Your cart is empty. In 2012, SRAM 'turned it up to eleven' and the MTB world changed, now they have gone a step further with the brand new Eagle XG-1299 12 Speed Cassette Gold. Offering a greater range of gears at the back for serious hill climbing a a bigger choice at the front for trail riders and racers alike, SRAM Eagle takes shifting to another level once again. The new XX1 Eagle Cassette is both lighter, more durable and stronger than anything that has come before. With a massive 10-50 tooth range and 500% gearing ratio, nothing matches the performance of the Eagle Cassette. Pick up a new Eagle XG-1299 12 Speed Cassette Goldas part of your upgrade to Eagle.
Moving to twelve speed means a change of shifter, chain, cassette and crankset. Luckily, Biketart has the full range of X01 and XX1 Eagle, right here. This first look from Bike Radar helps you to compare the advantages of 12 speed over 11 speed.
Features:
Greatest durability and lightest weight on market
Smoother, quieter system with enhanced inboard and outboard shift performance
XD driver body compatible

Obviously you get what you pay for and this cassette is pricey. Flawless shifting as expected

My old XX1 Cassette is 5 years old and still in great shape. Purchased the new one because of the smoking deal. I run a 32 chainring paired with the 11-50 gives me plenty gearing, even for the long steep climbs so the 52 wasn't considered. I'm not gentle with my shifting and I'm a masher. This cassette paired with the XX1 chain has proved to be indestructible. My rides are mostly on dry, sandy, rocky and root covered terrain which requires constant drivetrain maintenance for longevity. Average over 1300 miles of CC/moderate singletrack a year on the front range. Definitely a recommended product.

I had tried the GX Eagle cassette to run with my GX Eagle mech and chain, but it had the common 4th/5th gog ring issue which isn't acceptable on a brand new cassette. I decided to pay the extra and go for the XO1 and I am delighted. I installed the cassette and the difference in performance was instantly noticeable. Gear changes are crisp and the drive train runs as smooth as silk. If you have the budget I would recommend this component.

I purchased this as a replacement of a circa 2016 original component on a stock bike. Installation and tuning was seamless and the drivetrain worked flawlessly after mounting and tuning. I've been using it over a year in harsh conditions with no problems.

What did I like? The cassettes are almost a work of art, the shifting is sublime, and they generally last a long time. What don't I like? They cost as much as a nice used Volvo. Yeah, you can get a cheaper Eagle cassette, but the weight difference is significant. Who needs that first child, anyway?

Awe inspiring - best words I can use when I opened the box. I was shocked at how big the cassette was and how little it weighed. The rainbow finish is amazing too - I'm not really into bling but it added quite the punch to my bike. Overall installing the AXS system I shaved nearly a full pound of my old X01 / GX Cassette . Having a sub 24 pound full suspension mountain bike that shifts like an F1 car is pretty freakin awesome !

Als aller erstes muss ich sagen war der Versand der Hammer!Heute Mittag um 12:34uhr bestellt und es kam gerade um 20:30 Uhr an.Gefahren habe ich es noch nicht und auch noch nicht montiert aber der Look und die Verarbeitung sind wie man es von Sram kennt einfach mehr als optimal!
