Chub's concept is based on fundamental engineering principles to answer the question of how to build a more stable impeller by changing the geometry and structure of the hub. Thus Chub presents a fast expanding product line of fully adjustable hubs. All Chub hubs have the oversized carbon hub bodies with oversized flanges in common. The result of this construction method is a lower spoke load and hub turn with an improved spoke angle. In addition, the oversize axles ensure increased stiffness and durability.
