Our 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.
