Drop Bar conversion confusion???
I ran across a picture of a hybrid bike with drop bars but what was odd about it was the shifters were placed on the inside space of the drop bars and his/her brake levers work with V brakes, how is this possible when people have been telling me I need to get a travel agent for the brake levers to work. Here is the picture I saw and a few pictures of my current progress. What shifters is this person using? I was thinking about using grip shifters for my drop bars if they can fit on at the end or bar end shifters.
Any advice would be greatly appreciated.

I'd think they Kludged on a set of thumbshifters off a mountain bike..
or some discontinued sun tour part, sun tour themselves is discontinued.
There is an adapter that goes in the back end of the handle bar, and offers a smaller tube ,
compatible at 7/8" to fit a grip shifter on there , designed by The Hub BuB bike shop in Ohio
so its named the hubBub adapter.
just putting on Bar end shifters seems simpler to me , but it's your project..

you'll either need problem solvers travel agents to use V-brakes with drop bar levers or tektro RL520.

Tektro RL520 work with linear pull/V-Brakes.
Those shifters looks like they're using Kelly Take-offs or something... I'd just get a set of bar-end shifters, or rather, I did when I did this conversion a while ago.

the difference is the amount of cable pull.
V-brakes require linear 1:1 ratio pull levers, but road levers pull less cable. I think it pulls about half as much cable.
Alternatively, you can swap the brakes for some cantilevers, but that is more expensive, as you'll need the brakes + cable hangers.

well after looking up the kelly takeoffs I decided that the bar end shifters would be a more simple choice, and the most I paid so far for this project is $10 but the $10 covered all together the brake levers, drop bar, clip pedals, beverage holder, and a cantilever brake. Thanks everyone for clearing up my confusion I really do appreciate it.

Long gone, and not compatible with anything current (unless you keep them in friction mode).
Current Grip Shifts will not work on road handlebars unless you get a Hubbub adapter: https://www.universalcycles.com/shopp...5&category=162 . The very first Grip Shifts worked on drop bars, but they are also long gone.

Kelly Take-off on the left, Suntour Command shifter on the right.
How many speeds is your Giant? What rear derailer is on it?

Those MRX's on the Trek are 7-speed so you don't want those. Look for some 8-speed Sram Attacks to go on some adaptors if you are dying to go the Gripshift route.
This is what the OG road diameter Gripshifts look like. I don't think they ever made it up to 8-speed and they'd be REALLY hard to find I imagine.

just overextend the lever past the final click, and you have access to your 7th gear
currently using suntour 6sp accushift barcons with shimano 7speed cassete, just had to file down the limiter on the shift lever...

Obscure but useful info: suntour accushift 6 speed shifters, happen to pull the same amount of cable as a shimano 7speed

In the OP's photo, that is definitely a Sun tour Command shift on the right but it is not a Kelly Take-Off on the left. I don't know what it is but it's definitely not a Kelly.

Can you get 8 speed stem shifters and set the left one to friction (if that's not the default)? Do that and you should be good to go.
Something like this:
https://www.amazon.com/Sunrace-Stem-D.../dp/B004JKI29S
Or did they ever make thumbies for 8 speed? If so, grab a couple of those and just mount them next to your brake lever. That might be what's been done in the OP picture. I went with Kelly's and like them, but their cost means they're not for everyone.

For a Kelly-like setup you'd need 2x bands, grind the unneeded boss off each one. As for indexing, since the right shifter is on the left drop and the left shifter is on the right drop you'd have to criss-cross cables (or just get used to rear shifting on the left).
So yeah, if you can get a couple of stem shifter bands with correct bosses for the shifters and some 3x8 downtube shifters then that would be one way to go. Seems like the lack of thumb clearance would be a bummer, though.

A new set of Barend shifters are the easy choice.
I'd also consider a clamp on adapter for using down tube shift levers.
Easy to install and the levers are out of the way compared to barends. Out of the way as in completely off the drop bars.

Barend shifters looks like the best option for me at the moment, plus I don't think down tube shifters are compatible with newer frames or drop bars just by sizing the down tube clamp and the width of my spacer and drop bars.
