In this article I’ve tried to round up all of the “Alt” bars I could find for easy reference. I’ve divided the article into handlebars made in the USA and those made abroad. I’ll continue to add to this article as I find more handlebars. Add a comment if you know of any bars that I’ve missed.

1. Versatility - The Alternator's adjustable swing plates allow the use of geared or singlespeed drivetrains on the same frame without chain tensioners or adaptors. It also means that when a hanger bends beyond repair, or a derailleur explodes, you can quickly and easily convert to a singlespeed drivetrain, and get yourself rolling back towards civilization (or home).

Your mileage will vary depending where you buy all the parts.
This is such a subjective question but a valid one if you are new to bicycling, racing single speed cyclocross, or going from geared to dedicated single speed.
I'll offer two approaches to resolving the "What gear should I race Single Speed Cyclocross In?" question. The first is a bit structured and the second one is a starting recommendation.
The structured option is to get a geared bicycle, go on a race course that is representative of the courses that you will be racing on, i.e. if most of the courses you race-on are hilly pick a hilly course to test this out. With the geared bicycle pick a starting gear and do a couple of laps, then adjust to an easier/harder gear. Pick the gear that you are most comfortable with knowing that you want to have a good ratio between pedaling and running.
Once you have the gearing take the front and rear gearing numbers and convert that to gear inches using a gear calculator. This will give you your gear inches and from there you can pick a front chainring and rear cog to match the gear inches your did on the geared bicycle.
The second option is to race a few races with a starting recommended gear. I recommend 42x19 gearing. Start with this, 3-4 races into the season evaluate and either get a bigger gear or a lower gear. Best of luck!
Some day this will come true. Material would be Carbon or Titanium. Chainline Adjustment via the bottom bracket or read drop-outs is the cleanest and easiest. I'm done with cables hanging all over the place, internal cable routing is the way to go.
The frame should have oval top tube for shouldering during races, dedicated single speed brake levers and single speed wheel hubs means I'm committed. A dedicated bottle opener integrated to the frame.
