Rated 4.8 out of 5 by 78 reviewers.
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
Rated 5 out of 5 by Works well Not a lot you can say about it really. Its not heavy, it is well made and finished, it shifts really sweet even with a SRAM hollowpin chain (always my prefered choice). For the knock down price these are being sold for its a bargain really. 13 August 2014
Rated 2 out of 5 by dura poco. it lasts not much. la prima cassetta xt era nuova sulla mtb olympia che ho acquistato, con catena xt. dopo 7500 km ho dovuto cambiarla perchè saltavano le cambiate. ho un cambio sram X0. ho preso un'altra cassetta xt. la catena ho messo prima una sram 1071 (cambiata a soli 2500km) e poi una KMC X10.93 (cambiata dopo 3500km). appena mi hanno dato 0.75 sul misura usura della catena le ho cambiate. due giorni fa ho messo una KMC uguale. ma la cassetta xt è già mangiata, mi saltano le cambiate sulle due velocità più piccole. quindi è durata 6000km (2500+3500km). io vado in mountainbike da quasi 17 anni. adesso ho una fullsuspended. cambio spesso, vista la comodità del grip shift sram. faccio 5000-6000km all'anno. una cassetta xt mi dura 6000-7000km. non ha importanza cambiare la catena ai primi segni di usura o tenerla su di più. la cassetta xt dura poco. devo cambiarla 1 volta all'anno. le cassette xt della la mia prima mtb (mongoose) hanno fatto 15-20.000 km l'una! con catene xt e sram (una catena faceva 7500-10000km). mi duravano 3 anni. i pezzi che fanno adesso durano anche un terzo rispetto a quelli di 10 anni fa. a questo punto penso lo facciano apposta. così obbligano al cambio più spesso. non so se un xtr o cassette più costose durino di più e valgano la spesa. non so neppure se altre marche durino di più. forse la prossima cassetta provo una sram. 06 August 2014
Rated 5 out of 5 by XT 10 speed best at price performance ratio This is a really good product - compare the weight and what you are paying to the higher end models and you will see why. XT also lasts very well 03 August 2014

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).

Answers

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: 
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.

I currently run a Shimano HG62 cassette 10 speed.
Because the HG62 is on steel carriers, it is chewing free hubs badly.
Is this cassette a fully compatible replacement (alloy carriers) to the HG62 cassette, even though my rear set up is DYNA SYS??
And do you reccomend the XTR HG-X chain to run with it?

Many thanks

Casette Updgrade

I am currently using a Shimano M442 44/32/22 Crankset and am looking for a new casette. I am unsure of the spec of the current Casette so really am unsure as to what teeth on the new one would be optimal? Or even what the differences are between the two. I just want to make sure they are compatible.

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.

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.

The main difference is the weight. XT is 50-80gr lighter. They are both made of quality steel, so durability is approximately the same.
