I did upgrade my 9 speed Dura-Ace cassette (from 11/23 to 12/27) and changed chainrings, cassette, chain prior to SRAM road group becoming
a more accepted option.
I knew my brifters were starting to wear out at 9+ yrs. old. I started saving for SRAM Red. Finally, upgraded to Red when DA brifters where worn out at 11 yrs. old.
