Hi !

Just got a 2006 sunday frame and having some problems with that. I found something with search, but still have some questions. First is that lower dw link(the red anodized one) has some play in rear pivot, it's kind a floating like 1-1.5mm, it seems that spacers might be too thin. Is this a common problem? Would it be okay to just put very thin shims to correct it? Other thing is that 5th element bushing seem to have a lot of tolerance, upper one is has already very small amount of play and lower one is super-tight. It also seems that even the lower one has some play, but I'm not sure about that. Bike has not been ridden at all yet.

The other thing is i need to replace my headset i know its the fsa orbit is 2 as standard but does anyone have any siggestions as to whats the best to use.

Cheers

anyone knows about the new linkage?
when it will avaliable for regular people?
I just received a reply to an e-mail I had sent to Ironhorse asking the same question. The word is that the '07 linkage kit upgrade will become available late February and will retail for around $200. Hope thats true, I really want to upgrade.

I just called ironhorse and they told me the new linkage kits will be available late february for about 200 as well...Seems pretty steep. I might try to modify the original links myself to work with non 5th shocks. Anyone tried this yet?

Also, I called FOX and asked about sunday tuned DHXs. The guy told me that they dont exist. Has anyone actually bought a "sunday tuned" dhx from fox?? Is it possible that I talked to a guy who gave me incorrect info?

All the Sunday sizes are coming with a 300 spring on the rear shock.
Doesn't a 19" bike is for bigger riders? Don't they need a stiffer spring?
Or is the 300 good for every rider... ?
I'm 72 kilos. On a 16" Sunday, what spring do I need??

What you need to do is buy a stock DHX, send it in and request that tune.

I'm running a 350 Ti spring on my medium Sunday, @ 6'-1" & 215 lbs with kit, works perfect for me.

hey mate i had the same prob, yeah you can use thin shims to make it work, but if u can get a machine shope to make you some spacers to fit the frame exactly...with the shock a batch of the 5ths had a problem, i got my hardwear from tftuned.com, great guys they will sort you out....

I put in two 0.25mm shims, they seem to do the job. We don't have official 5th element service in finland, but I talked with importer and he is paying for service in local bike shop, so it should be fine. Btw, there was also something internally wrong with the shock, it was making terrible noises and almost locked out with more than 50psi pressure.

83mm is the bb width, has nothing to do with the cups per-se.
If you are talking about an ISIS bb then the spindle should be 128mm as any 150mm (non asymetrical) rear end will have a 57mm chainline.

113mm spindle = 47.5 - 50 mm chainline
128 mm spindle adds 7.5 mm to each side = 56-57.5 mm chainline.

I'm 185, and am running a 350 with almost zero preload - am very happy with it. At 220, you might need to go with the 400. Base your spring weight and preload on your sag and you're golden.

The bearings are all ABI/Enduro type cartridge bearings, so if you really want to, you could try to -CAREFULLY- remove the dust shield (plastic cover in the middle) blast some de-greaser in there, spin it, blast it with compressed air, then re-pack it and put the shield back on.

Thing is though - if you tweak the shield while removing it and bend it too much, you won't be able to put it back on the bearing.

The alternative is to tap out the bearings and just replace em'. They are between 10 and 25 USD each.

Hi my friend has a 2006 7.3 and he wants to know if a roco world cup will work without needing to be tuned. And is there any companies that can tune a manitou 6way? Thanks

Would a Manitou Evolver ISX-6 fit?

Which size would you recommend?
I am 5'8" with long legs (inseam 86 cm/34") and also longer arms (64 cm/25,2")
Size S with a 60 mm stem or
Size M with a 40 mm stem?

Does anybody know the distance from center of the BB to the center of the top of the headtube form size S or M?

Thanks a lot

have not tried that specific shock, but it is based on the revox (with the 90deg piggyback mounting) which definitely does not fit.

You'd probably be more comfortable on a medium, as the small is *real* small. can get you the "front center" measurement when I get to work. :)

we spoke with them about getting some test shocks, and then the whole HB thing happened. we try to test out as many shocks as we can get our hands on, but when a shock-maker changes their design so it appears it *won't* fit on our bikes, it's hard to keep up with what fits and what doesn't. they don't have the large adjustment knobs that the Revox does, so it's possible they might but I'm not holding my breath.

Can you drill the 06 links and make them 10mm, like the 07?
Drill the links, drill the bushings and use a 10mm bolts...
Did anyone try it?

I don't have access to FE analysis but I'm guessing this would be a REALLY bad idea.

Any drilling you do could weaken the links.

Rumor has it the 07 Link Kits should be available as early as March, but it's still just a rumor - some guys have contacted the I.H. warranty dept. and this was the response they got.
