SRAM Rival 10 upgrade to 11 speed: what is the minimum

[sowestport]

Folks,

I have confirmed that the RD from 10 speed will work fine with 11 speed. I can imagine that the FD will work as well; although, I will not have the yaw benefit and I will probably upgrade the FD soon since it doesn't cost that much. Despite what SRAM says about the crankset chainring spacings, it seems that the crankset is the same if you believe FSA N10/N11 specifications.

So it seems the minimum upgrade path to 11 speed will be:

1. Shifters
2. Chain
3. Cassette - assuming you have a free hub body that will accommodate the extra 1.8mm width of the cassette.

Would like some feedback whether this is true. I need to figure out what the real budget will be for this upgrade.
