Sram X01 Eagle 12-Speed Rear Derailleur

Model: SRAM   |   Asin: B01HQE434Q

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,...

SRAM XX1 Eagle AXS 12-Speed Rear Derailleur

Model: SRAM   |   Asin: B07W375TXG

More than just a mechanical derailleur with a battery and a motor bolted on, the XX1 Eagle AXS 12-Speed Rear Derailleur is the heart of the whole AXS system. You'll enjoy instantaneous shifts from a single touch, even under extreme chain loads during the heat of racing. It's built with a lightweight carbon fiber cage and titanium hardware that make it an ideal choice for XC riding and racing, as opposed to the enduro-focused XO1 derailleur with its forged aluminum cage. It features a shorter cage for 10mm more ground clearance than mechanical Eagle, with more chain wrap on the cassette to sit slightly further forward and further inboard from mechanical Eagle, all of which gives you more clearance against rock strikes. The Eagle AXS derailleur is also smart enough to protect itself thanks to its innovative and resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, giving the derailleur freedom to move, and instantly returns back to its position while avoiding damage to the internal motor. The XX1 AXS derailleur is tested to the IP69K water and dust proofing standard so whatever race day brings, you'll be ready.

  • Material: [cage] carbon fiber, [hardware] titanium, [bearings] steel
  • Capacity: [max tooth] 50

SHIMANO GRX RD-RX812 Rear Derailleur

Model: Shimano   |   Asin: B07WDDSYLS

If you've dabbled in gravel racing and riding, chances are you already know how important a large gear range and tidy setup is, and if you have yet to experience it first hand, we can assure you, that we covet simple drivetrains with few opportunities for failure, and as many gears as possible to get us up poorly-graded hills that make up the Crusher and Kanza. With that said, it took quite some time for component manufacturers to jump on the gravel bandwagon, but with the Kanza's starting line amplifying from sub-50 cyclists to over 3,000 in just twelve years, its a welcome sight to see Shimano launch its GRX gravel-specific groupset that finds the perfect balance between MTB and Road, with a sleek and streamlined drop-bar setup, and improved modulation and bump compliance to handle off-road conditions. Shimano's GRX RD-RX812 follows in the footsteps of Ultegra RX which was launched last year, which took queues from the Shadow mountain bike derailleur, adding in a clutch mechanism to reduce chain slap and dropped chains for a quieter and more secure ride both on and off-road. When in the on position, the clutch increases the spring force to provide crisp shifting and zero chain slap and is easily flipped off for wheel changes. What we find to be big news is that Shimano crafts the GRX RD-RX810 for both 1x and 2x setups, stepping outside of the 2x only comfort zone that the brand had held to, with this short-cage model being optimized for an 11 - 34t cassette. Following in the footsteps of the revamped Dura-Ace and Ultegra groups, this GRX derailleur gets its Shadow cage treatment placing it closer to the frame and under the cassette keeping it out of harm's way and less likely to take the brunt of a driveside crash. This also allows the derailleur to move in a much more linear path allowing for shorter throws with less effort. The RX812 model comes in one cage length, long, which accommodates an 11-42t cassette allowing for a wide range gear ratio when paired w...

Campagnolo Record 12 Rear Derailleur

Model: Campagnolo   |   Asin: B07H3TVCMS

Leave it to the Italians to once again be at the Tete de la Course and provide the first 12-speed road group. Once the only groupset to consider if you were a serious road cyclist, Campagnolo has had some stiff competition from other brands in the past decade or so, but with this recent release of 12-speed drivetrain components, it aims to put the firm from Vicenza back on the wish list of discerning cyclists. At the heart of its 12-speed shifting is the Record 12 Rear Derailleur and thanks to its experience in working with race teams and years of extensive research and design, it offers not just an extra gear, but a drivetrain that brings enjoyment and performance to every ride. Campy didn't just create the new Record and Super Record group to add in an extra cog, although we do appreciate the wider range that it affords without having massive jumps between the sprockets, it took the opportunity to redesign the group entirely and build the best mechanical group it knew how to make. As such, it features 3D Embrace technology which places the 12-tooth pulley wheel closer to the bottom of the cog, increasing the chain engagement and management over rough roads and more precise and faster shifts. The derailleur's cage has also been engineered so one cage length works with both 12-speed cassettes offerings (11-29t and 11-32t). Its carbon-reinforced technopolymer upper body shaves grams without sacrificing strength while the parallelogram and cage plate made of carbon fiber maintain shifting rigidity. Campy's Ultra-Shift geometry reduces friction for smooth shifts across the cluster all while coming in at a more reasonable price than the Super Record while maintaining a near identical level of feel, though it does forgo some exotic material to keep the overall cost down at the expense of a few grams.

