This looked like a formidable project before.  I watched a video and it looked so simple and cheap.

First of all why go one by?

 

    1.  Its a trend; 

    2.  The bike looks simpler and less complex;  you remove the left shifter and cable and 2 to 3 chain rings

    3.  You lighten your bike by 300 to 600 grams which is substantial

Steps:

    1.  Remove your crankset from your bike.  Be sure it has 104 BCD  (bolt circle diameter - distance from one hole for the bolts to another center to center)   Most of the stock crankset has 104 bcd

    2.   Buy a  lightweight chain wheel, big small (narrow wide)  They come in various color.

They come in various sizes:  38, 36, 34, 32, and 30.  Which gearing fits you best.   (I would go for the 34 or 36  the lower chain ring on the road bike)

    3.  Remove the 3 chain ring 42, 32   24

   4.  Install the new chainring using the old bolt, installing a a thick lock washer,  wideing it a a little bit, or a thinner bolt and nut.   

If you have 42, 46, or 51 gear set all ready installed, you are ready to go  The chain may be all ready in correct length.
