Has anybody actually successfully mounted the rockshox RCT3 deluxe 165x42.5 yet?   I have to return the x-fusion shock I bought due to non functioning rebound.   I'm softening my stance towards RS since there no other game in town for 120mm travel.

I dont think that shock is going to work like you want at your weight posted on MTBR.  I made the mistake of getting an RT3 and its trash in comparison to the Mcleod.  Was a waste of money.  I understand that Manitou doesnt make a 42.5 shock, but it might be worth calling them and asking if they will make a custom length.  I have that much faith in the McLeod....

Won't work. The trunnion bolts are 10mm the mount holes are 8mm. Even if they matched the air valve comes out the side and hits the mount.

That shock won't fit in there in any sort of way.

Matter of fact unless someone comes out with a trunnion shock with 8mm mounts this frame will never have 120mm travel.
I did talk to dvo and they are coming out with an inline shock called the opal and they said it will have one to fit the Scott spark. But you will still likely have to enlarge the holes on the frame.
Which is why I am selling my frame.

Thanks guys, from what I can tell, the Anthem shock was a bust due to the air filler valve location.  RS as a whole is not my favorite brand.  I like fox, but seems overpriced.  I like x-fusion, but not a full price either.  The manitou has been recommended over and over on various threads, so thats the direction I'm headed.  Seems like it could be a longer term shock than originally expected since its possible there wont be any trunnion shocks that fit.

Since it looks like trunnion mounted stocks are not going to be an option any time soon, if at all....

Has anyone considered using an offset/eccentric shock mount bushing to effectively shorten the shock side leverage of the pivot by 2mm?  I'm still trying to work out the actual numbers, but some rough guestimation puts it right around 107 mm travel.  Dropping to 6x22 hardware would allow for 110mm travel.  Sure its not the full 120, but for relatively little money, it gets you half way there.

Any thoughts or concerns about trying this?

EDIT:
I decided to pick up some 1/2" round aluminum bar stock from amazon for $5.  I'm going to drill and tap a hole, as offset as possible to maximize the increase in travel.  I think I can get a little closer to the edge by bolting right into it, rather than drilling with a larger hole for the normal 8mm hardware to go through.  Hope that makes sense.

Anyway, if I get bored one rainy day, Ill see if I can fabricate something up.  Or I may just decide its not worth the aggravation for a measly 7 to 10 mm extra travel.

Bent my 8x50 lower shock bolt anyone no where to get one at. It would be nice if it is stronger then original.

I ordered one from china...   I ordered m6 x 62, but I haven't test fit it yet.  I think I ordered it just a touch big, since they didn't have exact length.  I figured I could grind it down if necessary.

Consider using this instead of the two spacers.  It should be much stronger.

While you wait for the new bolt to come in, see if you can tap the old one back straight again.

Can anyone explain to me what will happen if I put a 184x44 shox on this, together with a 140mm fork?
Will it totaly ruin the geometry or what's gonna happen?
Only asking because I can get a new 184 shox for free..  :D

I'm running a 140mm fork and I love it.  But youre definitely going to need to run a 165mm shock.  No way around that.  I'm running a manitou mcleod shock.  Its a steal at $239 from take a hike bike shop.

I'm going to ask dvo to out a 45mm stroke on a eyelet opal when its released. Using offset bushing will take up 5mm of the extra 7mm the rest being 2mm taken up by suspension.
 I think it will work.

ReverendRockRazor can you give us your feedback and pics once you will have tested this 165X45mm shox with offset bushing?
I would install the same options with a Monarch XX to reach the 120 mm travel.
