This kit can be used to either upgrade or service your DT Swiss star ratchet hub. If you have a DT Swiss star ratchet hub with less engagement like 18t, this upgrade will give you24 teeth for higher engagement and a more immediate power transfer.

This is a great upgrade as higher engagement allows for an easier time getting up and over tricky, technical climbs, where even losing out on half of a crank rotation might hold you up.

If you are looking for even more engagement, check out the 36t upgrade or 54t upgrade.
