I have a SRAM XO Der and XO Gripshifters. After initial setup and a few adjustments over the next month, there has been no real need to readjust the shifting. Maybe twice in the last three years, while riding, I have turned the barrel adjuster an eighth of a turn to fine tune the shifting. As for 'retuning' on the workstand, haven't needed to in 7500 miles. bk
