Welcome to the new and improved Proflex / K2 Tech Forum!
the risse i got from Harv(I wonder whats happened to him) that he had on his 957 has the freedom plate,which just sits flat on the top of the strut without using the "cone" i dont know what the difference is between the x56 and x55 strut that makes the adapter necessary on the 56 strut.I have also wondered if an x57 shock would fit the x56 strut making the adapter redundant.I have emailed Risse twice about this but never got a response.So if anyone out there has a x57 and a x56 try the 97 shock on the 96 bike and report back,then any prospective risse buyer can be told to get the 97 shock and do without the extra adapter.
Shovelon is the man!!! (but how do you pronounce his name?)(BTW it is Mi-ZU-nole) Mizuno + Nole...
