Hub gear comparison chart




This site was born out of my frustration while trying to find information for myself. It should be sufficient to select a hub gear and build it into a wheel.
Everything in this table is taken directly from the manufacturers' web sites.

[1] Speedhub chainline 54mm but 58mm when using a 13T sprocket.
[2] Official site (erroneously?) says that the hub with the wider OLN has the narrower flange spacing.
[3] Many variations depending upon sprocket diameter, thickness, dish and orientation.
