Rated 5 out of 5 by Excelent cassette You just can't go wrong with Shimano. Quality 2nd to none, smooth shifts, light weight and long wearing. 23 September 2014
Rated 5 out of 5 by bulletproof cassette Cheap, hardwearing and light! What more could you ask for! 36t also matches single ring setup too 23 September 2014
Rated 5 out of 5 by ottimo ad un prezzo imbattibile Ottima funzionalita, peso giusto in proporzione al prezzo. In offerta da nn perdere... 20 September 2014
Rated 2 out of 5 by It falls apart! I bought one and after about 700-800km the pins holding the 3 middle cogs together simply gave up! I contacted CRC - BRILLIANT SERVICE! - they replaced it for me with no problems at all :) But it happened again. The middle cogs are rattling already, I the pins are just about to fall out... I don't recommend it. It's extremely fragile on the spider. The look and few grams saved over Deore is not worth to pay extra. And I don't ride any hardcore stuff! Commute, some easy/moderate single track, few rocks, no jumps (I'm too old!)... 12 September 2014
Rated 5 out of 5 by Excellent product and competitive price (on sale) Great, like all of the XT product line. Possibly the best in terms of performance/dollar value. 06 September 2014

Answer: 
The shimano 10 speed range is all part of their new dina sys branded kit. It refers to the narrower spacing of the cogs on the rear cassette and the ratios over all, along with some improvements in shifting.

You can see further details in the shimano website -http://bike.shimano.com/publish/content/global_cycle/en/sg/index/news/dyna-sys__shimano.html

If your question is will it work with my current MTB 10 speed setup, then the answer is probably yes, but ask another question saying what kit you're wanting to replace if you want to be sure.

Answer: 
Yes, the 2012 LTD ran a standard Shimano/SRAM style 10sp cassette, so this XT M771 should be fine. If you are replacing the cassette with one of the same size you should be ok to continue using your existing chain (although it is generally considered good practice to install a new chain with a new cassette/ chainrings to ensure efficient engagement).

Answer: 
If your Cube bike is already a 10 speed setup, regardless of whether it is SRAM or Shimano the this 10 speed cassette should work fine. If your cube is 9 speed then purchase a 9 speed cassette. A 9 speed chain will be a little too wide for a 10 speed cassette, plus other compatibility issues with the shifter and derailleur.

It should be fine as long as you use SRAM shifters. Any HG-X or compatible 10spd chain is fine too be it KMC SRAM or Shimano. Make sure you get the gear ratio best suited to the type of riding you do.

Answer: 
The 4600 10sp Tiagra rear derailleur only runs a 30t maximum sprocket capability so you may have trouble setting one up to run a 32t cassette effectively. The largest cassette ring should only be a 30t (or 28t if running a triple with a 52t front ring).

Answer: 
That is a good question. Others may correct me but XT is a model or two up from the SLX range. This leads me to make the assumption that they are stronger, longer-lasting, possibly lighter and on the downside - more expensive. I have just brought an XT chain so I will write a review after a few uses.

Casette Updgrade

Answer: 
This is a 10-speed cassette; as the Shimano M442 crankset is for a 9-speed drivetrain, this cassette will not be compatible.

The easiest way to determine drivetrain speed is to count the actual number of sprockets on the cassette itself.
