Sram XG-1275 GX Eagle 12-Speed Cassette

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!

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.

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

Lo recomiendo súper bueno

Excelente

es un producto de excelente calidad ya comprobado. Sigue siendo asi. Sram es asi.

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.

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
