Tough, aggressive and lightweight, Dyna-Sys11 11-speed SLX rear derailleur uses revolutionary features from XT and XTR at an affordable price point. Shimano's Direct Mount compatible Rear Derailleur system gives more space around the rear frame dropout resulting in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axle sizes and move suspension pivots. Shadow Dyna-Sys11 11-speed rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design. The Shadow features a super low profile design that reduces the risk of damage from trail side hazards. The shadow plus chain stabilizer tension can easily be adjusted externally via a hex key. Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining a more stable drive and shifting. This can be switched off to remove the wheel. Direct cable routing prevents snagging from any trailside hazards. Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails, whilst high rigidity wide outer links brace the pulley body to increase pivot joint rigidity resulting in a crisp shift.

The Park Tool DAG2.2 Derailleur Hanger Alignment Gauge can help solve a multitude of derailleur shifting problems, most notably with index shifting systems. Updated over the longstanding DAG-1, the DAG-2.2 utilises a longer measuring pointer, longer threaded stud and a longer, narrower alignment boss to fit a wider variety of bikes. This tool is extremely steady in operation and is simple to use. The tool threads directly into the derailleur hanger. The gauge bar holds a gauge which marks the distance to the wheel. The gauge then is rotated with the wheel to the 3, 6, 9, and 12 o clock positions, noting any differences in measurements. The alignment of the derailleur hanger is accomplished by applying pressure to the tool s arm. The results can be checked instantly. The DAG-2.2 is made of heavy-gauge steel and is chrome plated for long shop life.
Quick and responsive mechanical shifting, the Shimano Ultegra R8000 11-Speed Rear Derailleur works to give you quick, accurate shifts and excellent drivetrain efficiency.The derailleur features a lightweight aluminium pulley cage that has been manufactured to provide you with the integral strength to shift with precision and accuracy whilst under load. With a wide link design that gives quick and accurate shifting, this derailleur benefits from a low, aerodynamic profile that reduces the risk of damage in a crash.Low profile shadow design constructionWide outer link platesLightweight aluminium pulley cageSS Cage: Compatible with 11-25T Up To 11-30TGS Cage: Compatible with 11-28T Up To 11-34TWeight: 200g (SS Type), 210g (GS Type)
An essential tool for measuring and straightening off-kilter hangers, the Park Tool derailleur hanger alignment tool has improved upon its predecessor, the DAG-2, with increased strength, tighter tolerances for greater accuracy and improved clearance and reach for a wider range of frame/hanger combinations. Adjustable to allow you to work on wheels ranging from 20" to 29" +, the heavy gauge steel and chrome plated Park Tool DAG-2.2 will also fit Shimano Direct Mount hangers, making it a fantastically versatile, must-have tool for anyone serious about maintaining their bike.
