Looks like a light combo and Enduro today confirmed it will work with old BSA style bikes.
Who has taken advantage of this combo?
Hollowgram cranks. (Add 17g if you want a power meter attached)
Enduro XD15 BKC O6O5
Im thinking of putting it on my BSA CAAD9.

Have you seen an actual picture of the product? im having a hard time picturing it because a bb30/pf30 crank spindle is quite a bit shorter for outboard bearings to work and I would assume you would need to go outboard to have a 30mm spindle work in a bsa threaded shell.

See the specs here:

Note the BB compatibility.
Also, the spindle is compatible with Hollowgrams; same interface, just longer and without a shoulder on it.

Would I need a mountain bike spindle to fit BB30 Hollowgram to a CAAD9 BSA?
I emailed Cannondale Australia and Cannondale USA and they admitted they didnt know the answer.

This has been mentioned before. I also thought I was a genius until I looked in to it and the Q-factor and chain line would be COMPLETELY off.
How much should this be repeated again and again?
True BB30 crank (which Hollowgram happens to be) cannot be mounted on a BSA BB frame without serious modifications which would make the usage non-optimal, to say the least (such as chainline issues and others).

Minimum bike categories required in the stable:
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
Once more for clarity - it will not work!
So until someone introduces BSA 386 adapters , for those who are still not convinced, the only modification that will possibly afford near optimal results requires removal/machining ~6.5mm of material from each face of the bottom bracket shell. So while that is probably attainable for alloy frames, maybe not so much for a Ti frame, and simply a none starter when discussing a carbon frame that wraps a billet aluminum bottom bracket insert.

would chain line not be the same if your bike was using 135mm rear spacing like a mtb, assuming you have the mtb spindle?
or does the mtb spider have a different offset?
