The SRAM Rival 22 11 Speed Rear Derailleur may be a touch heavier than its Force and Red siblings, but it sacrifices nothing when it comes down to performance, dependability, or durability. Its competition-proven design ensures exacting shifting no matter what the conditions. SRAM’s Exact Actuation technology is actually a hand-me-down from its mountain bike groupsets. It designates a 1:1 relationship between shifter cable travel and derailleur movement. This simple index shifting helps to simplify balancing derailleur hanger design, tight cog spacing and cable tension to ensure fast, efficient shifting. The derailleur moves through the entire range of shifting via a 3mm movement from gear to gear. The derailleur was constructed from aluminum inner and outer cages as well as b-knuckle. Although these are slightly heavier than the titanium hardware and carbon cages used in the Force and Red Groups, they retain structural integrity and ensure durability. The SRAM Rival 22 11-Speed Rear Derailleur is available in both a Short and Medium cage version. The Short cage has a maximum rear cog capacity of 28tooth while the Medium is able to work with a 32tooth cog. It is available in the color Grey.
Type 2 adds the Roller Bearing Clutch to a normal X0 derailleur to deliver maximum drivetrain stability, even through rough terrain. This clutch eliminates bounce and chain slap without sacrificing precision. Clutch is self-lubricating, maintenance free, uses needle bearings, and comes factory calibrated from SRAM.
The DURA-ACE 9100 Front Derailleur is easy to set up, has several convenient features, and provides superior performance. When setting up the 9100, riders will immediately notice that there are more cable routing options, a new top-routed cable entry, and that it features an integrated cable tension adjustment, which eliminates the need for a barrel adjustment. It also features a more natural front shift lever stroke, and an increased ergonomic power curve. The DURA-ACE 9100 weighs only 69g, and is equipped to allow for shorter chainstays with 135mm O.L.D.Features: New top-routed cable entry with housing that feeds directly into the derailleur body Multiple cable routing options Integrated cable tension adjustment, which eliminates the need for barrel adjustment Lightweight at just 69g Allows for shorter chainstays with 135mm O.L.D.

2×11= 9000. The Shimano Dura-Ace 9001 11-speed shifter set provides superior control for multiple riding styles. From the smaller volume hood and carbon brake lever, to the Vivid Index Shifting that delivers a defined click engagement with only light effort, the 9000 series is superb. <p>The new Shimano inner cable reduces sliding resistance to achieve lighter and quicker shifting and braking operation. Additionally, internal cable routing delivers lighter steering action and a clean handlebar area. Only 365 grams for the set.</p>
New Ultegra’s striking wide-link design main body creates rigid pivots that create a foundation for precise shifts. Additionally, the new body and cage design accommodates a 28 tooth large cog so the mountain stages can be attacked with confidence. .
The Shimano XT Shadow Rear Derailleur’s super low-profile design improves durability and reduces the odds of damage in a narrow passage. Single tension construction prevents the derailleur from hitting the chain on rough terrain, and direct routing reduces snags. The XT Shadow’s strong return spring allows for precise shifting.
Product Features
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 has always been the groupset of choice for riders who prefer bombproof durability over the latest in carbon. But, what those riders also know is that Ultegra is always privy to the latest advancements in the venerable Dura-Ace group. The Ultegra 6800 is no exception. Taking its cues from the Dura-Ace 9000, 11-speed group, the STI shifters see a significant leaning toward the engineering and aesthetic of its older sibling. The bulkiness of the old Ultegra shifters has been replaced with a slimmer, dual-compound rubber composite hood and streamlined carbon fiber levers. This means improved grip on the hoods as well as more reliable shifting. Additionally, they now have 10mm of reach adjustment to ensure the perfect fit for most hand sizes. As far as the shifting, Ultegra has upped Shimano’s “Rider-Tuned” philosophy a notch. To begin with, the lever stroke has been shortened by almost 13%. This means that you won’t have to push as far to make the gear change. Using its Vivid Index Technology, the effort to downshift is now as smooth as to move the gears up. This is done not only through careful design of the Ultegra 6800 STI mechanism itself, but also through the incorporation of Shimano’s polymer-coated shifter cables that reduce drag.
