The cassette has been modified by TNC. The last sprocket unit has been turned down by 2 mm. This allows it to be fitted to a 10-speed freehub body. The ultimate solution for wheelsets where conversion to an 11-speed freehub is not possible.

The 10-speed freehub body must have a minimum insertion depth of 35 mm. 11-speed freehub bodies have an insertion depth of 37 mm.

To reduce weight and achieve greater torsional stiffness, the three largest sprockets are riveted to an aluminium spider. A new tooth design further improves the already excellent shifting performance of the previous model and ensures extremely quiet chain operation on the teeth
