Ok so this was originally covered in the singlespeed forum but for reference here goes:

I'm not pointing fingers, but offer this information.

If you own a Surly 1x1 be sure to chech your lower headset cup's stack height before riding your bike. The right control knobs hit, if using a Chris King ot other similarly sized headset. Cane Creek makes the "Tank Hit" headset that's the easy fix. For those of us that are either Chris King loyalists, or just plain cheap or imaginitive here's a couple ideas/solutions that I don't necessarily have an opinion on, but have been trying out:

#1~Use a Chris King Steelset(read expensive, but strong and steel cups).
A. Properly ream the headtube to a 1" depth on both sides.
B. Use a headset facing tool, only remove the excess paint from the headtube.
C. Using a liberal amount of grease, and a 1.5-2mm headest spacer
on the lower cup, install the lower cup.
D. Install your lower cup race on the fork and ride away. Periodically reinspect for any
problems or looseness.


#2~Using a headset and bottom bracket spacer
A. Ream out the inside of a 1.5-2mm headset spacer to match the i.d.(inner diameter)
of the Chris King headset race.
B. Using a liberal amount of grease, install the modified headset spacer.
C. Using a 2-2.5mm bottom bracket spacer, apply a liberal amount of grease around
the outside of the previously installed modified headset spacer, and install the bottom
bracket spacer around the headset spacer.(It should fit easily, without excess play.
D. Using grease(yeah, again, it's your "Friend"), install your lower cup race ot top of the
spacers, making sure the spacers don't shift out of alignment.
E. Reinstall your fork and ride away. Periodically reinspect for any problems or
looseness.


#3~Call Fox Shox and Convince them that:
(This neither Surly's fault, known opinion, nor suggestion.)
A. "This is not something you haven't heard of, and isn't isolated to Surly's frames."
B. "No, this isn't the frame manufacturers'(plural here, there's other frame makers who
have seen this)."
C. "Yes your forks rule, but come on, recess the right top nut, add material to the fork
crown surface, and solve this."

#4~Succumb to the little voice in your head, and sell off, or pass on your Chris King
headset and use the aforementioned Cane Creek "Tank Hit" Headset.

It is not my intention to bash or flame here.

I'm a longtime pro-wrench who knows what he's talking about, and out of the four solutions
offered, will always go with the safe and smart choices of #'s 3 and 4.


Good Luck!

I prefer option #5

Don't use Fox forks.

Marzocchi and Rockshox do just fine.

Thanks AJR and Fo Shizzle...

Completely, completely forgot I'd seen those this year. I'll contact Ventana and get a few.

Not Fox related, but I have a medium 1x1 and I just bought a Rock Shox Revelation U-turn 426. I'm thinking about putting a King on it, but I want to know if anyone has had a problem with hitting the downtube with this fork. I would like to find out if I should wait for a Tank Hit or put my bike together with a King right now. I don't want to wait much longer, but I will if I have to.

I believe the minimum "magic number" is 9-12mm....

Magic Number Explained: Measure the distance between the top of the right control knob and your fork crown race where the headset goes. It should be around 9-12mm. The Revelation runs around 5-6mm. I'd call the guys at Surly and see if they know what'll work best for you. I haven't run the Tank Hit like Kallisti and others have, I'm running a 4mm Ventana spacer that has fixed the problem.

Nothing, nothing should take the place of a mock-up first. Try and see if it's still an issue and let me know.

If it is an issue, I believe that the Tank Hit or the Ventana spacer will solve it for you though.

Bet you're glad...

Bet you're glad I said to mock it up before spending the dough, huh? I had a feeling that those guys would have this problem licked by now. Hopefully for all the frame sizes, too. :D

So, no more parts porn, lets see some ride pics. I plan on getting out now that my shoulder feels a bit better and posting some in the "Attitude" thread myself!

So does the RS revelation have more clearance than a Fox?

Can I conclude from the above that a RS Revelation will fit if the Fox does? I'm not sure if you both have the exact same frames (same size).

On a different kind of frame, I currently have a fox fork (TALAS RLC), and the rebound dail will scrape the gusset on the downtube, but only if I wind the rebound all the way out - but I don't ride it in that setting, so lucky me....

I'm now considering getting a RS Revelation and am concerned that it will hit the downtube, if the dails are a tiny bit higher. So, will it? The above suggests not. Correct?

Thanks

You really need to try a mock up first. If you have a different frame with gussetts that go far enough down the downtube, you might run into a problem. All that said, the Revelation is an awesome fork. Setup was super-easy, soaks up whatever I can't avoid and weighs much less than what I rode before, but it is still stiff and doesn't feel flimsy and noodly like a SID or a Marathon. Good Luck

Frame size...

Mock it up. That being said, Pit's on a medium. I'm on a small with the 2005 Talas, it hit, shim fixed it.

For added clearance you can also use the Cane Creek S3+5 headset or just the lower cup. It has a 5mm taller lower stack height - 17.3 vs 12.3. http://www.canecreek.com/s3_plus_5.html

The Ventana CK crown works well - I used it to get the clearance I needed for a Zocchi 66 on my small non-Surly frame.
