Race SL Hubs Spacing:148x12mm Boost making this single rim modelOur all aluminum SL Race Hubs are lighter than our previous carbon shelled Race hubs, and even more durable. We kept the same freehub internals and 6 degree engagement for great feedback and performance, but wrapped it in a lightweight, all aluminum package that'll go for many years to come without hassle.
