Features & Functionality

Strong, precise, durable, & functional, components, for the way you ride


We design and build our components from steel, alloy, and composites, to achieve the greatest strength to weight ratio for each application. We then test every component to failure mechanically, and on the bike, before releasing them to the market.


We use advanced Computer Aided Design (CAD) to develop all of our components. We then utilize Finite Element Analysis (FEA) to determine the optimum volumes and shapes of each part. Finally we utilize precision CNC machining on the forging dies and molds used to form each part. This results in components that fit together with extreme precision.


Finally, we utilize a variety of heat treatments, surface treatment and surface hardening techniques and coatings, to achieve long life and wear resistance in each part and components. This means that our components run smoother and last longer than the competition.


Our components are feature packed to enhance your riding experience. Our shifters move the derailleur precisely with each shift for repeatable accuracy, even after many miles in the dirt. Our chains don't fall off the largest cog when backpedaling, or the chainring during repeated hard bumps. Our derailleurs have adjustable clutch mechanisms to prevent chain slap, and our cranksets feature adjustable tension on the bottom bracket.
