Thanks guys,
Loco – SKF as far as I know. They differ from the standard in that they dont fit flush, the top 2-3mm is slightly wider than the aperture acting almost like a washer.
Solamanda – Yup tried that after the first set of springs got screwed up. Didnt make any difference 🙁
Ho hum, guess they could just have been out of tolerance or part of a duff batch, which of course can happen. Just seemed weird. Also the foam rings were totally different material and almost seemed too soft and were thinner.
The only worrying thing is that I heard a rumour Rockshox are to change their standard seals for the SKF ones….but not sure how true that is.
May have to put it down to experience.
