Hey up Nobleswood, yes they are the original caps I had.
I actually sourced the new kit thru uk ebay, the suppliers were an Italian company: Sestamarcia Racing Parts. I think they’re based in Rimini. Despite having the initial problems, they were very helpful in rectifying the issue. Good communication, and in English, so I don’t see why you couldn’t contact them directly.
I’ve put about 50 miles on the new kit so far, yesterday was purrfect. The lack of dive is most noticeable and they feel tight, yet ‘supple’ somehow. The brakes feel ace too now for some reason!
