CampI 9spd spacing on shimano hub? Spacer kit?
 

I tried searching for this earlier and got dizzy. Some key word sets brought up too many answers som none at all. Anyway here goes...

I just purchased a great set of wheels and fabulous hubs for shimano 8+ speed. Is there a spacer kit that I could use to out these hubs on a Campi 9spd bike?

I don't want to get into a shiftmate or other bike modifications as I would like to about to use as say a spare so they be going on any one of 3 CampI equipped bikes.

Thanks for the help :)

Go to the "Wheels Manufacturing" web site. They make conversion cassettes for what you need.
The problem with a spacer kit is that you will need all individual cogs with Shimano splines. By the time you find all of the parts you could have bought a Wheels Manufacturing conversion cassette.

Edit: They don't seem to advertize 9-speed cassettes now but I think they could take care of you.

Shimano 9s spacing is 4.35mm and Campy 9s spacing is 4.55mm; if you have an individual cog cassette for it, you could prolly find a way to make your spacers 0.2mm thinner...

Couldn't I just go begging for some shimano spacers?

Many people are happy enough running unmodified Shimano 9 speed cassette. The error is an over-shift not an under-shift so reaching the big cog won't be a problem.

The error will be 0.8mm off arriving at the big cog and 0.6mm at the second smallest (with the limit screw providing perfect alignment on the small cog).

If you want it to run perfectly -

Wheels Manufacturing will convert an Ultegra or Dura-Ace 9 speed cassette for Campagnolo 9 or 10 speed use with perfect spacing. A couple years ago it was $50 + shipping.

The cassette must have the final cogs on a carrier (the Campagnolo 9/10/11 freehub body is wider than the Shimano 8/9/10, so they machine the final carrier so it can hang of the end) so they can't convert a 13-23 where the 23 is loose.

The 10 speed conversion requires a 12 starting cog and ends up with an 11.

Well, the cogs aren't the same thickness, so there's that... but I just realised I had it arse about, and you want the Campy spacing on Shimano.

- So, you just need to make your spacers 0.2mm thicker, which is actually pretty easy.

Pop a couple of layers of duct tape on the side of each spacer, then trim off the excess with an exacto knife or something (scissors work well around the outside). Electrician's tape and duct tape is pretty close to 0.1mm thick.

The best I can think of is 10 speed Shimano sprockets with 8 speed Shimano spacers.

This comes in slightly over - 4.6mm instead of 4.55mm, so the cassette will be 0.4mm too long. A single 9-speed Shimano spacer somewhere in there bring it down to 0.04mm too long.

Highpath in the UK will sell you the exact spacer kit you require.

Best of luck!

Hi Everyone. Thanks for all the info. In a PM someone suggested that Ambrosio might have something but there is more on 10spd swapps than 9. I found a place in the UK can make on for about 100pounds which I think is around $180ish and not really worth it. Wheels manufacturing can do it for about $130 but for something to have 'just if I want to' that is too much.

Don't shimano 10spd come on that carrier so you couldn't put them on freehub one by one right? I may investigate Barchetaman and Mr. Snuffleupagus ideas and see what I can figure out.

Just incase curiosity has gotten the best of you, the hubs/wheels in question are these, Ticino hubs from Electra

BBB cassettes have individual sprockets and spacers, but I don´t know if their individual thickness matches Shimano sprockets & spacers.

Maybe ask them on Facebook:

Shoot Chris at Highpath Engineering an email if you haven´t already. He will know what the options are and his shipping worldwide is only 4 pounds. I really recommend you contact him - when I was trying to attempt something similar he was really helpful.

I did what you are asking about with Shimano to Campy 10 speeds conversion using Miche cogs; should also work with 9 speeds.http://vintagecampagnoloforum.blogsp...-cassette.html. The individual cassettes cogs http://www.universalcycles.com/shopp...?category=1569 cost much more than a pre-built cassette; http://www.universalcycles.com/shopp...&category=2620. Then you buy the Campy 9 speed spacers.. http://www.universalcycles.com/shopp...3&category=503 (remember you only need 8); also the spacers work with the specific width of the cogs; check out my blog for some specifics..BTW, you may want to replace the final position 9 speed cogs with a 10 speed, as it is offset toward the hub and would give you more space on the Shimano hub shell, which is shorter than a Campy and give you more room at the end for the lock ring

Ambrosio (UK) sells 10 speed versions, but I don't see 9 speed on their site. They might have in years past - maybe find some old stock.

