Shimano MTB Cassettes

Who knows about Shimano XT and XTR cassettes?

I have a vintage GT Xizang (titanium frame) mountain bike, with XTR throughout. In shopping for a new cassette for a second set of wheels (with Marathon Plus tires for touring and utility use) I'm considering XTR M960 vs. M975 vs. XT cassettes. Big price shifts!

I want not only light, but super-durable. And maybe consistency in staying upper-end Shimano components is an ego thing, I don't know.

What would you do? How much real difference is there?

Light and super durable huh? Pick one.

Anyway, the major difference between the XT and XTR cassettes is the XTR has the largest 4 (5 on the new 10-speed) cogs made of titanium which reduces weight, reduces durability and increases cost. XT cassette cogs are all steel so it's heavier, more durable and cheaper. As I said, pick one.

xizangstan, If you've an 8S try the M737-1 11-28 cassette. Works well for my flat terrain and the street.

Thanks, but I've changed over to a 9-speed rear. I was thinking 11-32 gear range, for mostly road rides.

Of the two - lightweight and durability - I believe the most important is durability. Weight is a secondary consideration. But when I'm loading down the rear rack with a gazillion pounds of stuff, I don't suppose a couple grams more weight won't hurt. I just don't want to lose control on the weight consideration issue, though.

Done.

I asked you guys for your advice. Most of you told me to go with XT. I did. It should be here in a couple days.

Thank you.
