Any question answered...

Reducer cups? They will just leave you with an inferior 24mm spindled crank and the same reliability problems inherent to BB30. Better off to either bang in a BSA adapter and use external 24mm cups or learn to live with BB30.

Tip - token ceramic / ti. bearings seemed fairly resilient, especially if packed with phil grease before installation. After a wet ride pull the cranks off and clean and dry the whole shebang to reduce the chance of it seizing due to water pooling in the BB.

Youve nailed it - the adapter was what I was looking for, I just couldn't find it as I kept googling for reducer cups.

Thanks for the tip on the token bearings. I shall look into them. But the 'fun' of crank removal after a wet ride isn't really something I'm keen on. It is for the caadx after all, so wet ride = all rides.
