Still trying to wrap my head about the BB issue. Called the Praxis people thinking they might have a good solution. Basically, they said they don't, and they don't even offer a crankset that works directly with the BB30a on the CAAD12. So it got me thinking: Are there any options that don't involve either a design compromise or paying boatloads of money? If not, then I'll stop here and buy a complete bike. Otherwise, I'll proceed on and continue with my project.
Thank you,
