I want to put a 46T crankset on my single speed road bike im building...i dont want a too hard ride and was thinking of a 17T for the back gear to move the tire...will this be ok or what size should the back gear be?

that should be fine for most areas, I'd buy a few freewheels so you can figure out what is best for you.

well i will be on flat road most of the time.

What are the handlebars called that arnt bullhorns but the other ones that are kinda like this __

drops.

your instincts are correct. it doesn't help much , but i'll take a stab at, mountain bike handlebars with BARENDS. just a guess.

i think his shape is supposed to look like this:

yes!!!! sorry haha

ok, maybe an aerobar????

to OP:

if so, technically not handlebar, but handlebar addon.

So the bike im working on has a Handlebar stem that is slanted downwards and im a taller bigger guy who wants to use this bike to help get into shape but i am affraid that it will be to foward for me if i use drop handlebars...i wanted to keep it original as much as possible but im not sure if there is a handlebar that would be good for it or not. Any ideas?

if your bike has a threadless headset and non-threaded steerer tube you may be able to remove the stem and turn it upsidedown (commonly referred to here as "flipping".) and reverse the slant. does the stem look like this?



if so, you're in luck.

the stem is one piece...it goes into the fork.

you are not in luck.

As to the gearing, that totally depends on your fitness level.

Read this, and consider yourself enlightened.

I run 46 x 17, which is a little light but great for accelerating away from stops and makes for decent climbing, easy on the knees. Drop bar all the way. If you are too streched out you might be stuck with using a simple flat bar or riser bar.
