10-speed cassette for Mavic Cosmos?(6 posts)

10-speed cassette for Mavic Cosmos?DeRanger
Aug 31, 2002 9:38 AM
After some very helpful advice on groups and a couple of great links to inexpensive dealers, I've decided to go Daytona/Cantaur for the Pinarello.

I think I've run into a glitch, however. I'm considering the Mavic Cosmos wheelset, but I read someplace that the Cosmos will only handle 8- or 9-speed cassettes, which would make it incompatible with Daytona/Centaur (at least as I understand it - this is much easier with mountain bikes!).

Can the Cosmos handle a 10-speed Campy cassette? If not, is there another cassette available that would work with the Daytona/Cantaur rear der? Or is there yet another way to do this?

American Classic makes a C-10 compatable cassette splined for Shimano about $82. Wheels Manufacturing does also, about $130, check Excel. These may work, but the Mavic freehub body has a different depth that may make it difficult. These cassettes are really made to work on Shimano freehubs. Mavic hubs use Shimano splining, but their cassettes use Campy spacing, and the length of the freehub body is different than either. Sounds like a typical French solution doesn't it? Mavic makes a cassette kit that can be built 9 or 10 speed and it fits Mavic CC9 hubs (I'm not sure if Cosmos use CC9 hubs). The Mavic kits can be had from Excel for about $100.

However, if it were me, I would absolutely buy Campy Proton wheels rather than the Mavic Cosmos. Protons are the same price as Cosmos but nicer, and the assymetric rear wheel is very strong. With Protons, you just use Campy cassettes and skip the hassle. Centaur 10 speed cassettes are about $70

If you decide to go with the Cosmos then your options are as follows:

- Mavic M-10 cassette designed for shimano splines; poor design shifts poorly

- Wheels Manufacturing 10 spd cassette for shimano splines; depending on model, essentially either an Ultegra or Dura Ace cassette converted for 10 speed, shifts well but requires initial set up to do so by shimming with spacers

- American Classic 10 spd cassette, fairly new, but company has an established solid reputation, check out their website, they sell direct

- then there's a host of other small shops that make custom ti- 10spd shimano cassettes
Thanks again, question...DeRanger

...I'm a pretty big dude - 6'3", 220# (and even if I ride like a fiend I'm not likely to ever dip much below 210# - truly big-boned). It sounds like trying to make the Cosmos conform to the gruppo is not the best way to go. Going with the Protons sounded like a good idea (although about a C-note dearer than the Cosmos), but I recall reading that for riders over 6' tall the Protons were not recommended - too flexy.

Can anyone suggest a good wheel for a clydesdale like me?

Lose the factory wheelsKerry

Protons are fine, and their flexibilty has nothing to do with rider height, but rather rider weight. You'll have a bunch of cash, get a good wheel, etc. if you just go with something like a 36 spoke Velocity Aerohead. A well built wheel with Centaur hubs will serve you very well, be easy to maintain at any good bike shop (or in your basement if you have the skills), will weigh about the same as the factory wheels, and be plenty strong. What more could you want?
