Does This Hub Take Hg Cassettes
15 Mar 2017
Hi I have a 1990s FH-HG50 Hub, with a 7 speed HG cassette. Is this the correct replacement part. Photo looks like it will take HG cassette, but not 100% clear.

This freehub was produced in the cross over period so it is actually compatible with both UG cassettes as well as HG cassettes.

What Tools To Remove The Cassette And The Freewheel?
21 Feb 2017
I have a old FH-HG50 and I would disassemble the cassette and the freewheel.

I will buy you the item 6384 but I would like to know what tools you buy to disassemble the cassette and the freewheel.

Sorry for my english, i'm french.


You will need a cassette tool which are SJSC part number 871 and you will also need a standard 10mm allen key for removal of the freehub body.

Broken Uniglide Freehub On My Shimano 600 Rear Hub
09 Jan 2016
I have broken the dust cap on my Uniglide freehub whilst trying to service and regrease the bearings. Is it possible to fit a replacement Uniglide / Hyperglide dual compatible freehub like the 30H 9801 to give me option to have either uniglide or hyperglide gearing. I am renovating a steel racer for Eroica and i am not sure if i will be eligible to enter the event if i dont have Uniglide gearing ..

This freehub is listed as only being compatible with the HG-50 hub so we have never tested with any other hubs so do no know if it is compatible with any other models I'm afraid.
