I hate to tell you, but your "new" GT is at least ten years old!
Those shifter look kinda suspect. Maybe a different set would change the travel/shift issue. Check with the mechanics forum, it's a great resource! Interesting bars.
My hybridized MTB
I finally added bar ends. Used Bontrager Pluto. Also used Oury lock-on grips and a used bell (missing dome shaped compass)
I scratched the sticker, then I realized I could remove it. I removed all the stickers, five, I think. Now my fork looks like bathroom plumbing. A clean look.
Also added a fifteen year old used bottle cage in the worst color for this bike and a used fender. I think I finally got the saddle tilt right. Every time I thought I had it, when I tightened it down, the nose would drop. I rode for a month before I got it right (last night).
