Sram user manuals...WTF
I am installing my new SRAM Red cranks, which came with this...
https://sram-cdn-pull-zone-gsdesign....ranksets_1.pdf
I have the BB30 1-A model, which I guess is different from BB30 in that it uses an integrated preload adjuster rather than a wavy washer (which isnt explained anywhere). Why, on the digram, there is a green box around the spindle indicating I should measure the spindle, or why the diagram depicts a spacer that I shouldn't use, or what specific spacers I should use and where are among the issues not clearly explained. I was getting confused, but then I found this XX1 crankset service manual..

I dont have xx1 cranks, don't even know what they are, but its an entire manual explaining service and installation with clear pictures and actual words. Looking at the instructions for installing BB30 cranks (pg 37) it seems identical, except for the inclusion of the fat spacer I am not supposed to use with my Red cranks, near as I can tell, to the confusing diagram that came with my cranks. Why was SRAM so thoughtful to XX1 users to provide such lovely detailed instructions, and so mean to the rest of us in providing incomprehensible diagrams?

Yeah, Sram manuals are a mess. I also like that they print their manuals on the head of a pin.

I agree with your assessment. I've never understood what step 4, marked as "wide axle" and the 2 I guess spacers is supposed to be telling me? I think the IA version of the crank is aftermarket only. At least I've never seen the one with just a wavy washer offered for sale new (just take-offs). What that "manual" doesn't tell you is that Force 22 spindle is longer, so that it can be used on Cervelo "BBRight" as well as 68mm BB shells (Force 22 needs that spacer when used on a 68mm shell). XX1 I think was designed for 73mm shell, but can be used on a 68mm with spacers.
I also don't understand why on the Red 22 BB30 IA cranks the spindle is part of the NDS crank, but the Force 20 it is part of the DS.
