The Kinfolk Track:  Where Brooklyn Culture Meets Japanese Master Builder Precision

Hand-shaped by Master Builder Shuichi Kusaka in Kansai and adorned with coveted 1980s NJS components, this isn’t just a track bike—it’s a rolling manifesto that whispers ‘Run With The Hunted’ to those who understand the obsessive pursuit of velocipedal perfection.

Frame Geometry & Construction: The Kusaka Method

When an email from John Buellens lands in your inbox, you know something special is about to unfold. Furthermore, this particular Kinfolk track frame represents the pinnacle of Japanese frame building tradition. Master Builder Shuichi Kusaka shapes each tube in his Kansai workshop with meticulous attention to track-specific geometry. The frame embodies aggressive angles designed for the velodrome, yet maintains the versatility that street riders demand.

Additionally, the construction process follows time-honored Japanese brazing techniques passed down through generations. The steel tubing selection reflects decades of refinement, creating a perfect balance between stiffness and compliance. Moreover, each lug joint showcases the precision that distinguishes hand-built frames from mass production. The bottom bracket shell sits lower than typical road frames, while the head tube angle remains steep for instantaneous steering response.

NJS Heritage Components: The Suntour Superbe Ensemble

Subsequently, the component selection transforms this frame into a rolling time capsule of 1980s Japanese track racing excellence. Bartek Kolacz, who built up this particular example, specifically requested a bike centered around vintage Japanese track parts. The Suntour Superbe drivetrain represents the apex of Japanese component manufacturing from an era when precision engineering defined national pride.

Meanwhile, the rare NOS Kyokuto pedals elevate this build beyond typical restorations. These pedals, virtually impossible to find today, feature the distinctive knurled bodies that defined professional keirin racing. Furthermore, the Superbe hubs laced to Araya rims create a wheelset that combines legendary durability with period-correct aesthetics. The precision-matched components work in harmony, delivering the silent efficiency that characterized Japanese track equipment.

Nevertheless, finding these components requires dedication that borders on obsession. Each piece tells a story of Japanese cycling heritage, when track racing held cultural significance beyond sport. Therefore, this ensemble represents more than mechanical function—it preserves a moment in cycling history when Japanese craftsmanship challenged European dominance.

Master Builder Profile: Shuichi Kusaka’s Craft

Master Builder Shuichi Kusaka operates from his workshop in Kansai, where traditional Japanese craftsmanship meets modern cycling demands. His approach to frame building reflects decades of experience, combining ancient metalworking techniques with contemporary understanding of biomechanics and materials science. Subsequently, each frame emerges as both functional equipment and artistic expression.

Moreover, Kusaka’s philosophy extends beyond mere construction into the realm of cultural exchange. Working with Kinfolk Bicycles, he bridges the gap between Japanese precision and Brooklyn creativity. Additionally, his frames serve as the foundation for Kinfolk’s ethos, where the collective consciousness of creative minds spanning Tokyo and Brooklyn manifests in steel and chrome.

The master builder maintains strict quality control throughout the process, personally overseeing every braze and checking alignment multiple times. Furthermore, his reputation attracts serious cyclists who understand that hand-built frames offer something mass production cannot replicate. Nevertheless, Kusaka produces limited quantities annually, making each frame increasingly valuable as functional art.

Cockpit Configuration & Contact Points: The Nitto Touch

Consequently, the cockpit arrangement showcases Nitto’s legendary attention to detail and manufacturing excellence. The Japanese company, producing components since 1923, provides both stem and handlebars that perfectly complement the frame’s aggressive geometry. The polished aluminum finish reflects light like liquid mercury, while the precise tolerances ensure zero flex under maximum effort.

Furthermore, the Nitto stem positions the rider low and forward, optimizing power transfer for track sprinting. The handlebars feature the distinctive bend that Japanese keirin racers prefer, offering multiple hand positions despite their compact width. Meanwhile, the bar tape—likely leather or cork—provides tactile feedback essential for high-speed maneuvering.

Finally, crowning this build sits the iconic Kashimax Aero saddle, a component that instantly identifies this as serious Japanese track equipment. The narrow profile and firm padding suit the aggressive riding position, while the distinctive graphics announce its racing pedigree. Therefore, every contact point reflects purposeful selection, creating an interface between rider and machine that prioritizes performance over comfort.

The Kinfolk Philosophy: More Than Just Bicycles

Beyond the mechanical excellence lies Kinfolk’s broader cultural mission. The company operates as a collective consciousness spanning continents, with the Kinfolk Studios in Brooklyn hosting rotating DJ sets, art exhibitions, and music events. Similarly, the Kinfolk Lounge in Tokyo serves as “a mecca for international travelers, design aficionados, neighborhood regulars, and drinkers with biking problems.”

This cultural cross-pollination infuses every frame with meaning beyond transportation. The ‘Run With The Hunted’ ethos emblazoned on each frame speaks to those who pursue excellence regardless of mainstream acceptance. Moreover, owning a Kinfolk means joining a community that values craftsmanship, creativity, and authentic expression.

Subsequently, the fusion of Brooklyn street culture with Japanese precision creates something entirely new. Neither purely American nor strictly Japanese, these bikes occupy a unique space in cycling culture. Therefore, each Kinfolk track bike becomes a statement about global creativity and the universal language of quality craftsmanship.

Conclusion: The Perfect Synthesis

This Kinfolk track bike represents more than the sum of its exceptional parts. Through Master Builder Kusaka’s skilled hands and Bartek Kolacz’s thoughtful component selection, it achieves a rare harmony between form and function. The marriage of 1980s Japanese NJS components with contemporary frame building creates a machine that honors tradition while embracing modern riding demands.

Furthermore, the collaboration between Kinfolk’s creative collective and Japanese craftsmanship demonstrates how cycling transcends borders and cultures. Each detail, from the Suntour Superbe drivetrain to the Kashimax saddle, tells a story of obsessive attention to quality. Nevertheless, this bike isn’t meant for display—it’s built to be ridden hard, whether on the velodrome or city streets.

Ultimately, receiving photos of this build from John Buellens doesn’t just brighten an inbox—it reminds us why hand-built bicycles matter. In an era of mass production and planned obsolescence, the Kinfolk track bike stands as testament to enduring craftsmanship, cross-cultural collaboration, and the pursuit of two-wheeled perfection.
