Mavic M10 Cassette for Camapagnolo 9 speed spacing

Greetings to the forum,

Has anyone used these cassettes in the past?? Any feedback (is spacing accurate??, is shifting nice and smooth??)
I want to use them to get Campagnolo 9 speed spacing on my Mavic Ksyriums which have a Shimano Freehub.

Option 2 is to get a Campagnolo replacement freehub + Camapgnolo Cassette (say veloce) + Mavic/campagnolo lockring.

Option 1 will cost me £60
Option 2 will cost me £90

My Campagnolo 9 speed setup is as follows if it is of any relevance (Record 9 sp shifters, Chorus 9 Sp chainset, Chorus 9 sp front mech, Chorus 10 sp rear mech).

There are some makers of Shimano splined cassettes with Campagnolo spacing. If you take some time with an internet search you should be able to find a few options. Otherwise, buy a new freehub body and convert the wheel to Campagnolo ready.

Another option is a Jtek Shiftmate to let your Campy shifters and rd work with a Shimano cassette. Look here: http://jtekengineering.com/shiftmate.php
It seems you will need a Shiftmate #1 to match these components. And, yes, Shiftmates work very well.

I have a 10 speed American Classic conversions cassette. Works fine

I have actually purchased a Mavic M10 but I have the choice to return before opening!

Why are you voting against this option?? Is it the cost, shifting performance, built quality ???
I like the fact that you get loose rings so you can play around with ratios.


There seem to be a couple of 10 speed Shimano spline/ Campagnolo spaced cassettes (ambrosio, wheels mfg, American Classic) but so far I was not able to find any 9 speed options!

Yes, shiftmate is an option I could consider but I am looking to replace my shimano cassette as well as I dislike the ratios.

I still have option 2 of getting a Campag freehub and a Veloce 9 Cassette!

Some people are happy enough running 9 speed Campagnolo drive trains with Shimano cassettes.

If not the least expensive option (assuming they still do it) is to buy an Ultegra cassette with the big cogs on a carrier (this limits your options), send it to Wheels Manufacturing with a check for $50 + $8 domestic shipping (I have no clue about foreign), and wait.

Ready made conversion cassettes often sell in the $150 range.

With cassettes being wear items you might change based on terrain you're better off not using conversion cassettes.

I'm sorry, I misunderstood. I thought the M10 referred to the freehub body. As I said there are a few Campy spaced cassettes with Shimano splines. Re-reading, I see your question is more like.

Has anybody used Mavic M10 cassettes in Campy 9s version? How were they?

I can't help you there, but suspect they're at least as good or very close to the other analogs available.

This is an old-pull/ new-pull mismatch right there. So my vote is neither Option will work quite right.

Well, I also have a Record Titanium 9 sp rear mech which used to be on this bike before the Chorus 10sp. I installed the Chorus because it had a longer cage.

It is my understanding that cable pull/ actuation is only dictated by the shifter and it is not affected by rear mech!

Shifting performance was not good with the Record 9 sp mech either.

Yes and no. Your old 9s mech is probably pre-2001, and has a B-screw on the upper body. In 2001 when they introduced 10s Campy went to the new design (no B-screw) with the adjustment via a work gear on the lower body. Unfortunately the cable pull ratios of the two generations is slightly different, so an older 9s derailleur would use a different cam (marked 9) than the new one (marked 1 (for 2001).

The difference isn't great, but it's enough to make shifting noticeably sloppier.

That's how it works with Shimano road derailleurs, but Campagnolo is different.

Shimano uses a 1.7:1 actuation ratio (except old Dura-Ace where it's 1.9:1) meaning the derailleur moves horizontally 1.7 times as far as the cable pulls.

Campagnolo used a 1.4:1 actuation ratio for 8 cogs and 9 cogs which are on a slightly wider freehub.

The large cog on 10 speed setups is dimpled or on a carrier so it can be closer to the spokes making for an even wider cassette on the 9/10/11 splines and instead of making the shift cable drums bigger to allow more pull they increased the ratio to 1.5. Late 9 speed derailleurs (with lower pivot tension adjustment) got the same treatment so Campagnolo wouldn't need to make two sets of derailleur parts and Campagnolo released corresponding index cams.

11 speed setups hang the big cog farther off the freehub end and use a slightly higher ratio.

You leave and learn :-) !!

I am not sure what you mean by "different cam (marked 9) than the new one (marked 1 (for 2001)"

cam?? cable actuation m....???

I assume there is only one Campag 9 spacing, i.e. the Campy Veloce 9 sp cassettes still in production are compatible with the pre 2001 groups??

You are correct that there is only one C9 [cassette] spacing, but the rear derailleurs/Ergo shifter used two different actuation/cable-pulls to get there. If you stick with Record and Chorus Ergo/RD it's easy - all 9s is old pull, all 10s is new pull. In the other groups it's not always so easy.

Understood !! Cheers !!

So I guess Record 9sp rear mech should go back on the bike.


What would you do with Cassette though??

Return the Mavic M10 Cassette for a refund and get a Campagnolo Splined Freehub + a Veloce 9 sp cassette??
or stick the Mavic M10 cassette on the current freehub, using the provided Campag 9 speed spacers and see what happens??

Right lever index cam which the cable wraps around.

Provided that you have the parts you can convert a round-hood 9 speed shifter to a 10 or change between actuation ratio standards



The cam (smaller diameter, the larger diameter is the ratchet which mates with the thumb lever) has an appropriate number (8, 9, 10) of notches on each of two opposing sides spaced as needed for the derailleur vintage



It engages a pair of G-shaped springs in the lever

Not true,

In 2001 they were still making 9s Record and Chorus along with the new 10s. The 9s platform in 2001 used the same derailleur as 10s (except for markings), so it needed a different cam (the inside part of the ergo lever that controls the indexing)

There are therefore 2 9s cams. The original which was marked with a 9 in a circle, and the one with the right spacing for the new derailleur, which was marked with a 1 in a circle (1 stood for 2001, or 9s in 2001, vs. old 9s).

They never made new cams for 8s to work with the new derailleurs because by 2001, they considered 8s obsolete.

As indicated in the manual page I posted 8 speed shifters are officially compatible with new ratio 9 speed derailleurs provided a 9 speed chain is used to work well with the skinnier pulleys.

The mismatch is probably OK with 8 cogs because a new derailleur with an old shifter produces an over-shift not an under-shift and the wider spacing tolerates the misalignment approaching the cassette ends.

Index cams were also available to run 8 cogs with the rounded hood levers.

There were also a few unique parts used during pointy-hood, clock spring, 9 speed transitional shifters.

My inclination would be to run the Camapgnolo freehub, since Veloce 9 speed cassettes are likely to be available for longer than Mavic M10 units and that provides a conversion path to a Campagnolo 10 cog setup.

"Clock springs" are spiral torsion springs. Internet using Campagnolo mechanics tend to use the term to describe that part.

And since we are on the ergo shifter subject :-)

I really like that Chorus 10 speed rear mech so I guess another option would be to keep it on the bike and modify my shifter with a 10 click/notches "Cam".

As Campagnolo 10 speed is a more up to date system in general the availability of both Campgnolo Cassettes and Camapgnolo re-spaced shimano Cassettes seems to be much better.
Also the Mavic M10 cassette I purchased comes with 10 speed spacers as well!

I know the instructions for upgrading are on Campyonly and parts can be ordered of the internet, the question is, can I do it on my own or will I end up messing up my ergos??!
