Often you will find bad shifting as mentioned here because the cable has been pulled to tight when tightening it to the RD. This throws out your limit screw settings badly. No matter how hard you adjust the cable tension on the barrel adjusters it won't help. Try replacing the cable to start with(this is the cheapest fix and can only help) then only use finger tension when pulling the cable tight at the RD.
I wish they would wake up and make it minimum qualifying, I'm so sick of uneducated unfit wallies making it an abortion for riders trying to be competitive, safely !!!! So its a lotto, make them put into cycling first by riding other races ! Qualify dammit !
