Power to the people! Add the Pioneer Power meter to your existing Shimano crank. Pioneer's crankset-based power meters are simply some of the best power-monitoring systems on the planet, and the Upgrade Kit gives you the chance to add it to your existing crankset.

This proprietary system detects the amount and the direction of force at 12 different points in each pedaling stroke for each leg, and allows you to fine tune your pedaling to find race-winning form. The Pioneer Power Meter Installation Kit comes with everything you need to package and send your existing Shimano crank to Pioneer for professional installation and calibration. - Compatible with Shimano Dura-Ace 9000 or Ultegra 6800 (Right Side Cranks Only) - Compatible Crank-arm Lengths: 165, 167.5, 170, 172.5, 175, 177.5, 180mm - Fully Integrated Strain Gauge for force measurement - Easy connectivity with ANT+ compatible Cycle Computers - HDPower Metrics when connected to Pioneer Cycle Computers - Lightweight Sensor Only 40 grams

This one takes all your trail dreams, from XC to enduro, all the way to eleven. SRAM's XX1 rear derailleur packs a massive amount of technology into its compact, lightweight body.

This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.
