- New X-GLIDE 2 improves both inboard and outboard shifting, as well as chain retention
- ISO 4210 compliant
Features
- This XG-1275 cassette is an integral part of the SRAM Eagle drivetrain system
- FULL PIN tech: 11 steel cogs, 1 aluminum cog, held by stainless steel pins
- Super wide 10-50t gear range—a perfect fit for any ride
- Optimized gear steps across entire range
- Open design aids in mud clearance
Wide Gear Range
With a 10- to 50-tooth range, this cassette provides the right gear for riding anywhere
Offering speed on flats and control on climbs, allowing riders to dictate their pace in any terrain. Designed specifically for 1x drivetrains, Eagle technology offers unparalleled freedom and versatility, allowing riders to explore various terrains without compromise.
- The use of lightweight stamped steel cogs held together with high-strength stainless steel pins results in a cassette that is both light and strong, ensuring durability and performance on the trail
- Similar to SRAM's X-DOME cassette, the open design of the XG-1275 aids in mud clearance, improving shifting performance and prolonging the life of drivetrain components
- The new X-GLIDE 2 technology improves both inboard and outboard shifting, as well as chain retention, providing smooth and reliable shifting performance in all conditions
X-SYNC
Features alternating narrow-wide teeth that mesh closely with the inner and outer links of the chain. This design effectively prevents the chain from derailing.
- The precise shaping of X-SYNC teeth ensures consistent interaction with the chain
- This design delivers crisp shifting and reduces chain noise during operation
X-GLIDE 2
X-GLIDE 2 technology optimizes the shape and profile of the teeth on both the cassette cogs and the chainrings. This optimization results in smoother and more precise shifting, both when shifting up (outboard) and down (inboard) the cassette.
- Also contribute to better chain retention during shifting
- The improved engagement between the chain and the teeth reduces the likelihood of dropped chains, especially during aggressive riding or on rough terrain
- X-GLIDE 2 helps reduce noise during shifting, resulting in a quieter and more pleasant riding experience
- X-GLIDE 2 technology is compatible with SRAM's 1x and 2x drivetrains, providing consistent and reliable shifting performance across various gearing configurations

Rather than transfer over from my aluminum rims, i bought all new parts while building my ne CF wheelset.Sram cassette was easy. Remember 40nm torque

Exactly what I need but does not come with a spacer for my XDR application. New, boxed and shipped reasonable fast. Would purchase again.

I have been riding GX for several years now and it shifts so smooth. I did have to replace this after 5 years of daily hard riding and coaching, but for the price and longevity I will continue to buy GX and ride with it.

I was trying to save money and purchased this on sale for a great price. I am using the XX1 cassette on another bike, but didn't want to spend that much money this time. I kind of wish I had. The cassette is well made and works OK. It is pretty heavy. Not as heavy as the NX cassette I have for a backup set up wheels, but still fairly heavy. The shifting isn't as good as with the XX1 cassette. That is the reason for the deduction of one star. I feel like it should shift just as well, but it doesn't. It does shift cleanly in the higher end of the cassette. The sloppy shifting is in about the three lowest gears. (The three largest cogs.) It does work and they do go into gear. Just not as cleanly. So, I would recommend it if you don't mind the extra weight since it is 1/3 the price of the XX1.

The SRAM XG-1275 GX Eagle 12-speed cassette is... big. The cassette itself arrived in excellent packaging with the actual product positioned almost like a presentation. The second I opened the box, I was taken back at the dinner plate-sized 50t cog - it's larger in diameter compared to my 180mm rear brake disc! The cassette itself is nicely built, with full pinned cogs for a one-piece installation (XD Driver compatible only). Installation was a breeze, and I was rolling in no time. Coming from an 11-speed Sunrace cassette (which was quite good, actually), the GX Eagle cassette was still much better. The 50t cog let me climb uphill trails with more distance and less effort. During shifting, the chain shifted up and down the cassette gears with precision and barely any noise - a welcome absence, since I was used to the shift noise of the Sunrace cassette I was using previously. I did not weigh the GX Eagle cassette for comparison, but even with the extra gear it felt pretty close to my old 11-speed cassette in terms of weight.NOTE: I purchased the GX Eagle 12-speed rear derailleur, XG-1275 GX Eagle 12-speed cassette, GX Eagle 12-speed trigger shifter, and GX-Eagle 12-speed chain. The next portion of text will be repeated in my reviews for the other items as well)Coming from an 11-speed setup, and I can't tell you how big of an improvement/upgrade it was! For the price of entry (about $375 for the groupset, minus the cranks) the entire GX Eagle system works so well, it feels just like the X01 Eagle system but without the gold bling and more importantly - at a very affordable price point. Shifting is crisp and satisfying. Drive train noise is actually surprisingly quiet. Thanks to the wide range of gears (and the 50t cog!) I can tackle more climbs for longer time periods with less effort. I'm completely happy that I made this upgrade to GX Eagle, looks like SRAM has made 12-speed both reliable and wallet friendly. I wish I had this group set a long time ago!
