Shimano CS-M770 Cassette 9 Speed Deore XT

Light weight, wide-range XL cassette. Lightweight for the size, (290g). Cambria provided this product at a very competitive price and the shipping was lightspeed. I wouldn't hesitate to buy from Cambria in the future!

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 ... MoreHad Jenson install when purchased and immediately noticed a faint spoke sound.

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!PROS: Durable, Precise ShiftingCONS: Difficult To Install

Yeah, it's the same cassette that came on my bike when new, but it's been SIX YEARS of hauling this chubby guy around that proved the original's demise.It's not the nicest, nor the entry-level cassette, but it does it's job, and if it holds up for another six years (I promise I'll rotate it out beforehand this go'round) then I'll be quite impressed... again.The bike shifts and drives like it did when it was new. I changed the chain, and converted to a single front ring at the same time which contributed, but the cassette is where the magic happens.I'd buy this again in heartbeat if I'm still alive in six years.
