FORMULA and the world CONTENTS FORMULA COMPONENTS CENTER At Formula, we design and manufacture hubs, rims, and skewers for many high profile clients in the industry around the globe. Since the establishment in 1994, we continue to innovate with products that are crafted with the most precision and dedicated research for perfection to achieve our one and only goal: Quality With Heart. We offer wide range of products to satisfy every possible need of customers because we truly believe that high quality components make high end bicycles, which in turn gives consumers a high quality ride. Our mission is not to offer mass production with low prices, but to expand quality to every bicycle with a reasonable value as we always have. Hub is the heart of the wheel, which is one of the most important aspects to a quality and durable ride. At Formula, we begin with obssession designing strong and long-lasting hubs that are easy to maintain, even free of replacement. The manufacturing technology advances exponentially, and to stay cutting edge, our team is dedicated to look ahead and continue to upgrade equipments and technology to utilise material and techniques for the best possible result. Because of this dedication, Formula components are industry renowned for quality, reliability, and affordability.

Water resistance is not only concerned with resisting water entering the hub, but also with the friction and elasticity of the hub. Our labyrinth design is created with this in mind, and is the most reliable design for water resistance. For instance, you can feel free to wash your bike by air spray. Angular Drill Welding Rim Carbon Fiber Composite Internal Cam Design Center Lock This technique provides multiple angl machining, no matter on QR levers, hub shells or rims. Labyrinth Design for Non-Drive Side For all 2 seal bearings or higher level hubs, we machining both side of bearing seat at same time to make sure both centers stay on the same line. InteriorWater Seal Design for Drive Side Grease Spec and Location A good water resistant design is not just about the grease and the seal. Stopping water from entering the freehub is the most important thing, so we’ve designed a special interior water seal. The seal can be permanently fitted into the correct position to achieve effective water resistance. The importance of choosing the right grease specification for a hub which requires: various temperature resistance, water resistance, dirt resistance, smooth rotation after both static and dynamic circumstance, wear resistance, and extending lifespan.

Brake rotor is still in position even after several times installing and removing. Special design of lever mechanism allows users to engage and lock-in the wheel when it is in open position. When it is in close position, the lever can also be free rotated to any angle; ease of adjustment for the users.
