Shimano 600 SIS RD/6 Speed Freehub Cassette?

[Mr Weirdo]

Hello Retrobikers!

Just had meds lol

Another one of my dopey questions...

I have a Mavic SUP rear wheel with a Campagnolo freehub and its very nice but I run a Shimano 600 SIS RD with a 600 freewheel hub, etc.

Can anyone recommend a suitable cassette that would work with the 600 SIS RD? Would it have to be Campagnolo for it to work on a Camp free hub...I suspect that answer would be a yes. Any suggestions?

Many thanks

Campag freehub will only take the right cassette sprockets - so you might need to mess with the spacers.

For your derailleur/ shifter to work, you just need the right spacing between sprockets.
Shimano 6 speed is 5.5mm

So if you get some campagnolo sprockets (there's 3 different fittings natch so get the right ones) measure the thickness, deduct from 5.5, then make up some spacers.

C8 is 5.0, so 0.5mm spacers would do that.
Chicken used to sell them but probably impossible to find, so you could grind some down or find a 3d printer.

Alternately you could fit a shimano freehub body if thats available? Or swap the hub out.

Shimano shifters and rear derailleurs will shift OK over 6/7/ 8 and 10spd campagnolo cassettes / freewheel

I've never tried 9 speed though

My Pennine ran Campagnolo Shamal 8spd with the 600 'tricolour'

And to further noodle your nogin, 600 hubs with a 10spd shimano cassette and...

Wait for it

10spd campagnolo!

Thank you, thank you, no sorry, no autographs today

So, Shimano shifter and mech works with campagnolo 6/7/8 and 10spd cassette/freehubs. Sometimes you can go the other way and get away with campagnolo on shimano cassettes but you can never really do a mix of say, campagnolo shifters with shimano mechs.

Don't let anyone tell you otherwise, I have spoken. So there.

If it's a Campag freehub body then you need to check the splines: if alloy then it will take 9/10/11/12 speed. If steel then it's either a 7 or 8 speed depending on the length of the body. 7 and 8 both use 5.0mm spacing, which will work well with a Shimano 7s setup.

Probably easiest is to switch off the indexing.

Although iirc the shallow c8 splined cassettes fit on the later alloy Campag fhbs with the deeper teeth - its not ideal because the lower contact area can munch the alloy, but many have done it. Don't lend your bike to a time-triallist (but this is a good rule of thumb anyway).

If you set up shimano 6 index on the 3rd sprocket of a campag 8 cassette, and use the derailleur stop screws to get the right position on 1 and 6, then 2 and 4 will be 0.5mm out, 5 will be 1mm out, but 1 and 6 will be spot on due to the stops, so I think you will be grazing in the fertile uplands of @legrandefromage shimagnolo Country.

Innit?

Thanks everyone...better than a bedtime book...gets the old brain working...theres a hamster in there on a treadmill and he's knackered . I will of course reread a number of times, make notes and devise a plan of action!

At my age my nogin doesn't get much if any noodling so I'm very grateful

The secret is that float in the Shimano top jockey wheel. It's about 1mm either side and it usually can be persuaded to work. After a while the cables get a bit gummed up and it's a pain.

The point about 8 fitting on a 9+ speed alloy body is a good one - you might get away with it but the high chain tension with a triple will be worse, so don't try it with a triple.
