Cranksets

Consistency and accuracy in training lead to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq power meters using Quarq technology, measure power at the crankset spider. This the best place on the bike to measure power because all of your pedaling effort flows directly through the spider and it can be measured with great precision. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA RS Power Meter Crankset accurate to within 1.5% (strain gauges benefit from accurate temperature). Plus the ELSA RS is specifically designed to match Shimano's 4-bolt Hollowglide chainrings for a seamless junction between ring and chassis. Quarq's Exogram Hollow Carbon crankarms deliver every watt to the road while keeping the weight incredibly low. ANT+ technology lets you hook up your desired compatible head unit, the LED indicator flashes when the power meter is on, and the single, easily-replaced CR2032 battery lasts for up to 300 hours of ride time. - Compatible with 11-speed Shimano chainrings (Dura-Ace, Ultegra, and 105) - Chainrings and bottom bracket are sold separately - Requires ANT+ head unit (sold separately) - 616 grams (GXP, 172.5mm) - Battery life: 300 hours

In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains. - Single-ring drivetrain simplifies functionality - 48T and 50T variants have fully integrated power into a direct mount aero chainring - 36-46T variants have spider-based power - Chainrings can be easily changed without requiring recalibration of the power meter - Power readings are accurate within +/-1.5% and aren't affected by climate conditions during a ride - Power balance measures left and right legs separately - SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control - Laser-etched chainring finish is more durable - DUB bottom bracket adds durability and simplicity - Non-aero chainrings can be installed with a single tool, making gearing changes a breeze - Bottom bracket not included - BB Compatibility: All SRAM Road DUB BBs - BB Spindle Interface: DUB - Chainring material: Aluminum - Crank arm material: Carbon - Power Meter Type: ANT+ and BLE

The SRAM RED AXS power meter breaks with tradition — and breaks through to new levels of performance. SRAM reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. They also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. These power meters are also designed with Quarq's premier DZero power measurement technology fully integrated into the crankset.

No matter your skill level or experience on the bike, there's no better way to enhance your training and racing performance than by riding with a power meter. Lucky for you, Specialized has combined their incredibly light and stiff carbon fiber S-Works road cranks with dual-sided power measurement, making it the lightest (440g/172.5mm) and most accurate power meter available. The development of Power Cranks began with Specialized's 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, they found that neither of these methods answer the "real-world" accuracy question. To get the best test for accuracy, in all types of riding scenarios, Specialized built their own cycling treadmill, the WinMill, to measure power output to a known truth. This new benchmark lets them 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 their gold-standard for testing power meters, and through their 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 Dual-Sided S-Works Power Cranks utilize separate strain gauge systems to individually measure the effort produced by each leg. This maximizes the accuracy of your total power numbers, plus it helps you to better understand your performance as fatigue increases and when you're recovering from injury. And with class-leading temperature compensation firmware and waterproof enclosures, Power Cranks are easy to live with. 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. - Independent, dual-leg power measurement. - Works with ANT+ and Bluetooth devices. - Easy set-up and diagnostics with the Specialized Power app. (iOS and Android versions available). - Hollow carbon crankarms, carbon spider, and oversized alloy spindle offer superior stiffness and lighter weight than the competition—440 grams for 172.5mm crankarm length. - Fits Specialized road frames with OSBB or PF30 bottom bracket shell, as well as most BB30 road frames. - 110 BCD carbon spider (also compatible with 130 BCD carbon spider—sold separately). - Compatible with Shimano and SRAM drivetrains. Chainrings are sold separately. Use only with Specialized/Praxis chainrings 06217-1702 (52/36T) and 06218-1713 (50/34T). - Available in 165-180mm crankarm lengths.

The crankset is the heart of your bicycle and where you’ll find the SRAM RED Quarq power meter. The sole job of the crankset is to convert the effort from both legs to forward motion.

The new Super Record 12x2 Speed crankset: an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic “super design." The new carbon fiber Super Record 12x2 Speed crankset has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drivetrain. The new Super 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, which remains constant at 145.5 millimeters thanks to the new hand crank design. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. 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) combined with the eight fixing screws, optimize weight and stiffness through the increased use of carbon fiber. 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.
