Shimano SLX M7000 Shadow Plus 11 Speed Rear Derailleur Rear Derailleurs
  • £76.99

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.

Park Tool DAG2.2 - Derailleur Hanger Alignment Gauge
  • £76.49
  • RRP £85.00
  • Saving you £10

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.
