|   Difference between M952 and M953 XTR cassettes? | mr_spin
Oct 11, 2001 8:07 AM | | The M953 is the "Mega-9" version. As we all know, anytime they use the word "Mega" it has to be better, right?
Is there any real difference? Besides the $15-20 in price. I have the M953 now. |

Oct 11, 2001 10:38 AM | | the m952 is the same cog sizes as the 953. same number of Ti cogs too. The 952 is about 30 grams lighter.
The 952 has the largest 6 cogs mounted to 3 separate spiders. the 953 has 6 cogs mounted to one spider, just like the XT models.
The 952 is sweet to look at and crazy light. But, its TOO light. The 952 was replaced very quickly with the 953 when Shimano figured aout that the largest two cogs liked to fold over onto the next smaller 2 cogs. It was just too flexy.
If someone has a 952 that folded like a taco, Shimnao will replace it with the 953 for free - they know its bad, but have not recalled it formally. The 953 uses the single spider like XT and also has a little more "depth" to the largest cogs - they are a bit taller I guess you would say.
I have personally folded two of the 952's - both times in crashes - so who can really say what caused it to fold.
If you know what a Dura-ace cogset looks like, the 953 looks the same. |

Oct 11, 2001 8:44 PM | | I've run both myself and can vouch for the wt differences and construction differences. However I've never tacoed a 952, though I admit I'm mainly a light XC rider. |
| Which is why I prefer ActionTec for Ti cogsets... | DeeEight
