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. At the heart of the Pioneer Power Meter System are two streamlined strain gauge monitors that can detect the slightest tangent and radial force direction as power is applied to the crank arms. 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

Campagnolo is all about drivetrain evolution, and their Chorus Crankset proves it. The full-carbon cranks and 4-arm spider feature a unified bolt pattern that allows for all three chainring standards. This design incorporates an 8-bolt pattern with a spider arm that not only holds the chainring in place by way of the bolt, but also supports the chainring to increase system rigidity. The crank arms and spider are hollow for maximum stiffness and minimal weight. The integrated Ultra-Torque spindle joins the crankset together via a toothed Hirth joint in the center. - Chainring BCD: Campagnolo 146 Asymmetric, Campagnolo 112 Asymmetric
Campagnolo's incredible Record Ultra-Torque Crankset sports a unique, integrated spindle that joins the two sides of the crankset together via a toothed Hirth joint in the center.

Wolf Tooth's CAMO stands for Chainline and Material Optimization. Available in various chainlines and spider configurations, CAMO spiders allow the use of previously unavailable chainring styles, materials, and chainlines in a lightweight, modular, and customizable package. These spiders are for use with the RaceFace cranksets that have removable Cinch spiders/chainrings and are only compatible with CAMO rings and bolts. Three different chainline options are available. The number and letter refer to the mm offset and direction from the mounting face to the centerline of the teeth: - M8 (minus 8mm - dished toward the frame): For 49mm chainline, used with GXP and long-spindle BB30 cranks. Designed for bikes with 135mm QR, 142mm thru axle, and some 148mm bikes. - M5 (minus 5mm - dished toward the frame): For 52mm chainline (Boost) - P2 (plus 2mm - dished outward away from the frame): For fat bikes that have 190/197 rear spacing but use a 100mm-spindle crank
- Aluminum Hollowtech-II (HT8) crank-arm to BB-spindle Mounting Bolt - Bolt: only one needed for non-drive side

Surly's Offset Double Crankset is designed specifically for bikes running very large tires and rims, such as Surly's Moonlander and/or Pugsley. The offset helps prevent chain rub on the tire. The crank is made of forged and machined 7075 aluminum, is 9- and 10-speed compatible and comes with 22- and 36-tooth 5-bolt chainrings. A precision Enduro bearing-equipped English-thread bottom bracket is included, so this versatile crankset is ready to spin.
This OD Crank Single Speed Spacer Kit gets your Surly OD Crank ready to run as a single. Indluces chainring bolts and spacers. Just add chainring (sold separately).
Surly designed the O.D. crankset to offer frame and tire clearance while maintaining a reasonable q-factor (pedal stance). Maximizing the distance between the chain and the tire is important on fat bikes such as the Pugsley and Moonlander, or if you're running really big tires and rims on some other bike (like our new Krampus, for example). With normal cranks, wide tires on wide rims can rub the chain when in the lowest, or farthest-inboard, gear combinations. Like the MWOD crank, the O.D. crank doesn't just add a longer spindle to move the rings outboard. Rather, it does away with the big ring of a standard triple and moves the middle and granny rings to the outer and middle positions. This effectively moves the rings outboard without moving the arms outboard too. The O.D. is a simple, dedicated version of this idea. Neato! Forged of 7000 series T6 aluminum, the O.D. crank is a 2-piece, with spindle embedded inextricably in the drive side arm. It's a dedicated 2x, although its chainline is outboard a bit compared to standard mountain cranks, and it is 9 and 10 speed compatible. The 132mm, PF41 bottom bracket O.D. crank is what goes on the Ice Cream Truck bikes, so if you've got that setup, that's your crank. Surly also offers 33t and 20t rings separately. These chain rings are designed to shift best in specific combinations….change to a 39/22t, for example, and your shifting will suffer. The bearings on which they spin are also worth mentioning: Surly upgraded the bearings on these and the Mr. Whirly and MWOD cranksets to aftermarket Enduro bearings with double labyrinth seals, meaning they actively shed and stay clean of dust, muck, and grime, even in wet and muddy climates.
