Suntour rear hub freewheel and cassette compatibility

[edociamb@inwind.it]

Hello, for my retro-bike project, I bought on e-bay a 7 speed rear hub (NOS), model FH-XC02-7 and a 7 speed cassette, I think the model CS-AP00-K7 (looking at old suntour catalog). When I tried to install the cassette on freewheel, it seems this is too short for 7 speed cassette and it seems for 6 speed cassette, but as I wrote, the rear hub code is for a 7 spee cassette. Can someone help me to understand more? Do you know which length the 7speed freewheel should have?
Thanks a lot.

Are we talking freewheel here? Or a freehub / cassette.

Freehub / cassette

It's a bit after my time but is it an issue with Suntour Ultra stuff being thinner?

I discovered the issue. The free hub is for Micro Drive cassette and it is shorter than the "normal" one.

Yikes, that will be expensive to find. Out of interest, is it possible to remove the freehub and swap like on shimano RH’s?

Honestly I don't know, I hope so...

Yes, the freehub does come off. You need to put the allen key in from the non drive side, unlike shimano, as far as i can remember!

You can swap the freehub out for others. I might have one in my stash, I don't have any cassettes to test with but iirc there are measurements somewhere on here that explain the different sizes. If you are interested, I can dig out what I have and measure.

Yes, please

yes, please. Let me have the measure or a picture. Attached you can find a picture that explains the differences between MD free hubs and "normal" free hub
