Hey pinkbike, just as the title says, I need your help here. I just bought a 2009 Ironhorse Sunday WC frame and went to install a 2012 Rockshox Vivid Air into it but the shocks air can rubs up against the inside of the frame so I'm not too sure what to do as I can not mount it in the top pivots. I though that the Vivid Air was the same width as a coil shock? The previous owner had a 2011 Rockshox Vivid Coil so I don't see why its doing this. Any suggestions on what to do? I've thought about grinding that area out to make clearance but i don't want to ruin or weaken the frame. Here's some pics:

My new frame - 2009 Ironhorse Sunday WC and 2012 Rockshox Vivid Air. Looks great and I m sure it ll ride great but the shocks air can rubs up against the inside of the frame so I m not too sure what to do as I can not mount it in the top pivots. Looks like I ll be doing some filing and grinding down

As you can see, all i have is like a 2mm gap between the frame and air can and that is without having it even close to lining up to the mounting holes!

Keep it raw so we can be twins Wink


Shitty deal. I certainly would not want to take a grinder to it. I'd just run the viv coil...

Ahhhha i like that idea Wink but i want a stealthy looking bike with a flat black colour scheme! But as for getting a coil Vivid, i would but i just blew $500 on this Vivid Air so unless i can make back what i paid, looks like ill be doing some grinding over the christmas break! I think this is the only Sunday with a Vivid Air too so i want to keep it unique Razz

I can lend you a shock if need be. until you sell your new Vivid for something that will fit. Just an option, especially if you would like to ride it asap. Ill be home later today, just heading out. We'll get together!

You got no option but to grind the frame down.

'Then unless you are willing to grind away at your new frame there is no other options , is the Air shock bought from new? If so get a refund if not sell it don't take a grinder to your frame man!
If you are willing to grind that much material from your frame for the reasons you stated above , regarding being ' unique ' and ' all black' you are mentally challenged Razz

Not gonna fit bud. I wouldn't recommend grinding your frame . If you really want air go dhx or cane creek maybe...Just sell the shock as new and get your money back.

Im stelling you, get the dueler shock dude. It is 400 bucks with a ti spring, nothing but good reviews. No pedal platform so it is one of the most sensitive shocks on the market.

I had a sunday before and if i were in your situation i would grind the frame down a bit. That section on the sunday is quite beffy so i wouldnt worry. Look at what others has done to the sidewalls. The air shouldnt be that much wider than the coil, only the valve should be wider in diameter than a coil sprin atleast according to sram, the coil version had problems with fittning if you used a higher rate spring than 400.

+1. I have one of those myself and it's better than any DHX, Roco or Vivid (I haven't tried a Vivair though) shocks I've tried. I know about a guy running a Dueler on his Sunday, looks like it's working good for him. Smile

I agree! Hey everyone, with a few modification of grinding and filing down the CNC machines seat post area, I was able to get my shock to fit. It has like 3mm of clearance on both sides which is good enough and the shock can travel through its whole stroke without any problems. Big thanks to oldschoolj for helping me make this happen!

2009 IronHorse Sunday WC with a 2012 Rockshox Vivid Air installed. After 10 hours of filing and grinding down the inside on the CNC seat post area and flipping the DW-Link since the shock wasn t get a full stroke length it finally fits. Big thanks to oldschoolj for helping me out to make this happen

When he says filing and grinding, it was with a very fine file and Dremel with a fine grind, almost polishing bit. No heat and minimal removal of material. It also helped that he discovered that the DW-LINK was installed upside down by the previous owner resulting in the shock losing about 1"-11/2" of stroke. So surprised once we flipped it, everything came together perfect. can't wait to see the full build, the parts list is damn awesome!