  • Material: [body] polymer, [parallelogram, cage plate] carbon fiber

Sram NX Eagle 12-Speed Rear Derailleur Black, 12-Speed

Model: 00.7518.119.000   |    Mpn: 00.7518.119.000   |    Ean: 0710845818028   |    PartNumber: 00.7518.119.000   |   Asin: B07DQM85PM

The NX Eagle 12-Speed Rear Derailleur provides the same precise, reliable performance you expect from Eagle, with the lowest barrier to entry we've seen yet. It shares the same technology as its pricier GX, XO1, and XX1 counterparts, but uses more budget-friendly materials for its construction. The best part is that it's compatible with all levels of Eagle drivetrain, giving you an affordable replacement option if you manage to bust your derailleur on a rock or break it during a crash. Instead of the carbon or aluminum cages found on the higher-end Eagle derailleurs, NX uses a steel cage to keep the cost down without sacrificing durability, though this does come with a minor weight penalty. It has the same X-Horizon design that eliminates ghost shifting and reduces shift force, as well as the 14t X-Sync lower pulley that facilitates the 10 - 50t or 11 - 50t cassette capacity. Continuing with SRAM's signature technologies, X-Actuation and the Type-3 Roller Bearing Clutch work together to provide quick, seamless shifting with quiet operation and no chain slap. It even has the Cage Lock button that lets you lock the derailleur in place to slacken the chain, simplifying wheel removal and installation.

SHIMANO Ultegra 11 Speed Road Pulley Wheel Kit

Model: Shimano   |   Asin: B07H994Y3R

Over time derailleur pulleys will wear out, even if the derailleur itself is perfectly fine. Usually it comes down to the bearings going bad, the pulley teeth wearing out, or maybe both. If your bearings are feeling notchy, or the pulley teeth have rounded out, it's in your best interest to replace the pulleys to get the best shifting performance out of your drivetrain. These are genuine Shimano replacement pulley wheels for the Ultegra road rear derailleur, sealed bearings included. Be sure to select the correct option for your derailleur, whether it's Ultegra 6800-series or Ultegra R8000-series. Each kit includes two pulleys, enough for one derailleur.

Features

  • Compatibility: Ultegra R8000 or 6800-series rear derailleurs
  • Recommended Use: road cycling
  • Manufacturer Warranty: 2 years

SHIMANO GRX RD-RX817 Di2 Rear Derailleur

Model: Shimano   |   Asin: B07XQN4B4R

Gravel cycling is a bit of an enigma. While it's mostly new to the scene, it manages to evoke nostalgic feelings that we don't really get from modern road cycling these days. Between wool jerseys, steel frames with drop bars, and a sense of adventure that doesn't stop when the tarmac ends, it manages to captivate us with an undeniable vintage aesthetic. With that said, it's not all about throwing new technology to the side, and Shimano proves it with the GRX RD-RX817 Di2 Rear Derailleur that brings electronic shifting to the gravel scene, built tough enough for life off road, but with silent, uninterrupted shifts that are precise and reliable regardless of the terrain ahead. Like you'll find through the rest of Shimano's GRX rear-derailleur line, the RX817 comes equipped with borrowed technology from the mountain bike world with Shadow clutch mechanism that adjusts chain tension to reduce dropped chains and keep your ride quiet through the rubble. Following in the footsteps of the revamped Dura-Ace and Ultegra groups, this GRX derailleur gets its Shadow cage treatment placing it closer to the frame and under the cassette keeping it out of harm's way and less likely to take the brunt of a driveside crash. This also allows the derailleur to move in a much more linear path allowing for shorter throws with less effort. The RX817 model comes ready to roll with a medium cage length, which accommodates both Shimano's 11-40t and 11-42t cassettes, allowing for a wide range gear ratio when paired with a double without the usual huge jumps between the cogs like on a 1x setup. Sticking to what the brand's customers know well, Shimano continues to use the Dura-Ace, Ultegra, and Tiagra designation with the GRX line, with this particular model falling under the Ultegra umbrella, which means it gets the usual materials and finishes that we expect from a groupset that's just one step from the top. Its weight, smoothness, and durability make it more than capable of racing agains...
