Box Two 20mm Rear Hubs

All Box hubs that with axle diameters of 15mm and up are engineered and crafted using our Oversized Technology. For steering stiffness we follow the load paths down the handlebars, through the stem, headset, and eventually to the fork-to-hub interface. To transfer as much of that load from fork to axle we’ve shaped the dropout for substantially more capture of the now oversized 20mm axle. It's the same fundamentals at the rear for pedaling stiffness where we also deploy more substantial diameters to inhibit axle deflection. On both ends the added surface area begs for upsized bearings and consequently we are gifted with materially more contact surface. You’ll put more power to the ground out back and up front you’ll feel in control.When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.

Key differences: The Box Two line optimizes material distribution via a hub shell forging process. Aluminum is engineered away from low stress areas and used to reinforce intersections. In this use case we prioritize stoutness over ultimate mass because power delivery and control trump any benefits that might come from shaving a gram from interfaces.
