A chain that’s more than the sum of its hollow pins or its fanatically shaped chamfers. Because it takes more to make a chain XX1 Eagle worthy. XX1 means uncompromising strength at an ultra-light weight with performance consistency and silky smooth, whisper-quiet operation. Now completed with SRAM's all-new Eagle colorsystem setting the aesthetic bar and giving riders color options from Black to Gold to Rainbow, including all-new Copper. Designed and manufactured in SRAM's European facilities, it’s the quietest, strongest, and most wear-resistant chain in the world.
SRAM chain engineers developed PowerLock as a tool-free, easy, and consistent way to connect their chains. While PowerLock does not require special tools for installation, the especially tight tolerances of 10- and 11-speed drivetrains result in the PowerLock being good for one application only.
Eagle Technology represent SRAM's newest 1x drivetrain tech. Eagle is a lighter, simpler, more durable, and easier-to-use drivetrain. Featuring all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. SRAM's Eagle lineup also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.
Ultra-smooth inner plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, giving you quieter performance and better wear life. The design allows a narrower profile that can withstand greater angles and also allows for a flatter outer plate, meaning more consistent chain riveting and enhanced overall strength.
SRAM Hard Chrome chains offer 4x more elongation and wear resistance than other SRAM chains. Thanks to the new finishing process on the inner links and rollers, these chains last longer while offering the same ultimate strength SRAM chains are all known for.
SRAM X-Sync 1x chainrings provide the highest level of performance and durability. The tall, square teeth edges engage the chain earlier than traditional, triangle-shaped teeth, and the sharp, narrow tooth profile and chamfer edges help manage chain deflection. Designed with mud-clearing recesses on the inner chain links and rollers, this chain offers the best possible performance in muddy conditions.

They had a sale going on and I was looking for a replacement chain from X01 sram eagle axs it was a great price. It was a problem with with shipping who had nothing to do with the seller they quickly expedited a new chain for me. I really appreciate what the customer support they have. I’ve bought many items from them and I will continue to support them.
SRAM products are top notch. I push hard every ride rarely having a “chat pace” and their components have stayed right with me never failing.
Who knew a chain could do so much!
Awesome product! Will buy again
Chain is awesome! Shifts crisp and clean. The gold looks fantastic. Very happy with it.
Easy transaction and fast shipping
the XX1 CHAIN IS WORTH THE EXTRA MONEY BECAUSE THEY DO LAST LONGER. AT THE PRICE THUNDER MTN HAD ON IT, IT WAS A NO BRAINER.
Fast shipping and better price than I could find elsewhere. Highly recommend!
These chains are your dad.
Am extremely long lasting reliable and easy shifting chain
I was surprised how well the previous chain shifted. I was shocked how long it is lasting
Thank you!
Great chain on sale bought two to have a spare.
Great product
They seem to be lost in USPS land. But I like these chains a lot. We’ve been riding them on our MTBs since 2019. I feel like my chain rings and cassettes run smoother and wear slower with these chains.
its debatable if the durability out weighs the cost for upper level sram chains.
they do nicely outlast the GX and X01 level chains. they look nice doing it is a bonus,
Worth every penny, specially when it's drum thunder mountain bikes!
Great chain at a great price and shipped fast.
I tried to buy a chain from an online competitor when they were offering 20% off, but oddly, the chain was excluded from the sale. Then I saw a 20% off sale from Thunder Mountain and they honored it. Done deal. Thanks Thunder Mountain!
Pretty awesome!!
Excellent product mix & super follow up.
Lasted 3x longer than the Sram NX Eagle.
So far so good. Been putting the XX1 through it's paces on the tail and dirt jumps. No rust or discoloration, which is a very nice change......
This chain is not only great looking but performs incredibly.
XX1 Eagle chains are worth every penny! I have over 5k miles on a gold one that came with my bike and it still shifts like new.
I’ve never had an issue with the XX1 chain. They’ve been flawless and smooth.
First time with a high end chain. Usually use nx or gx chains. This gold one is absolutely beautiful.
Great chain and solid lifespan. Used before and it lasted 2000 miles.
product was what I ordered and arrived in stated timeline. great price. will definitely order again!
XX1 is definitely worth the price. Love the color ops, too!
After 4000 miles it was time to replace my old one. These chains are bullet proof
