I'm pretty sure they will not work with the 10mm Sunday/6point/7point hardware, but someone else needs to comfirm this. I would like to get some for my 6 point but am fairly certain I will need something custom made.
There are lots of places that sell custom offset bushings:
Offsetbushings.com
Burgtec : http://www.burgtec.co.uk/products/offset-shock-hardware/burgtec-titanium-offset-shock-hardware/
and an ebay dealer: http://www.ebay.com/sch/i.html?_trksid=p2049127.m570.l1313.TR0.TRC0.H0.Xoffset+bushing&_nkw=offset+bushing&_sacat=888&_from=R40

being just a few of them.

As far as I know, the "custom" aspect of these is the overall width of the hardware, to accommodate different shock mounts on different frames. The diameter of the hardware for the bushings is only available in 6mm or 8mm. DW Iron Horses use 10mm diameter hardware, and apparently the amount of offset available in a 10mm application is minimal and basically nil, thus no one does it. I do believe though, that with some clever design and machining, you could utilize some smaller diameter hardware.

It will depend on the year of your Sunday. 05 and 06s had 8mm hardware that allows offset bushings, 07+ linkages use 10mm hardware that does not.
I can't imagine why you'd want them on a sunday, and I seem to remember dw saying that the fender mount/ cross brace on the rear triangle would hit the seat post at bottom out if the shock is any shorter than stock.

I can't see how is that possible to use offset bushings on this frame, since the wallthickness of the axle is 1,35mm which goes through the eyelet...

However I realy don't like original design of the stock/original mount hardware. It wares out the frames connecting faces, since that 1,35mm of hollow, round steel hold aganist the twisting forces on the soft aluminium.

I much more like the "peterverdone" style stuff, like on this picture:



Much bigger aluminium to steel connecting faces.

The offset bushes on a Sunday is a no go! This is if you want a sound and crack-free frame. And the problem is not within the 10mm hardware. It is in the frame design as a whole - meaning that if you put offsett bushes, the frame will bottom out before the shock. I"ve done the measurements on my Sunday and it is not possible to use them. But given the original geometry numbers of the Sunday, one could only keep wondering why you'd need anything else than an angleset for this model... :) ;)

You have to remove both rear braces entirely, it is very simple. Just smooth out the cut edges when you are done to remove any stress risers. If you do not remove both braces entirely it will hit the shock.

I have not seen one fail yet, but obviously you do this at your own risk. If it's any consolation I believe those links are cold forged 7075, they are very strong.

It should look like this when done:

What if I wanted to use offset bushes on my 6 point? Does any body have any experience using/finding offset bushes for the 10mm frames?

Did somebody ever have problems with a cutted/trimmed linkage on a Sunday?
As Udi said they are very strong so just cut them and make sure there are not any edges left ; )Great choice ,RC4 is a really really good shock for this frame .I've been riding mine for 2 years without any issues.
I just fitted a Vivid Air 2014 and had to trim it down even more so just be brave and do it : )

Thanks for the reply, i had to remove just a bit of the two braces because i installed an Elka Stage 5 and it needs less room.

That could be made to fit with 8mm bushes from an Enduro Roller kit & corresponding strippers - the 6POINT isn't needing severe geometry changes though. A 180mm Fork, a 2.5" Tire only in front makes 66.5-67.0deg headtube, which is fair.
Mine is set up with 8.75 shock, Lyrik in 170mm with an external lower headset to accommodate the tapered steerer, and i have measured my head angle at 66. Which i think is very reasonable. Problem is, with the 170mm fork and external headset, its raised the bottom bracket a bit. The geo sheet(which I know has several mistakes) says the bb height is 13.75 and I am measuring mine at 14.2, which is pretty tall by today's standards. Still getting little odds and ends to complete the build so I haven't had a chance to form an opinion on the ride.

Is there any chance in hell that a 19" Sunday would fit a person who is 5'9"? (32" inseam). Or would it simply be too tall? I am interested in having a longer bike, as that seems to be the trend these days, however, I'm deeply worried about stand over.
Wait for the carbon front end :) We were planning to show this at the Cairns World cup, but I have been out of action with broken ribs. I will get you guys some CAD images maybe.

what's the frame size of the carbon sunday?

same 9.5 eye to eye shock?

is the 83 mm BB threaded or press fit?

is the head tube 1.5 straight or tapered?

is the head angle fixed at 63 deg?, no need to use angle set headsets?

is the seat post diameter still 30 mm or 31.6 mm?
(consider options for a dropper post, who knows someone may use it as a trenduro trail bike)

is it with internal cable routing? (wish)

is it with integrated fork bumpers?

