. I was thinking 74mm.
I was worried about having the extra climbing gear as well. Thus far, I haven't needed a smaller chainring on climbs I would normally need a 22 on (fingers crossed). These are average grades of ~10% for 1.5 miles.
