    I upgraded from HG series that came on my Specialized Stumjumper FSR Comp. That one lasted me a couple of YEARS! I ride at LEAST 3-4 times weekly, AND race Kenda Cup, & other x/c races. I wanted to save weight, and retain the smooth shifting I have had since I bought the bike. I got 11-34t w/5 splines. No durabilty problems. I weigh 145lbs. I don't know why people say they bend these things. I think they probably recklessly shift under load like they're riding a motorcycle or something. I don't think you are supposed to do that on a bike. That's just my opinion.

    Great cassette but needed work ? ?

    Had Jenson install when purchased and immediately noticed a faint spoke sound. After a few rides i had thought i had a few loose spokes but every time i checked them i found nothing. As the sound grew louder i had finally found the problem, shimano had designed the big sprocket with pins integrated as to protect from "chain damage to spokes" but these little pins had hit all spokes slightly damaging them. The sprocket had to have the pins lightly ground down with a dremell to clearance the spokes. I would have given it 5 stars but due to the fact that i was replacing the same exact cassette with a new one and the old one did not have the pins and now i had to modify a new cassette, i knocked it to 3 stars. Had jenson caught this on install i would had just bought something else and saved myself some time and spoke damage. If u are thinking the freewheel hub had play it was replaced weeks earlier so that is not the culprit. BTW who has had a chain jump over the large sprocket on the cassette ? Every time my chain derails i am flying and my chain falls to the smallest cog!

          Comments about Shimano M770 XT 9 Speed Cassette:

          Replaced an identical cassette because of problems shifting due to two largest sprockets being bent. I'm thinking they got bent from crashes but I've read other comments about these bending just because they're flimsy. Been using the new one for about half a dozen rides (~ 50 miles) without any problems. So far so good.

            Installed on my new Titus ML in 2006 and still going strong. Changed out the chain regularly and lube chain with White Lightning and no skipping etc. I've ridden ~ 30 times per year including trips to Moab, Kingdom Trails VT a few times etc etc. Tons of miles!

                Here you got a wonderful value from Jenson! These are light and durable and for 57 bucks you just can't complain at all! I have used the HG 750,760 and 770, and they all are consistent in their performance, just the finish is different(cheaper for sure on the 770) but the performance and longevity are the same. Highly recommended!

                    I had to change my cassette out as it's been on my bike for a number of years now. I've read the reviews and talked to people that have had this model, so I tried it.

                    After about 5 months, I have no complaints, it's worked like it should. Buy it, it's easy on the pocket book, easy to install and it just plain works.
