Shimano 6401/6402 compatibility

Rossmthomas · Sep 16, 2019

Hi,

I have a tricolour 6402 8 speed rear hub which the bearing cups and cones are knackered, however I have a 6401 with good cups and cones etc.

Are the bodies interchangeable? I want an 8 speed hub, can I put the 8 speed cassette body on the 6401 hub body?

Does anyone know if the bodies are the same?

Yep no difference between the hub bodies so your good to go

There is a difference between the I believe, there were 3 types. A UG or a UG/HG or a HG only.

The difference is in how the cassettes fix also. Also not sure but there might be a difference between the one used for a 126mm 7 speed compared to a 130mm 8 speed version.

Not between the hub bodies I've done enough swaps to know

Actually you are talking about the freehub body and not the hub body and there is a difference between free hub bodies

I was asking if the actual hub bodies on 6401/6402 are compatible, they’re both UG/HG cassette comparable. I know about the different cassette freewheel bodies, that’s not what I’m asking.

I found replacement 6402 hubs anyway so doesn’t matter.
