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 .
Make sense, granted I probably would get some swissstop bxp flash pro instead of the 9000, as I’ve recently put them on my Brompton and they stop wonders. (Granted they ruin my rims quicker)
