Evening all,

I just picked up a mint wheelset. Campagnolo Shamal HPW, with an 8-speed Campy freehub body. Dirt cheap too.

I am wanting to run 10-speed Shimano/SRAM on the intended build.

What are my options?
-does anyone make a conversion cassette for the lonely orphan that is Campy 8-speed?
-is there a way of just swapping the freehub body, perhaps?
-do I need to relace the wheel with a Shimano freehub?

Should I just get a jtek converter & run it 8-speed?

Thanks all for any advice.

Barchettaman

It looks like Highpath may sell me the correct spacers. Does anyone have any experience with this uk company?

Drew Eckhardt 

No. Campagnolo 8 speed splines are shallower than 9/10/11 and won't accept a new conversion cassette.

Perhaps.

Campagnolo didn't start making hyperglide conversion freehubs for their wheels until after they'd moved the high-end wheels to over-sized aluminum axles, although with a bearing swap you might be able to make something work (maybe a freehub for the lower end steel axle hubs).

Barchettaman

Thanks Drew.
I´m searching the Interwebs but if anything there is too much info, it´s hard to get a specific answer amongst the myriad questions regarding shimano/campy compatabilty.
Cheers

Just a thought, I wonder if it would be possible to grind at some of the splines on the current freehub body to get the Shimano/SRAM cassette to fit. If it's steel it might be worth a try. I wonder how "close" the two spine patterns are, and if the Campy 8S freehub body is wide enough for a 10S Shimano cassette.

I think the old Shamal wheels look awesome, but I always dismissed them as being unusable (for me) because I don't have anything with a Campy drivetrain.

Barchettaman

Don´t think that´s going to work. I fear it would mangle the cassette or freehub body.
It looks like a Corima freehub for Shimano might screw on. I have asked a few online distributors and will see who responds.

Let´s hope it works as I´m mega keen on the Shamals.

Highpath have stopped trading. Marchisio may still make cassettes for 8 speed. Miche did an 8 speed last time I checked but this is all 8 speed sprockets for an 8 speed system.
I retired my Campy 8 speed due to the difficulty of sourcing spares.

There are some freehubs which fit some Campagnolo wheels and convert to Shimano type splines.

Yep, looks like freehub replacement is the way to go. I just need to be sure it will fit the older bell shaped Campy hub.

Drew Eckhardt 

Nope.

That's setup for a 2007+ Campagnolo/Fulcrum hub with the over-sized aluminum axle.

The original poster's hub is still derived from the C-Record forging. While the sexiest hub shape ever, it uses a conventional 10mm steel axle with matching smaller freehub bearing inside diameter which complicates things.

A bearing swap is a possibility to mate new freehub to old hub, although I don't know if that would be enough (for example - the locating shoulder on the axle could be longer or shorter and necessitate different spacing between inner and outer bearings).

Here are a few spares catalog illustrations:

1999+ over-sized axle (there are slight differences for 2007 and newer). I have one of these (1999-2006 Record).

Campagnolo branded freehubs with Shimano splines were available for this design:
Part WH-KX890 fits 2007+ variants
WH-KX1 (Record) and WH-KX2 (Chorus) were built for 1999-2006

Some grinding is required to mate some freehub/axle combinations. Supposedly new freehubs need some grinding to go on old axles but the swap works as-is the other way.



Conventional axle as in the original poster's hub. Athena and below used a different axle and drive side bearing than Chorus and above although I haven't a clue how that affects free hub interchange. I have a couple of these (1996 Chorus with 1997 Record freehubs to update from 8 cogs to 9/10 - that may be an option in conjunction with a Marchisio cassette with Shimano thickness Campagnolo splined spacers). Campagnolo support for Hyperglide post-dates these hubs.



Cartridge bearing design used on less expensive Campagnolo and Fulcrum hubs. I'd expect the hollow axle have larger diameter at least on the non-drive side than the conventional design but have never seen one in person and measured.

Part WH-KX3 is a Shimano splined freehub for this hub design.

Barchettaman

Wow Drew, many thanks for the info there.
Very much appreciated.

In the event that a swap to a Shimano-splined freehub isn't possible, then we're looking at a 9/10 speed Campy freehub swap, and a conversion cassette or Jtek Shiftmate on a Campy cassette, then?

Drew, can you have a look at this Corima freehub replacement - is it too modern a design for the 8-speed update?

