Established in 2015. BAM SHIFTS started as a thought that came from the constant need of owner Ivan Marcinko to explore, to create art, and to bring his vision of a rad shift knob brand to life.  Based in southeast Idaho, we at BAM SHIFTS strive to provide top of the line shift knobs and accessories, carefully designed, and mostly manufactured in-house by husband and wife Ivan & Vera Marcinko. As a family owned business that started in our first small garage, we have come a long way in the past 7 years integrating unique craftsmanship with custom designs to provide amazing pieces to suit your wants and needs, we work hard to keep our quality up and always guarantee our work.



Thanks to its unique composition, bamboo is naturally designed for strength...

  • Unlike wood, bamboo has no rays or knots, allowing it to withstand more stress throughout the length of each stalk.

  • Bamboo’s sectional anatomy, both as a cane and on a microscopic fiber level, enhances its structural integrity.

  • The high silica content in bamboo fibers means the material cannot be digested by termites.

  • Bamboo contains different chemical extractives than hardwood, which make it better suited for gluing.


In structural engineering tests bamboo has been shown to have...

  • Higher tensile strength than many alloys of steel

  • Higher compressive strength than many mixtures of concrete

  • Higher strength-to-weight ratio than graphite
