Done some reading, and browsing and found a few things I'd like to get for my bike. Yes it's a week old and I've already torn it apart and gone through everything. :D

I was browsing on Amazon and saw this Aqua colored 3-piece crank set by Retrospec. What do I need to get this on my bike? It would match the color of my Jeep almost perfectly!


Also... would THESE Handlebars & THIS Stem be compatible?

I haven't been able to nail down a stem measurement, they keep saying 21.1 or 22mm.... Thanks guys!
 
This bike?

If so, crank'll be easy; that looks like a 1.125" headset, which'll be a PITA.

For the cranks, you need to remove your cranks, knock out the cups, and install one of these:

The crank itself, and a 68mm bsc-threaded bb. You'll need to figure out the length of the spindle to match your hub's chainline. If I had to guess, I'd say 110mm, but you might wanna take some measurements and consult the Retrospec site to be sure. (I feel like I've gone thru this before with another member, but i don't recall 100%....)

For the stem, well, let's confirm that it is indeed a 1.125" threaded, and then we'll see if you really feel the need to change the stem (and to what) before we whip up a shopping list, b/c there's a lot of kludges designed for skinnin' that cat...

Thanks! I measured, and it looks like the chainline is around 42mm. Retrospec doesn't have any specs on their site unfortunately... so I might have to pick that up first in order to get the correct BB right?

As far as the threaded neck goes... I'll have to get back with you on that.
 
Oh, dude, you're golden. You can run any of the 1" quill stems-- 22.2mm or you can even run 21.1 with a shim, if there's a 21.1 stem that you really like....

As for the chainline, let me see if i can't hunt down the post or PM where some other dude was going to run a Retrospec crank with a ss coaster hub.... chainline is usually around 41 or 42mm, depending on the cog....
 
I found the PM, the guy with the Retrospec crank was running a Truvativ american-to-euro adaptor and a shimano cartridge BB with a 113mm spindle; it was too far out for his bike. Judging from pics he sent me, he could've gone with a 107mm and it would've cleared, but he ultimately ended up putting the chainring on the inner position of the spider. So, here's my advice:

Get your Retrospec crank,
this adaptor: http://www.niagaracycle.com/categories/truvativ-bottom-bracket-conversion-american-to-euro (or one like it...) make sure you install it properly; one cup is for the left and the other is for the right...)
And this BB: http://www.niagaracycle.com/categories/shimano-un55-bottom-bracket-68-x-107mm-english-threading (or one like it. Just make sure it's definitely 68mm, definitely english threaded, and get cartridge bearings... and i'd go 107mm, 110mm at the most...)
If you don't have it, get this tool:
http://www.niagaracycle.com/categories/park-bbt-32-b-b-cartridge-tool
(You can turn it with a 32mm headset wrench or a big ol' adjustable.... remember, the right side is reverse-threaded....)
Get whatever 130mm BCD chainring you want, but bear in mind that if you get a considerably bigger ring, it may not clear your chainstays. Then again, it totally might--- just measure first.

Also, you're going to need different pedals--- 3 piece cranks take 9/16" pedals, and your one-piece crank takes 1/2"....
