I had the Z1 FR SL which were the QR 130mm cousin of the forks in the article.
I rode them for 3 years or so including one summer where I spent the whole summer in the pointy bits of Europe. I got them to work acceptably well but OH MY GOD they were a pain to set up.
2 different shock pumps, a odd female to male adaptor to access the valves, I think an extra chamber that you had to remove the lockdown (not lock out, lock down) lever to access also vaguely affected the rebound damping. No Compression damping adjustment.
A less patient man would have thrown them into the sea!
They were replaced with a Rock Shox Pike U-Turn 454 which was better in every conceivable way.
