Having read reviews that suggested that much of the superior shifting performance of DA9000 over 7900 is down to the cables I was wondering whether anyone has upgraded their cables only & noticed this claimed benefit? My 7900 cables are less than 12 months old so not due to be replaced due to wear & tear just yet.