Thanks in advance!

I´ve just had a thought.
I have an early 9-speed Campagnolo freehub on a beaten up wheel in the parts bin.
Maybe I could transplant that over and use some kind of conversion cassette on the 9-speed freehub, with Shimano spacing?

Barchettaman

OK, here´s the plan.

-swap out the 8-speed Campy freehub on the Shamal for the 9-speed Campy freehub in the parts bin.
-order a bunch of custom spacers from Chris at Highpath in Wales
-run 9-speed cassette with 10-speed shimano spacing. Obviously I´ll lose a gear, but as the crankset is a triple I shouldn´t miss it too much.

What could possibly go wrong? Apart from the 9 speed hub not fitting on the Shamal, of course? And my general mechanical ineptitude?

Campy 9/10/11 freehub bodies are online. I did a set of Chorus hubs and they work great. They used the standard small dia steel axle though. I'm sure you can convert them to use a Campy cassette. As for Shimano, Drew is correct. Campy didn't make a Shimano freehub in the early days.

Road Fan

I'm not sure if there's been a clear answer to this one: Can you swap a Campy 10 speed freehub body onto a hub originally made for Campy 8-speed? If so, I have two 8speed orphans whose careers will become much longer.

Kimmo

How many spokes are those Shamals? Are they the crazy 12-spokes? If so, you can probably lace the rear up to a 36 or 24h Shimano hub, problem solved. The wheel will be stronger too (as long as the hub flanges can handle the tension) due to the better flange spacing.

Drew Eckhardt 

Sometimes.

1997-1998 9 speed Record and Chorus freehubs interchange with their 8 speed predecessors. I installed a couple of Record Titanium 9 speed freehubs on my 1996 Chorus hubs after Campagnolo discontinued my favorite 8 speed cassette and before the New Old Stock supply dried up.

1997-1999 9 Speed Athena/Veloce interchange with their 8 speed counter parts as well as older Mirage hubs. An axle swap might be needed to swap for Record/Chorus - that went with the different freehub, along with a different drive side bearing although the 1996 hubs paired the Record bearing with the Athena axle + freehub. I've never tried that.

Everything below Daytona level in 2000 uses the cartridge bearing design previously used for 1997 and newer Mirage/Avanti. Those should interchange with each other. You might need a bearing change to use them with a higher level hub. I've never tried that combination either.

The 1999+ over-sized design definitely won't interchange. I have one of those and the bearing ID is much larger. You might be able to swap bearings and spacers to use a conventional axle, although the bearings were never intended to be replaceable and people do things like drilling a hole so they can compress the retaining ring.

Drew Eckhardt 

That won't mate to a Campagnolo hub. Campagnolo freehubs have exposed pawls which engage ramps in the hub and are secured with a nut on the axle. Those seem to have the freewheel mechanism built in like a Shimano freehub and have threads where Campagnolo pawls would be.

Presumably they're built for Corima branded wheels.

Drew Eckhardt 

Re-spacing a Campagnolo 10 speed cassette to Shimano dimensions would work and may be more future proof (Campagnolo discontinued all but 3 8 cog combinations shortly after the 9 speed introduction, and we've since moved to 11 cogs).

Current production Veloce are all loose cogs and Centaur (apart from the 14-23 which is all loose) only has the final two on a carrier.

The right 9 speed freehub will definitely interchange although you might need an additional washer on the drive side for the chain to clear your drop out when on the small cog (the 9 speed freehub is 1mm wider).

::UPDATE::

The seller misdescribed the wheelset. It already has a Shimano 8/9/10 freehub.

Happy days!

Kimmo

What, like I suggested doing?

Barchettaman

Nope - a previous owner swapped in a Shimano cassette body. I'll post pics later.

Kimmo

Maybe I missed something, but didn't everyone above concur that there wasn't a part to do the job?

Perhaps you're the beneficiary of a seriously cool bit of kludging

I'm still wondering if these are the wild 12 spoke Shamals...

Barchettaman

16 spoke Shamals front & rear. No way I was going with the 12 spoke ones with my, ahem, muscular figure.....

Barchettaman

I got the impression that a freehub swap *used to be* possible, but the parts were no longer readily available. Maybe mine was swapped way back when.In any case, I now also have a barely used 8-speed Shimano cassette too ready for my commuter which runs a 2x8 Shimano set up!

Kimmo

Sweet!