As far as i remember, the carbon front end would have custom geometry, meaning every buyer could get the geometry he needs - just order it and Zelvy produces it. Or have i understood wrongly?

Well, may be i understood wrong. Can't really remember what they meant by custom geometry - whether they'll produce a fixed-geometry front end on people's advices, or if they'll make different geometries per each buyer's request. I am for fixed one as well, as i think the Sunday only needs a fix in the HA - get it down from 65 to 62.5 and it would be nuts!!! :)

Heya guys any info on the weight : )
How much pounds we gonna drop comparing to our front triangles?
Also any ideas will newer shock will fit it without problem eg VIVID Air, CCDB Air ?
Cheers

msaman, you have reuse old rear triangle plus linkages from original Sunday.

Zelvy frame looks nice, though the bottom part needs some modifications, aesthetically it is too much of plain "walls". I understand that it makes building easier by using simpler shapes of CF modules.

Hi, I just bought a Sunday and set it up with the Fox DHX air that I had on my previous frame and I saw that the propedal dial hits the link on full compression. Has anyone had this problem? Anyone knows if I can just take the propedal dial off and run the shock without the dial?
The specific shock is this one:

Yeah, I believe you can remove the dial and it no longer interferes (or at least I recall someone racing here on that setup with only the dial removed). Alternatively you can just dremel or file away some material where it would contact the link, it would only require a small amount of material removed, but since that adjuster isn't very useful on a DH bike it's probably easier to just remove it.

Either way, bottom out the shock with no air spring pressure (don't empty damper pressure) carefully to make sure there is no contact at bottom out.

AllStar - keep an eye on your DHX Air while riding. During testing session between 2006 and 2007 the DHX Air was found to be a poor match for application in the Sunday due to overheating. I realize this information may be the last thing you want to hear considering you have committed to this shock for the frame, but to be safe this is something you should be aware of.

Damn, thats bad news.
Anyone knows if a Vivid Air R2C would fit without any issues and without cuting or grinding the link?
I may have a good deal on one of these:

Depending on the year of your frame it may fit the link with no issues, but it won't fit between the uprights of the frame. You'll have to grind on the front triangle to make that fit.

I dont like the idea of grinding the frame and/or link so I'll guess I'll try to remove the dial on my DHX air and see how it goes, and if I have any issues with it I'll probably go with a coil DHX 5.

Since the fox dhx air was replaced with float X CTD, is it advisable to use it on a sunday?, it is available in 9.5 inches eye to eye. or is there a limit (trail bikes only) on rear wheel travel on its application/usage?


Zelvy said from their FB they will show the sunday carbon front triangle at round 2 WC in cairns. no photos in the net so far.

To ensure that I'm understanding your question correctly, you are asking if a Float X CTD is compatible with the Sunday?

If this is your question, then I would say "No" in that it would also suffer from overheating issues. Air shocks that would fair better in the Sunday would be large volume air shocks such as the CCDB Air or the Vivid Air as these shocks were designed for FR/DH applications.

The catch, as previously mentioned is that these shock bodies will not fit in between the seat tube uprights. Bear in mind dw originally designed the Sunday's dw-link suspension around the Progressive 5th Element. If you have no idea what that is, then YES - that was a long time ago, and YES, this shock no longer exists due to it being discontinued around 2006 I believe.

Well, a Vivid Air requires more gringing on the frame itself than the CCDB Air - tested and proven. :) Here's the amount of grinding required for a CCDB Air:

whoa nice!,

How about a dremeled/ grinded rear triangle, reference pics to fit 650B rear wheel?

sunday is the undead.

Dremeled how? To accomodate the 650b standart? i think there's no meat to take from the rear triange to make this modification.... And i think the Sunday should stay 26 inch only! I was smiling when a buddy of mine was saying the Sunday is the perfect frameset, but then i bought one and understood what he meant. :)
The only real change the frame needs is the head angle. Will now go and see what another friend of mine have done to his Sunday - word is his shock is a floating one now... :D
