Don’t understand that question, but they are good brakes tbh, just annoying if they’re not centred and also the braking force is mainly from one side (apparently)
I had the 105 version of them with them brake blocks and yes they were not that great so I change them for the 9000 brake pad and shoe what a diffrence .
But don't you currently have the single pivots with arms that move on a thrust bearing? (Rather than a bushing). They are supposed to be decent if so.
