Hi,

I have a 2011 Scalpel with the BB30 bottom bracket. The bike currently has FSA Afterburner cranks, but I want to install the Cannondale Hollowgram SL XX 2X10 cranks.

Which spindle is the one to use for my bike?

Cannondale Hollowgram BB30 122mm Mountain Spindle - QC071

- or -

Cannondale Hollowgram BB30 132mm Mountain Spindle - QC070

I'm assume either will work and it's just a matter of how wide I want my feet positioned? Just thought I'd ask before plunking down a lot of frog skins just to lighted my bike.
