Reading an English translation of the thread, it looks like you’re asking about a replacement shock bolt? I used a BetterBolts 40mm Transition shock bolt on my 1002. Although this is my first time ever using a titanium shock bolt and I haven’t been able to ride it on trails yet, I have faith in BetterBolts’ quality.

What’s this little protective flap you have installed there? I’ve been looking for something like that to protect the cable ports there on my FM1002 — I’ve already drained a fairly ridiculous amount of water from the stays after washing the bike and can only imagine how much gunk could build up inside there over time!
