Rated 4.6 out of 5 by 17 reviewers.
Rated 4 out of 5 by Calidad y fiabilidad Shimano. Buena relación calidad-precio No tan ligeras como pudiera parecer por su precio en comparación con unas Deore o SLX, entre 60 y 80 gramos. Lo que si se ve es una buena terminación en las bielas en comparacion con las de gama inferiory su excelente estética. En Chainreaction se pueden encontrar todas las medidas de las bielas, cosa que en España me fue del todo imposible. 05 October 2014
Rated 2 out of 5 by 2 sets broke in 2 months I have been running XT for ages about 2 months ago I bought 2 sets of the new black ones to upgrade and on both sets the left none drive pedal side (to different makes of pedals so not pedals) tore out of the crank, so I now have 2 virtually new sets of cranks but no left side and Shimano would not warranty them at all, 26 September 2014
Rated 5 out of 5 by Best value ever with great quality. Works with 9 speed. Smooth shifting, efficient pedaling, very light with the hollowtech II and hollow bottom bracket design. The middle ring where I spend the most time in, is carbon reinforced, which will ensure it lasts a lot longer. Sweet looking in black. There are aggressive ramps built in to help in the shifting up. I prefer the way the crank arm is secured with two opposing allen bolts as compared to the my XTRs that has a single threaded nut through the axle. 1. It works with a 9 speed system. Don't let anyone tell you otherwise. Works with the old Shimano XT Front Mech and Shifters. Adjusted the front mech position lower as I went from an old XTR 44 teeth to the current XT 42 teeth (therefore smaller). 2. I use a 9 speed XTR chain, as the chain must match the cassette. If you are using a 9 speed rear cassette then use a 9 speed chain. It doesnt matter if the 3x10 crankset is in front. If you are not a pro racer or someone with loads of cash, get the XT! When my XTRs were worn out, I replaced it with XTs and I do not miss my old XTRs much. 19 August 2014
Rated 5 out of 5 by XT say no more I used these on a build to replace Deore cranks from the donor bike. They aren't much different to the Deore cranks in design, but feel lighter and stronger. These and XT shifters gave me a full XT drivetrain and to be honest it feels superb and great for XC and trail riding on my hardtail. Have SRAM and Deore on other bikes and you can tell the difference with XT. It is close to my XTR drivetrain on my full sus AM bike. Make sure your entire drivetrain setup is dynasys to go with these cranks. This doesn't mean all XT. You can use a mix with any new 10 speed labelled dynasys from Deore up. 18 August 2014
Rated 5 out of 5 by Great Stuff This is a great bit of kit,strong and looks good in black.ruuning along with the XT rear mech is nice and smooth 14 June 2014
Rated 5 out of 5 by Great Cranks These cranks are absolutely awesome, they are strong and deliver excellent power with each stroke and is also very smooth. I'm running these with the XTR chains and absolutely love it. 11 May 2014
Rated 4 out of 5 by Value for money Initially wanted to go for XTR crankset, but after reading a lot of reviews and personally trying out, actually the performance not much difference except the weight. 07 May 2014
Rated 5 out of 5 by So far sogood XT M780 appears to be a good choice so far for my Merida big 7 500. Looks good, seems well built and strong. Also not bad looking on the eye! 04 May 2014

Answers

Answer: 
The bottom bracket on the frame at present would need to be changed to the bottom bracket included with the new crankset.

To get the best performance it is advised to select the 9-speed variant of this crankset; which will offer better shifting performance and better engagement with the chain.

The tool for installing this crankset is found listed below also with the 9-speed M770.

Answers

Answer: 
If the crankarm length on your current crankset is giving you no problems when cycling then it is best to stick with the same sizing.

Simply measure your current crank 'center to center' for the measurement required (see image here - http://i.imgur.com/d8ipefS.jpg)
