Just twigged, the Arione on my tourer is lighter and longer than the [CP]Vitesse on my racer which is more comfortable - so swap them. That theyre both Fizik helps - same rail markings; glad I remembered to allow for the different heights from rail to seat. The racer is is ready so I'm off to test it, finish the tourer when I get back.
I know this hardly counts, but it is the thin end of the wedge.
PS where should the extra length of the Arione be?

I wronged the Arione, the OCR 0 carbon fork/tail really cuts the vibration compared to my steel bike. Makes me really glad to have never "enjoyed" a full aluminium frame.
