You have a lot of choices when choosing a crankset, and your choice says a lot about your personal style. SRAM designed the X01 Eagle crankset for riders who feel most stylish when they stand on top of the podium. This is a completely reengineered design, employing their proprietary CARBON TUNED lay-up technology. The new X01 Eagle is SRAM's best, toughest, and most aggressive Trail and Enduro crankset thanks to DUB technology, which features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination—and define a new measure of durability. If you’re into that kind of thing. - DUB technology delivers the strongest, stiffest, lightest crankset available - SRAM CARBON TUNED crank technology provides extreme stiffness and light weight - Chainring technology is designed specifically for Eagle chains and drivetrains - The X-SYNC 2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability - Chainline: 76.5mm
- The carbon crank arms are completely hollow with all unnecessary material being removed from the centre core - no internal aluminum spine - Industry standard 30mm spindle with Cinch spline interface. The spindle is CNC machined from a newly commercialized aluminum 'super alloy' that is 20% stronger than 7050 alloy (the alloy commonly used in this application) - Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments - The interchangeable spindle option of the Cinch system allows you to use the same crankset with 68/73mm and 83mm frames
Trail riding can be tough on your gear. The ends of your carbon cranks can take a lot of abuse as the trail rushes underneath you and your bike.

Whether you're looking to take your training to the next level or you simply want a better way to measure energy expenditure, a power meter is your best bet. And the Power Cranks 105 Upgrade Kit are no exception. With our lightweight power sensors on a Shimano 105 crankarm, it's the perfect way to enter the power meter game. The development of Power Cranks began with our Human Performance Team looking at riders in realistic scenarios on the bike. Historically, power meters have been validated by two different methods—one is by measuring the produced torque by applying a static, linear load to a crankarm or chainring, while the second uses a power generating motor to pedal the bike. Well, cycling is neither static nor linear, and humans apply power much differently than a machine. So, we found that neither of these methods answers the 'real-world' accuracy question. To get the best test for accuracy, in all types of riding scenarios, we built our own cycling treadmill, the WinMill, to measure power output to a known truth. This new benchmark lets us evaluate accuracy under all riding conditions—seated versus standing, various power and cadence levels, different weights, and a myriad of gear. This data acquisition process is our gold-standard for testing power meters, and through our testing and external validation from the Locomotion Lab in Boulder, Colorado, Power Cranks have been proven to have the highest accuracy in real-world scenarios (+/- 1.5%). The Power Cranks are also easy to live with, with class-leading temperature compensation firmware and waterproof enclosures. Calibration is only required during seasonal-type fluctuations in temperature, and the included wrench makes battery swaps a breeze. - +/- 1.5% real-world accuracy tested on the WinMill and validated by the Locomotion Lab in Boulder, CO. - Works with ANT+ and Bluetooth devices. - Easy set-up and diagnostics with the Specialized Power app. (iOS and Android versions available). - Shimano 5800 generation 105 left-side power measurement. - Right crankarm and spider NOT included. - Available in 170-175mm crankarm lengths.

The new Record 12x2 Speed crankset: a new hole-free design for the right-hand crank that optimizes aerodynamics. The new carbon fiber Record 12x2 Speed crankset with unidirectional finishing guarantees continuity with the finishing of the entire groupset, whilst maintaining the Ultra-Torque bracket system on the steel axle to ensure perfect transmission of power. The new Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters without affecting the Q factor that remains constant at 145.5 millimeters. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) enable reducing the weight through greater use of carbon fiber. There are eight fixing screws for increased structural stiffness. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.
