I have a Klein Quntum II with Chorus (8spd) and a Pinarello Veulta with Veloce (9spd) The Klein is too big for me (59cm). I was thinking of putting the Chorus on the Veulta. I have never tackled BB before. Will the 8sp Chorus cranks work in the Vuelta with the Veloce BB? If not what BB do I need? Will I have other problems as well that stand out? I would move over the ergoshifters as well so everything would be the same.
