This mod can be performed on many different type of DT Swiss hubs. Also many OEM hubs use DT Swiss hub internals, for example the ones shown in the picture are in fact Giant OEM hubs. The 32T ratchet basically speeds up the hub pickup. In standard form,  it is something like 15 degrees before the hub engages. This modification reduces the pickup to a rapid 6 or 7 degrees. A very easy and cheap way to transform your bikes acceleration 🙂
