Why We Like The XG-1299 XX1 Eagle 12-Speed Cassette
As the lightest option in the Eagle lineup, the XX1 12-speed cassette is what we throw on our most elite dream builds. Available in 10 - 50 and 10 - 52t configurations, this cassette boasts a 500 - 520% usable gear range that propels us up grueling climbs and keeps us from spinning out when we're cranking at top speed. The cassette features SRAM’s X-Dome architecture to deliver one of the strongest and most consistent performing cassettes on the market, and it’s finished with Ti Nitride, which helps shed mud and ensure smooth, reliable shifting in all conditions while looking oh-so-slick in the process.

A worthy upgrade
- Familiarity:
- I've put it through the wringer
- Size Bought:
- 12 speed SRAM Cassette
I had installed the XX1 cassette previously on my 2021 bike (road/gravel) and was very pleased with it. I went ahead and installed another XX1 cassette on my 2023 road bike. A significant reduction in total cassette weight. Combined with the XX1 chain on both bikes, the shifting with a conventional SRAM derailleur set-up is smooth and without issues. I can recommend the XX1 Cassette without any reservations.

Huge improvement
- Familiarity:
- I've used it once or twice and have initial impressions
I have noticed a significant difference on the extreme uphills with the extra 2 teeth compared to a 10-50t cog. The gold color looks awesome and I am enjoying the full new SRAM drivetrain as compared to the cheaper NX I had on my bike from the factory.

The SRAM Factory In China Is Not Back
- Familiarity:
- I returned this product before using it
I bought this cassette and it was defective. The threads were bent so when I attempted to install the cassette it was crooked. Boxed everything up and sent back to Backcountry.

52T, 52 Weeks?
- Familiarity:
- I've used it once or twice and have initial impressions
As of this review, the new SRAM 52T is still fairly new and making it's way out to the masses. I recently upgraded to the AXS drivetrain and felt that it would be appropriate to bring on the new 52T cassette. I purchased it from my LBS on 8/12/2020 and was STOKED because I had some big climbs (3-4k) on the schedule for August into September. As expected, everything was flawless and worked with precision and the crispness you'd expect. 9/18/2020 - I was doing routine maintenance on the bike and while lubing the chain, I noticed one of the Tooth on the 52t cog was chipped. No more than 40 hours on the cassette, I was in complete shock. I like to think that I ride "hard" but it's a brand new cassette. I've got a warranty submission via LBS, I trust that SRAM will take care of me. I'll keep you guy posted.
