    Shifting, elevated.

    In the never ending conundrum of one-by gearing choices, we've spent many a day opting for ten-tooth speed only to end up grinding over merciless grades and wishing that an extra climbing gear could somehow fly out of the sky and save us in our time of knee-breaking need. With a massive gear range across 12 cogs, SRAM's Eagle drivetrain swoops in to save the day and provide nearly the range of a two-by system in a simple one-by setup. The SRAM X01 Eagle 12-Speed Rear Derailleur ties the system together, driving precise gear changes across the entire cassette with a titanium spring and durable, forged aluminum body.

    Similar to SRAM's 11-speed offerings, this little derailleur borrows a boatload of technology from its flagship XX1 sibling to create a budget-friendly, clean-shifting ride experience. The Roller Bearing Clutch, long revered for its nearly unbeatable chain stabilization, gets an update with a repositioned upper pulley and larger lower pulley to accommodate the extra chain length needed to run such a wide range of cogs. Paired with a strengthened clutch, it efficiently manages chain tension to eliminate derailleur bounce and chain slap for a solid, noise-free ride.

    The X-Horizon feature further boosts this stability by limiting the derailleur's shifting movement across the horizontal axis, with its large upper pulley design maintaining a constant chain gap across the cassette. This effectively reduces shift initiation force and eliminates pesky ghost shifting, so you'll drop into the right gear with minimal effort the second you want it.

    Last, but by far not the least, is SRAM's Exact Actuation technology addresses the issue of different gears requiring different amounts of cable pull to shift, which leads to loud cassettes and inefficient shifting. With Exact Actuation, each gear shift requires the same amount of cable pull, resulting in a predictable click and shift no matter where the chain sits in the cassette. This also means an overall quieter, better adjusted drivetrain for predictable shifting in any situation.

    Shredding trails inevitably involves a mechanical or three, and the X01 Eagle 12-Speed Rear Derailleur makes the ensuing wheel swaps and maintenance easier with an update to SRAM's Cage Lock functionality that sees the lock pin tucked a bit more out of the way for additional protection from impact. Its overall functionality remains the same—just push the derailleur forward and it locks into place for quick and easy rear wheel removal or installation to get back out on the course in a snap.

    Smooth

    • Familiarity: I've put it through the wringer

    This Derailleur, paired with the rest of the appropriate bits, offers smooth shifting over a HUGE spread of gears. The system has been really good so far, just might take a bit longer to get the rear derailleur tuned in compared to other systems. I've found it's picky on the chain length. Once dialed in though shifting has been nice and crisp.

    No misses!!

    What can be said about the new Sram eagle group other than it is excellent! Smooth shifting, light weight, durable, huge gear ratio, and being able to run a larger ring up front without losing your climbing abilities? What's not to love? I have been a die hard Shimano user for the last few years, and though I still think Shimano is great, eagle has definitely converted me over.

    Beautiful

    • Familiarity: I've put it through the wringer

    I have been loving the new SRAM X01 Eagle drivetrain. It has performed with minimal maintenance—not recommended—and helped pursue my passion to ride diverse terrain with one bike. With any new technology in the bike world, there is a cost to getting on the newest and greatest advancements—the Eagle is fresh to the market and currently the only 1x12 drivetrain available—and the price tag reflects the exclusivity. Per usual, prices do tend to drop after time (although there is no concrete evidence of that happening anytime soon). However, even as is, I think the price tag associated with the new 1x12 systems is well worth the money and will only increase any on-trail experience and offer a whole new range to you daily ride.

    Eagle Power!

    • Familiarity: I've used it several times

    I recently built up a new bike with Eagle X01. I've been a 1x convert for a couple of years, and the addition of the 50t cog allows me to ride a larger front chain ring without sacrificing the bail-out gear. The shifting is smooth and precise but my favorite feature of SRAM rear derailleurs is the locking mechanism. It makes removing your rear wheel quick and easy.

    SRAM 1x reliability with a bailout gear!

    • Familiarity: I've used it several times

    This stuff has been great. I used their 1x11 drivetrain basically since it came out, and the new Eagle 1x12 is perfect for me because I get the same cassette and gear ratios with a massive 50t cog attached which works great if I hit a steep digger. The new derailleur is awesome, shifts are crisp and precise, and I've noticed lower noise from the jockey wheels than the previous 1x11 stuff.

    50tooth!

    • Familiarity: I've put it through the wringer

    The extra gear you have been wishing for is finally here. Now you have a 50tooth bail out gear for those long and hard climbs. I personally jumped up to a 36 tooth chain ring to have a larger gear. With that 36 tooth, when the chain is in the 50 tooth gear it is still easier than when I had 34 tooth.

    Fly like an Eagle

    Sram has updated their 1x group and added an additional gear. This new derailleur has been updated to cover the spread of the new 10-50T cassette. Not only does it cover the spread with ease but it does so with a direct yet buttery smooth shift feel. If you're looking for the best in 1x drivetrains Sram has you covered.
