Converting Campy 9/10sp to 8sp. Does it work?

[Bob Lau]

Hi, I have an old Campy 8 speed Exa drive cassette and recently heard a rubbing sound while the
wheel was spinning. I took apart the rear hub for maintenance and found a half inch area of the
bearing raceway was badly pitted. It's only a matter of time before this becomes unrideable so I was
thinking of buying a new Campy 10 speed rear hub and converting it to an 8 speed. I read that the
trick was to buy a spacer kit to convert it to 8 speed and then buy a 9 speed cassette, remove the
last cog and put in the new modified 8 speed spacers. This will lessen the cost of my upgrade to a
10 speed system in the future. Has anyone tried this? I'll hoping that the modified system will
shift as well as the original setup.

My other options are to buy a NOS 8 speed hub or just buy the rear axial and some new bearings.

TIA, Bob Lau

I'll give you another option. I'll sell you a rear wheel, Veloce x Mavic Open Pro x 32 holes with
~400 miles for $105 plus shipping. If you want the matching front, $155 for the set, shipped.

There are a lot of ways you could fix this...

One way would be to buy a 9/10 speed rear wheel, put a 9-speed cassette and chain on it, and
upgrade your shifter to 9. You do not need to change the rear derailleur to do this. If you have
8-speed ergo levers you can convert them to 9 for a minimal cost in parts, assuming you can do the
labor yourself.

Another would be to get a 9s Veloce cassette (you need one where all cogs are individual) and use a
spacer kit to turn it into an 8s cassette as you mentioned. Wheels Manufacturing makes a spacer kit
for this purpose called SHIFT-8 which you should be able to order from any bike shop. Campy makes a
13-28 9-speed Veloce cassette which you could turn into an 8-speed 13-25.

The spacer kits are rather expensive which is why I would be considering a shift lever overhaul to
turn it into 9s, plus if you want a lighter cassette than Veloce, you would have the option of 9s
Chorus if you convert the shifter to 9.

I think I'll go with the conversion to 9 speed and do a change on the shifters to accomodate the the
9 speed cassette. Do you know where I can find data on this?

Or buy a loose Veloce 9s cogset, take out a cog and use black Campagnolo 8s spacers, just
did this...

See above and you need to convert the lever to 8s with EC-RE-060-8s disc, all else will work fine,
even an older rear der...

That bearing on the interior of the hub is available from us...taps off...

I know someone who does this. But why? It is a small matter to convert the shifters to 9 or 10
speed. Since you have to replace the hub anyway, get a 9/10 speed hub, and a shift-disk. That way
you don't have to spend the same money for a spacer kit to be able to use 8-speed that you would to
convert the shifter to 9. I converted my shifter to 9 speed for $35 for a part from Peter Chisolm.

8 speed cassettes will be as scarce as hen's teeth in a couple years. Bad idea.
