Bernard, what exactly did you have to hammer, saw, and file? Assuming that E.13 is going to become an LG1, you could run the chainring bolt spacers that most people put on the outside of the chainring on the inside to give the cranks a more normal chainline.
He removed the bb tension device that is part of the non-drive side arm on those cranks. I have not looked at them, so I do not know what is involved to do this...but I would imagine it was a bit of trial and error as the crank bolt needs to be bottomed out, and at that point, the bb pre-load needs to be correct....this is the same problem that plagues RF cranks/bbs currently.
I was thinking the same thing about putting the ring on the outside at first... but 'super off the top of my head figures' put his chainline at 52mm ish. Moving to the outer mount would add 5mm = 57mm. Ideal for a 150 rear is 55mm so it is possible he is closer to 55 right now than if he moved the ring, especially since he milled the ring to shift it outward.
It will be interesting to see if the cranks clear the chainstays over time under load (think 73/135 intense M3).

I think right now he's probably ~2.5mm away from 55mm either way. I have a Sunday in the mail right now and might try this with the ring mounted in the outer position b/c I only run 5 cogs.
Has anyone tryed this or have any feedback? Just curious. Sorry for the pinkbike link.

Push no longer builds the race system that is discussed in that article. I did have one on a DHR and it felt great, but what they currently do is a little different (they do not remove the boost valve).
FWIW:
I have exchanged a few e-mails with Darren at push about the Sunday in particular and they assured me that they would/could do things to improve the stock DHX. He said they had some issues with early Sunday tunes having too much rebound dampng but that is now corrected...

Yep - true that davep.
Dante (when he was with IH) had a DHX with a Factory Race System that was given to the IH offices by Darren as a test shock. This was back in the summer of 06' I believe.
Pretty sweet shock with tons of tuneability, but it wasn't quite where Dante wanted it to be. Haven't spoken with him in a while, but good to hear that Darren has been working on improving the DHX tune for the Sunday.
Everything that PUSH makes is top-notch and Darren knows his stuff - I'm actually getting my DHX PUSH'ed and when it finally comes in.... my 08 Boxxer.
But that's another story.

davep - Isn't the correct chainline for a 150x83mm bike 57.5mm (not 55mm)? That's what I recall setting my sunday up at, and also the recommendation - but it's been a long time since I built my bike too, so my memory is vague.
But yeah IIRC, correct chainline is 57.5mm, partly why they only spec Shimano or FSA cranks, as Truvativ stuff leaves the chainline at 56mm which is less than perfect.
Correct me if I'm wrong though.

135 hub = 47.5mm [(hubwidth 135mm/2) - (cassette width 40mm/2)]
chainline difference for a 150 = 1/2 the difference in hub width = 7.5mm......47.5 + 7.5 = 55mm
Things have gotten wierd in the last few years, as most cranks for 135 hubs have pushed out to 50mm chainline due to the (IMO) spacing of outboard bearings, as well as very oversized seat tubes tha place the front mech to far outboard for a 47.5 chainline.
I dont know that it matters a bunch. With a single ring up front, there will be a lot of chain angle at cassette extremes no matter where you set the chainline. I suppose if you ride mostly in the smaller cogs (think DH) a wider chainline would minimize wear.

hi everybody
i´ve got my 2nd sunday it´s a 08 black one.. and i wanna make some aerography job in the headtube... i just wanna paint there the flag of my country (like peaty´s champs bikes) but i´m wondering if that will void the warranty of the frame... i won´t use any kind of chemical solvent or sandpaper neither i´ll just paint over the stock paint job (black anodized i think)
let me now... before i paint it
thanks a lot...
Me.

Naz' - what's up?
Valpo looked like lots of fun this year - too bad I couldn't make it. Sorry to hear about Brendon's wheels too...
If you want to paint something on the headtube that won't be effecting the anodizing - that's fine. I'll do some research for you to find out what types of paints will work with the ano... Actually come to think of it, it's pretty hard to paint over ano and make it last. I think a good "Plan B" would be to have a sticker made up of the flag.
I'll get back to you with a PM tomorrow about the paint.
Cheers!
Somebody asked about shock tunes for a VIVID and there was some debate as to the Rock Shox tune for the Sunday. Because of the dw-link's position sensitive anti-squat curve, and the bike's leverage rate curve, Rock Shox developed the A level tune for the bike.
Keep in mind that the Sunday was designed to use a damper with some end travel ramp, so set your shock up accordingly.

End travel ramp - ohhh yes.
Just wondering, if my Sunday was ordered two weeks ago, will the lower link be Vivid compatible or is it going to have date with a dremel?
I just got my 08 frame last week and it appears to have the 07 lower link - came with a DHX.
Thanks for the info. Dremel time.
Did you order a frame kit or a complete bike? If you ordered a World Cup then yes it's coming with the Vivid. Frame kit wise, the Factory frames are coming with the DHX and later on when they switch to World Cup frames they'll have the Vivid.
Woa - woa guys... hold on... just because the frame came with a DHX doesn't necessarily mean that you have the 07' lower link.Thanks for the info. Dremel time.
Let me find some pics before you start voiding warranties.
Jason - you rule.
Totally swamped with work, but here is the pic of the 08' Vivid link guys:
NOTE: I will add this to the frontpage and update with other goodies as well during my time off next week.
So - if your lower link looks like this - no need to Dremel. It will fit the Vivid no problem.

Mine is definitely the 07 link. No worries though as I am happy with the DHX.
Thank Carl at IH - he's the one that snapped that pic for me.
My lower link was a 07, so I simply filed it to clear the Vivid.
ride on..
Looks like a pretty minor mod Luc. Is it to clear the ending stroke rebound housing?
yup - like I mentioned in my vivid article, some frames might clear, so might not. just double check..
I'm still tapping my fingers semi-patiently waiting for it to come. I was definitely going to check before voiding my warranty. I just want to have an idea of what I'm going to have to do.Woa - woa guys... hold on... just because the frame came with a DHX doesn't necessarily mean that you have the 07' lower link.

Just so you know, if you wanted to run the Vivid we have just lower links available seperate from the linkage kits. They run $55 plus shipping.
referring to DW on the other page, he mentioned the A LEVEL tune for the vivid...
is this tuning different from the A TUNE which sram has in their parts catalog?

Where can i ask questions about the marketing and export ... no technical question?
Does anyone have a recommendation for a tool or a hardware store tool (threaded rod, nuts, washers) for removing bearings from the Sunday frame?
Pyro - CarlE should be able to help you with those kinds of questions.
As for removing the bearings, as rawcan said using the proper sized socket from a socket wrench set and a C-Clamp will do the job - just go slowly to make sure you aren't damaging the frame!

I have a 07 Sunday WC with the false spring. With my gear i weight about 70 KG (155lb).
At the moment i have a offer about one 275lb and one 350lb spring. Can i buy one of the two or should i buy one 300lb spring.
I have one 500lb spring to sell or change!

i would get a 300 at your wieght
A very good friend of me weight about 75 Kg (165lb) and rides a 2006 Sunday with a 450lb spring.
He said to me i should buy a 350lb spring and not a 300lb because the bike with stronger spring is more ready to race... ???
I don´t know what i should do....
