SRAM X01 11-Speed XG-1195 Mountain Bicycle Cassette

Set this up on a new build with a X01 rear derailleur and shifter, XX1 crankset and KMC X11SL chain. First, the finish on this component is outstanding, as would anything with this level of exquisite machine-work, and all that machining comes at a cost. These suckers are expensive, far more than their 10-speed brethren. But are they worth it given the plethora of DIY 1x10 solutions out there? My assessment is that would depend on your budget. My initial impression on the trail is extremely positive, likely the result of the outstanding synergy between the components of the SRAM 1x11 drivetrain system. You gamble on that kind of synergy with a Frankenstein-ed 1x10. Shifts, even uphill under duress, are quick and positive. Given the cost, I'm concerned with tooth wear, and you can bet that I'll be diligently swapping chains and using generous amounts of lube.

As a competitive mountain bike racer and Team USA member, my gear goes through alot. The SRAM cassette is superbly made, and while lightweight, it holds up well. The largest ring can be replaced, and even an after market bigger ring can be applied.

Good stuff. Replaced my XX1 that lived on the bike for 2 years. The 42 ring had become worn out. Search for amazon wearhouse deals!

This is one of the better purchases that I have made for my fat bikes. I noticed an immediate performance increase following installation.

REPLACED A GX11 CASSETTE WITH THIS ONE-NO REGRETS

I like the black. looks good on my bike. functions just like the XG1199

Unbelievably lightweight! So far, so good.

Works well! - Note that the Park tool will not be able to tighten this if you have a 142 thru axle. The park tool (FR-5) bottoms out on the axle and will not tighten all the way.
