What are the differences between the CSL Universal Hub (V1) and CSL Universal Hub V2?

The CSL Universal Hub V2 features several improvements over the V1. In addition to minor visual updates to the buttons, the V2 includes additional metal reinforcements, increasing overall stiffness by up to 23%. The design of the shifter paddles has also been revised for improved performance and feel.

It is also important to note that both the CSL Universal Hub V2 and V1 can support the full torque output of compatible wheel bases. This makes both versions part of the CSL ecosystem that allows full torque capability.
