Contacted Risse for a quote.
I'm going to order a Genesis unit with freedom plate for my XP-8, $246 US, £127UK at current exchange.
That price includes shipping to the UK.
The Astro was a little bit to steep for me, I'll try the Genesis and if I like it might trade up to an Astro at a later date!
Any comments or advice!

I have a genesis for sale currently - very good condition, not with cone, but why not just order that part from Risse - I think it's only $25 for shaft with cone. I don't think my Genesis will fetch much.

I recently got a genesis and an astro5 (front and rear)
My only problem with the front is that it doesnt quite clear the existing fork structure, im going to have to strip the forks and grind a small section away from the top swinging plate (dont know what its called!) It only clears the valve if the valve cap is left off and the plate is also touching the shock when no load is on the bike.
I'll try to take a snap at some point.
Of course it could be something ive done wrong, but im pretty sure it went back together ok.

I put a genesis on my carbon crosslink and it all went well, doesn't snag anywhere - although there wasn't enough clearance around the shock for a neoprene shock cover.
What type have you put yours on. If you can't sort it we could do a compare.
cheers

is the fork on the 856 the original girvin vector or a later crosslink???Did you order a shock to fit the respective fork?The noleen croslinks were slightly longer "upstairs" than the vectors or girvin crosllinks
-
No worries there Kiwi its Crosslinks I put on the Xp-8

the shock for the girvins(vector or crosslink) will (or should be) slightly longer than the shock for the noleen crosslink.Thats my understanding anyway.Perhaps you ordered (or got) the wrong front shock???

Mr 752..perhaps you should enquire about an x57 shock....as far as i know the taper is the same...I have asked risse a couple of time to confirm this but I reckon the taper never changed .The freedom plate is to make the x55 shock fit "OVER" the top of the taper...as the x57 shock came later they did nt feel it necessary to change their info....I reckon an x57 shock with built in taper would be the way to go on a x56 type strut.As long as someone can confirm the taper is the same!
-
pretty sure the NR4 that was on my way big 857 is the one now on my 855, so that would confirm it wouldn't it?

only if the 855 now has an x56 strut,otherwise the taper wouldnt mount to the flat x55 strut

Kiwi,
I can see where you're coming from with this and in my opinion I would have thought from an engineering prospective machining the mount to fit in the cone would be a superior method than to fit the freedom mount over it.
I'll contact Risse again and ask for some pictures of the freedom plate.
-
check out the pis of the x57 shocks too..perhaps risse can give you the dimesions of the "cone" and you can measure up the xp8 shock.My risse has the freedom plate.....
-
oh, must mean I have an 856 strut as it has the conical shape buiilt into it?
-
Done a bit of a measure on the ODS unit
The adjusting nut is wound down a little so theres probably a +/- 5mm or so on the dimension.
Can anyone with a x57 type rear shock give me dimensions on theres, similarly anyone with an x55 rear end. Thickness of the mounting plate on the strut as well.
If what Eds saying about his 857 fitting his 855 is right, unless he has a x56 back end the cone should be the same!

OK, my NR4 (which was on my 857) on my 855 is also 189mm but there is an additional 6mm between the base and the strut which is the top of the cone (which is integral to the NR4). If anybody can tell me how I might know if I have an 856 strut or not I'll happily check.

Ed ,if you have a cone shape in the strut its an x56 strut....someone always used to come to the rescue here and post a pic of a x55 strut and a x56 strut...
-
I think i better contact risse then about my shock fouling the fork.
I'll get a pic up of it first so you can all see what i mean, maybe others have ahd the same issue.

well I've learnt something about my 855 today then ;D

Excuse my ignorance but will this shock fit the rear of an oz x. The NR4 on it measures over 200mm. And I seem to recall something about carbon bikes needing a rod and spring type shock due to their flex.?
Any air shock will work as long as it clears the mounts. The flex is side to side. I have found that a more supple shock with longer travel nullifies the flex. Actually becoming a winning combo in my experience.

I have also been pondering purchasing a genesis with a 957 tapered end for my 856. Is the 957 and 856 cone tapers the same? Will it definately just "bolt" in?
-
I think the tapers are the same.
-
i also think the tapers are the same.....I have asked Risse this question but never received an answer...

they are different cone ends and will not interchange bewtten a 856 and an 857, yet you can get a genesis for each. i think they are a great substitute for the NR and are an improvement. the astro and terminator are very fine, yet this genesis is very nice for XC. plus it is owner servicably friendly
-
are you sure? I'm pretty sure I took the NR4 off my old 857 to put on my current 855 (with an 856 strut) and it fits fine...
-
I replaced the NR1 that came on the 957 frame I bought with a Risse, and then put the NR1 on my 657 (short swing arm, pivot behind bb) to replace the ODS and that worked fine. Don't know if that helps.
Ade
-
well the 657 was actually a x56 frame,so surely was an x56 strut as well...I would expect the 957 to have a nr4 or at least a nr2./Any how that seems to suggestt he cone is the same...what is your experience Carbon Angus to counter our beleifs?
-
I checked a couple of struts last night. The cone end on my 856 strut, and 957 strut are the same. The only difference was the length of the strut. The Noleen shocks as well as Risse have machined in cones. The ODS, GDS, and friction dampers have compression coned sleeves on a straight shaft.
I think the Risse freedom plate is the adapter for the elastomer strut.
Terry
-
the freedom plate is just a big flat washer that covers the cone depression in an x56 strut so that a x55 risse can be used on a x56 .I think an x57 type risse would be a better solution for a x56 as long as we can confirm(which terry seems to have done)

andy the problem may be that you have a risse shock for a noleen crosslink which may be too long for a vector or girvin crosslink

I must have had to many red wines this night...i think i have this completely the wrong way round....
