Bicycle Mechanics - Converting a Crankset to a single speed

Could I convert a crankset like this

into a single speed crank for my fixed?

yes, you can.

Newbie question. When you say single fixed speed or FIXIE do you mean one crank in the front or what?

As in one sprocket front, one back. Single is a freewheel like a BMX bike, fixed is fixed gear to the rear hub and pedals turn at all times, even backwards.

Is a flip flop rear hub, 42-16.

Is it possible / smart to remove the inner ring / or outer chain ring?

You generally get a better chainline with the inner ring, but check first before deciding.

Take off the little chainring and flip the big one around so its backwards and mount it on the other side of the spider.

also yo might need to get a smaller chain ring depending on the width of your chain stays.

I like to shift the hub (respace it and redish the wheel) and then mount the chainring on the outside of the spider(I also use a narrower BB axle), for good chain line, because the chainring looks better/cleaner on the outside of the spider. But I am a slow poseur.

That's what I do also. An extra benefit of using the small ring on the outside is that it will be turned around so that the chaiin will contact the unworn surfaces of the ring. I'm glad I'm not the only slow poseur here.

I have found when converting cranks to ss/fixie I generally need to get shorter chainring bolts. Where you place the ring, in or out, depends on chainline. I usually wind up on the inside, heck, no one can tell which it is when riding.

You're not a poseur unless you act like you're fast and you're not.

And when you are working with stock track wheels it's the simplest.

i am building a single speed freeride/dirtjumping bike and i was wondering what are some good but not to expensive front and rear gears are
