For 2017, Shimano uses their shadow design, for a thinner assembly construction to offer a more streamlined, integrated fit.

SHIMANO XT RD-M8000 Rear Derailleur

Model: Shimano   |    Mpn: IRDM8000   |    PartNumber: IRDM8000   |   Asin: B012APZJAI

The big news for Deore XT this year is its new M8000 11-speed drivetrain. This, of course, isn't the only upgrade for the most trusted drivetrain in cycling. The new derailleur also boasts an easy-to-adjust chain stabilizer and a new Shadow design with optimized slant for more stable positions in any gear. Shimano claims that shifting requires 20% less effort with the new design, and less is good.If you're still using traditional hanger, the RD-M8000 comes with a link installed so it's backward-compatible. The direct mount, however, eliminates the need for the link, effectively reducing flex, wear, and weight -- all good things to mountain bikers. On compatible frames, the system also allows easier wheel changes with thru axles. Another big change is the stabilizer switch trickled down from XTR and Saint derailleurs.When engaged, this switch helps to eliminate chain slap and dropped chains by increasing spring tension. This is a valuable option for suspension systems that require chainstays and pivots located close to the rear derailleur. The RD-M8000 retains all the last models improvements, including the direct cable path. Your shift housing can enter the stop on the derailleur without the traditional loop of excess housing that often was the victim of contamination and a source of poor performance.Shimano uses tried-and-true aluminum components in the XT derailleurs. All of the knuckles, linkage plates, and cage sides are made from it. So while it may lack the wow factor of the carbon fiber-laden XTR Shadow, it's more affordable, and if you've been running XT derailleurs as long as we have, you'll know that you'll get plenty of mileage out of it.

SHIMANO Ultegra RD-RX800 Rear Derailleur

Model: Shimano   |   Asin: B07JMZ3TWM

Outfit your all-road or CX bike with Shimano's Ultegra RD-RX800 Rear Derailleur and enjoy increased chain tension thanks to its mountain bike technology offering better chain management and less noise over rougher roads and gravel. Just like we're accustomed to on its mountain rear derailleurs, a flip of the lever engages and disengages the clutch. 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. This is Shimano's first rear derailleur featuring a clutch for drop bar bikes and since it works with both 1x and 2x setups, we feel it's a must-have for gravel and 'cross bikes. Following in the footsteps of the revamped Dura-Ace and Ultegra groups, this RX 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. It comes in one cage length, long, which accommodates an 11-34t cassette 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. Sitting under the Ultegra umbrella 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 against the competition on course, or the sun to your campsite for the night on a bikepacking trip.

Features

  • Material: alloy
  • Cage Length: Long
  • Capacity: 39t
  • Cassette Range: 11 - 34t

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

SRAM NX Eagle 12-Speed Rear Derailleur

Model: SRAM   |   Asin: B07J3TWFWF

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.

Features

  • Material: steel, aluminum
  • Pull Type: X-Actuation
  • Cage Length: Long
  • Cassette Range: 10 - 50t, 11 - 50t
  • Gearing: 12-speed

CeramicSpeed Oversized Pulley Wheel System - Coated

Model: CeramicSpeed   |   Asin: B07JBLVCBC

Dropping drivetrain drag improves the performance of your road bike and it doesn't matter if it's a lightweight climbing bike or an aero TT speedster. So, if you want to go faster with fewer watts required to do so, upgrade your derailleur with the Coated Oversized Pulley Wheel System from CeramicSpeed and enjoy a ride that's faster by ridding your drivetrain of frictional drag. It's harder to quantify frictional losses compared to say, aero data in the wind tunnel or grams on a scale, but there's a reason why you see these setups of the bikes on the pros as they appreciate saving some wattage expenditure, and the coated ceramic bearings and the large diameter derailleur pulleys offer a one-two punch against drag. On many of the GC leader's bikes, and even more prevalent on those important TT stages, you'll find CeramicSpeed's pulley wheels and cages, whether that's sponsor correct or not, as they know that going as fast as they can depend upon it. Now, you too can enjoy the same benefits the pros count on in training and racing when reducing drivetrain friction to a minimum is required. The remarkable cage and pulley systems are developed and hand assembled in Denmark. The products are all tested in the lab and with feedback from professional riders and mechanics to ensure it works great in the field and installs easily. CeramicSpeed claims the OSPW System is the fastest pulley system in the world providing an energy savings of around 1. 6 watts for SRAM and 2. 4 watts for Shimano over their standard pulleys. As a bonus, CeramicSpeed's testing shows that these pulleys last anywhere from 3-5 times longer than stock. This version, with coated bearings, increases durability by adding a special treatment to the bearing races that also further reduces friction. We have models for Shimano, Campagnolo, and SRAM eTap rear derailleurs. The OSPW System for SRAM features two 17-tooth aluminum pulley wheels with the accommodating cage made from nylon and carbon fiber and...
