It's been a while since I've been on here and trolled through the various posts about gearing, but I seem to remember folks converting their 3x9 cranksets to 2x9. I thought (and could be way off) that they were installing a 38, 40, or 42 to the middle position and a 26 or 28 to the inside, replacing the granny ring. I tried this with a 28 and 42, but ran into issues with the larger 'ring contacting the chain stay. I don't feel comfortable adding another spacer to the drive-side bottom bracket cup as I've got 2 there already. Am I missing something? Is this setup even possible with my current frame/drivetrain?
Thoughts?
'08 Niner Air Nine (scandium)
'09 XT drivetrain (22, 32, 44 crankset (M770?))
My ultimate goal is to find a more-useable gearing for the type of riding I do. I don't necessarily want to drop my larger ring below 40-42.
