I am slowly making progress and getting together the final components of my MTB super-bike (will post pics when done).

Last thing I need is a Cannondale BB30 bottom bracket spindle.

Here are the stats:

Frame: Cannondale F29 Carbon 29'er with BB30 press-fit bottom bracket bearings
Crank: Cannondale Hollowgram SiSl 175mm with Sram XX1 compatible 4 bolt single spider

From what I am seeing online the choice is looking like the Cannondale Hollowgram BB30 132mm Mountain Spindle - QC070. I have been hearing rumors that there may also be a 131mm spindle out there.

Interested to get a recommendation on if the QC070 is the correct spindle and the correct number of spacers and wave washers required. Thank you in advance.
