Morning, I've been looking on the interweb for droplinks and I'm seeing a few variations, all part no. 1J0411315 but with various letters at the end for different revisions. I've got an AGU with 21mm ARB. Some internet shops advise particular drop links (1J0411315E & 1J0411315G) won't fit, stating they're for 23mm ARB whereas 1J0411315C will (and possibly 1J0411315H) Reason I ask is that when looking at aftermarket drop links there's no mention of them fitting specific sized bars. Anyone clear things up for me?
