I want to use a single-speed freewheel on a setup that perforce has a non-straight chainline. I wanted to use this chain:

due to the available colors

Is a bent chainline the kiss of death? Will a 3/32" single-speed chain be more or less likely to jump off than a 7-speed chain?

Probably no difference *insert snarky comment about spending money to fix your chainline instead of making your bike colorful blah blah hipster blah blah* its more about the chainring and cog you have, the profile on ss chainrings and cogs will hold the chain better because they arn't ramped and pinned

Note my use of the word "perforce." I CANNOT "fix" the chainline, for reasons I needn't go into here. The question is really whether I'll get better results from a SS or shifter chain.

The color question focuses the search on certain items, but if I was convinced I had to use a shifter chain because the chainline isn't straight, I'd go with a black or silver chain if I couldn't find the colors.

You can get away with non-perfect chainlines. But then if the chain is bent enough, you are gonna have chains keep derailing. 1/8 chains are stiffer, and so derail into the bend. Chains for geared bikes can flex a bit, but that means it's gonna flex out of line and thus derail. (Stiffness can be a nice thing, you see?)

Throw on that chain as 610HX is one of the most famous chains. Ride awhile and see if if your drive-train bust. But keep in mind you can derail at any time. Also keep in mind, you could be mistaken, your chainline may be straight enough to get away with it just like with mine.

Not to bring up a sore subject, but why can't you fix it?

worse case scenario is that you'd have to get a different length BB spindle, correct?

Did you buy some expensive BB without measuring? or is it some funky set up where you can't get the parts you need?

Yeah, I normally avoid plastic frisbees on the spokes, but I'm definitely going to dig one out and protect the wheel in this case. I like building wheels, but I don't like rebuilding wheels often.

Good, you can build a wheel. Then you can re-dish and move some axle-spacers around. You should be done within one hour. Pretty easy.

Whatever I do, the chainline is going to be off by at least half the thickness of the freewheel. That (and my other thread) is a hint...

But it's a good point that I should get everything spaced as well as I can BEFORE I lace the wheel. The rim, hub and spokes are the only parts I have in hand yet, but luckily I procrastinate, so I haven't rushed to assemble them.
