Brian Kachinsky described his signature GT Globetrotter frame as "a combination of everything I love for a stable, strong and comfortable frame." You can see a bunch of detail photos of Brain's current prototype frame as well as a prototype GT top load stem and grips, and the rest of his bike setup as well.

What were some key features for you when designing your signature frame? And what are the specs?
Having ridden so many different frame dimensions over the years I have found what I like best. This frame is a combination of everything I love for a stable, strong and comfortable frame while also integrating some newer features that I have come to enjoy. The back end is the perfect balance between stability and pop. It also has a 75.5 degree headtube, which makes it responsive. The current color I have is a trans copper, which was a gamble, but came out amazing. It ended up being a better color than I imagined. It will also be available in a couple other colors. The 9.06" standover height is also something that feels very comfortable and allows it took and feel the way I wanted.
When will they be available?
I am still testing the prototype to make sure everything is on point, but I'm hoping we can have some production versions later this year. I want to make sure everything is perfect before we release it, but so far so good!
And your stem… what are the features on that?
The stem is called the "El" which is the nickname for the elevated CTA trains that run through Chicago. This stem is a top load that's a bit taller than most stems out there so you can run less spacers, but still feel like you aren't hunched over when you're riding. We also made the newer prototype a bit wider to provide more clamping space on the bars to avoid slipping. It's strong, solid and still has a classic top load look. I love it.
Your frame comes with integrated chain tensioners, but you aren't you using them. Why not?
I might use the tensioners in the future, but I have never had too much of a problem with my wheel moving so I usually leave them out. I like having the option of them in case other riders prefer tensioners. It's nice to know that if I have a problem with my wheel slipping I can thread those in to take care of the problem. I'm usually good about keeping my pegs nice and tight to avoid it though.
How long have you been on the Original 4-piece and what are your thoughts?
This is one of the things I'm most excited about on my bike. I made the switch to the GT 4pc in the middle of last year and immediately loved them. I like the look and feel. We have gone through some prototypes to make sure they are perfect before we put them out there, but everyone who has ridden my bike immediately became a fan of them. They will come in two sizes and a couple different colors to suit people's preferences. These updated versions of the original GT 4 pc bars feel new, but also have that classic nostalgic look. I'm excited for them to be available this year.
You had plastic pegs on when we shot your bike, but do you still travel with an arsenal of eight?
Yeah, the mantra of "use the right too for the right job" doesn't just stop at the work bench. I travel with a set of four plastics and a set of four steel pegs just in case I come across something that might be better for either style of peg. For rough grinds or steel rails I still prefer metal, but obviously plastics are better for riding plaza spots, smooth ledges, aluminum rails, etc. I also always have wax on deck in case that's needed to get the job done. Carrying that many pegs seems silly, but I just always want to be prepared. It leaves you with no excuses to why you can't get something done.
What are some preferences for your bike set up? What makes it your ride?
I recently have been cutting my bars down to 27" wide. The GT bars come stock at about 29" wide, but I like a smaller width for barspins. I wouldn't want them much more narrow than 27", but I think that's a perfect width for me. They still feel wide enough, but aren't sluggish when you spin them. I usually run my bars just a tiny bit forward from the fork. Having my forks straight up and down like this allow for an easy pull-up, but also don't make me feel too cramped.
What parts do you change out the most often and why?
I change grips quite often and peg sleeves on plastic pegs. I grind a lot so having a couple extra plastic sleeves along with me helps a lot. Plastic hub guards need changing sometimes, but I usually ride those until the very end of their life. Tires and tubes are also things that wear out from time to time, but that just depends on luck usually. I do rotate my tires before replacing them since my back tire always wears out before my front does. Rotating them helps them wear correctly but saves me from having to get a new set.
What are you most particular about on your bike?
You know that sound a basketball makes when you bounce it on the ground? I like my bike to make the same sound. I love when everything is tight, quiet and no rattling. This means I keep everything pretty tight including my chain, headset, spokes, etc. I don't do many crankflips these days, but if I start to do those again I might have to loosen up my chain, but for now I like it snug. I also like everything on my bike to be a 6mm Allen key or 17mm socket. I can fix almost everything on my bike with minimal tools and I love that simplicity.
I'm also particular about shoes I ride in. I like Vans TNT, Crocketts, Old Skools, Chukka Mids, Half Cabs and any other Vans shoe that's grippy and has protection while also being able to feel your pedal. The waffle sole and the pedal pins go together like PB&J.
Last but not lease I like to be the only one who works on my bike. After many years of working at a bike shop and working on my own bikes I just know how I like everything to run. I keep it clean, tight and ready for the inevitable abuse I'm going to put it through.
