MOBI > Hi-E Cassette Hub

In the early-mid 1990's, Hi-E offered a cassette hub using an axial ratchet. The design is similar to the ratchet on a Hugi hub (as of 2009 is sold under the name DT), but there are many small differences.

Hi-E cassette hubs are light, especially by standards of the day, about 195-200g. However, users reported "skipping" under load, even when new. Several observations about the hub's construction:

Note some recent (currently 2009) light hubs also use a plain bearing between cassette carrier and hub body, but also use a plastic or ceramic bushng, and also use ratchet pawls, which are substantially insensitive to radial alignment.
