I agreed to replace the 5 speed cassette on my brother's old bike with a 6 speed which is branded Shimano, product of Japan.
I assumed it had a Uniglide style cassette fitted and when I got the bike I found it wasn't.
It is a style of hub I've not seen before.
It is marked as Shimano D C on the hub body which has a small oil hole.
The cassette fits on what looks like a splined drive and the freewheel is inside the cassette.
I had to remove the axle to get the cassette off.
Anyone got ideas what I've got and more importantly can I get at least a 6 speed cassette for it?
