On a serious note. I cannot find a CS-M775 anywhere to do a comparison

[AndreZA]

sometimes it's just a small change in material or design from the one year to the next.

There is no such thing as a XT cassette CS_M775.

 

there is only the CS-M770, or CS-M760 or CS-M750.

the 775 refers to the brakes ie. a BR-M770 is the V-brake version whereas the BR-M775 is the disc version

True, but the topic says XT Cassette and you do get a CS-M770 which is a cassette. Here is the complete list of M775 items from Shimano:

 

BL-M775 Disc Brake Lever
BR-M775 Disc Brake
FH-M775 Rear Freehub
HB-M775 Front Hub
ST-M775 Dual Control Lever for Disc Brake
WH-M775 Deore XT Disc Brake Wheels

 

2wh33ls, if you want to get the details of any given part, just go to http://techdocs.shimano.com/techdocs/index.jsp and put in the product code.

Ok, I think I have the real answer. The CS-M750 (9-speed) was manufactured from 2000 and the spacer rings were made from steel. The CS-M770 was manufactured from 2008 and the spacer rings were made from aluminium. The CS-M770 is almost 50g lighter than the CS-M750 cassette. The CS-M750 uses a hyperglide body and the CS-M770 uses Hyperglide-C body. The "C" stands for compact and means the freehub body will accept an 11T small cog.

thanks, I found on CRC

They don't say anything about V brake or disc brake version.

Also just say it's a M770 - I hope it will fit on my disc wheel

I agree the topic says cassette, but the question is the difference between 770 and 775, there is a CS-M770 cassette but no CS-M775 cassette which is the crux of the question...

The cassette is the same... there is no CS-M775 cassette, the "5" at the end refers to the brakes only.
