Or if you can find a 128 axel and remove the shoulder it'd only need a few small spacers extra.
If you look at Cannondale's install diagram for Hollowgram cranks
on a mountain bike with the SiSL spindle w/shoulder, note that a drive side spacer is required so for the BSA cups and the spindle without the shoulders, the cups replace the drive-side spacer and non-drive side offset produced by the shoulder on the spindle while maintaning close to the same chainline/q-factor.
I need to try it and see. Unless anyone's done it.
I have SRM Hollowgram's on a BB30 and PF30 cross bikes and have become very familiar with the intricacies of the bottom bracket. I wanted to put one of these SRMs on my time trial bike which has a BSA 24 bottom bracket and I already have both the new 109mm SISL2 as well as an SiSL 104mm road spindle with the shoulder machined off, I purchased a Zipp Vuma Quad bottom bracket to give this a try. There is currently an SRM FSA K-Force Standard installed on the bike and even though I have not installed the Zipp bottom bracket, I can tell based on observation and static measurements, it would be a waste of time unless I at least first reduce the width of the bottom bracket shell on the drive side!
