11 speeds cassette compatible with 10 speeds hub

The approach

We machine the aluminum spider of the larger cluster.
The difference between a 11 and 10 free hub body is 1.85 millimeters, so we remove this distance on the cassette
Our machining process allows a perfect result and guarantee a compatibility with all hub and spokes shapes.

Furthermore, machined 11s cassettes are still usable on a 11s hub by adding the 1.85mm shim coming with all 11s wheelsets.

The process

Here is the fabrication steps, old HED Bastogne wheel with Sram eTAP.
