I've searched the forums and found some vaguely relevant answers but nothing definitive.

I recently added a Rohloff to my Surly 1x1 singlespeed and in doing so had to remove my bash guard, change chainrings and move the new chainring from inside the spider arms to the outside (where the bash guard previously lived) in order to nail down a proper chainline.

Where I had a flush chainring-spider arm mating on the inside of the arms, by moving the chainring to the outside I no longer have flush contact between any of the four mounts.

I'm also using stainless steel chainring bolts with Loctite.

My question is:

With plans of long-distance, off-road loaded touring, will mounting the chainring this way cause me problems? If so, any suggestions on how to fix it?

Thanks!

I don't expect that you'll have any problems. The only issue is that you needed to make up the thickness of the bashguard with a spacer. If you don't like using the psacer buy a set of single speed chainring bolts which are roughly 4mm shorter.

Also if your chainring is counterbored on one side so the chainring bolts fit flush, reverse it when moving from inside to outside so the counterbore is on the right side.

Rohloff's smallest allowed ratios mean that you usually need a large chain ring anyhow. This problem should not arise if using these larger rings. I'd fit larger sprockets front and back to keep the ratio and allow the use of a larger front ring which would fit better.

I see you've got a 34t ring. What rear sprocket are you using - if your planning long tours, I wouldn't take the risk of using an unallowed sprocket ratio.