Yes, I saw those Ambrosio 10speed conversion cassettes after I was done fooling around with a Shimano, Campy conversion. They look good and at a good price; too bad for the OP that they are only 10 speed. http://www.probikekit.com/us/ambrosi...-10-speed.html

What's wrong with sticky tape? Too quick and dirty?

No. The cogs built on carriers have no center sections with splines. The splines are on the carrier. If you take them apart they are worthless.
Wheels Manufacturing still sounds like your best bet. It may sound expensive but remember if you buy their conversion cassette, that's one less cassette you'll need to buy somewhere else.

I run a sram 9 speed cassette on a bike with campy 9 speed (second generation) shifters and derailleurs. I have friends that run this same setup with the first generation ergos. It shifts better than the bike I have set up with 6500/7700 parts. It works. Well. Mr. Jet Sanchez has run this before as well, he can back me up on this.

I also picked up a NOS 13-26 mavic cassette with swappable spacers for both shimano and campy shifting, but I haven't mounted it yet. It's not ramped, and it's still NOS so I've been holding out for some reason.

You don't mention vintage/speeds of your Campy stuff. If it's nine speed, simply try getting a Shimano 9-speed cassette, stick it on the bike, and go ride. The spacing is close enough that if you match speeds at 9, it'll usually work.

See http://www.ctc.org.uk/cyclists-libra...gears/shimergo for details.

Has anyone else tried the tape trick?

Hello?

Seems like a good plan to me. I'd use the duct tape (or something equally 1.5" wide- masking tape?), because you can cover the entire spacer with one contiguous piece. With electrical tape, you'd have to use more than one and risk overlapping. I'm having trouble believing that duct tape and electrical tape are the same thickness though.

They aren't. I just miked a piece of 3M Duct tape and a piece of no-name vinyl electrical tape:

Duct tape = 0.0090" (0.22mm)
Vinyl Electrical Tape = 0.0065" (0.165 mm)

So the duct tape is 33% thicker.

Don't we find out the weirdest things on this forum? :lol:

I'm not a expert but I have made a couple off these work you will need 3 1mm Shimano Dura Ace type spacers good luck finding them at a cheap price last I checked they are $5 a piece on ebay.

The other day I came across a Miche 9 speed cassette on eBay that was Shimano pattern but had both Shimano and Campy spacers. Dig a little- it wasn't all that expensive.

Mavic made this type of cassette as well. I think I got my NOS one for like $30 all told.


It's this kind of stuff that keeps me coming back.

Hi Guys thanks for all the advice and I will certainly try some of out. Your not going to believe this but I realized something just as I either drifted off to sleep or woke up this morning, maybe I dreamt about it.

OK the bike these fabulous hubs are going on is currently mostly Campi but with a DA Integrated 8 RD and 8spd DA SIS shifters. However the rear wheel in the bike right now is a......Campi hub with an 8spd cassette! I got so caught up in worring about how to make these new hubs (soon to be wheels) work on my other bikes I forgot I will be taking a perfectly good set of wheels off this bike can take a Campi 9spd cassette. I will have to triple check this of course but I am certain these hubs will work on atleast some of my 9spd bikes.

OY!!! I am such a idiot at times. :(

pdlamb; 2 bikes are Record one with Ti silver shifters from '97ish, and the other carbon shifters from '99 (but could be '00 I can't remember for sure) The third is I think Athena but I have no idea what year/generation.

Nope.

With the move to 9 cogs Campagnolo changed to deeper splines (to allow alloy freehub bodies which don't indent) and made the freehub a bit wider.

That means you can't put a 9-speed cassette on an 8 speed hub.

Compatible 9 speed freehubs exist but getting one may require buying an old 9 speed hub, swapping, and selling the left over 8 speed hub which results.

( I upgraded my 1996 Chorus 8 speed hubs to 9 cogs after Campagnolo discontinued my favorite 8 cog cassette )

Well then I still at least have spare wheels for the bike the bike the Ticino hubs are destine for.
