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. And for all of you Dura-Ace fans out there, we've combined our extremely light power sensors with a Shimano Dura-Ace crankset to give you the most accurate and precise power meter available. 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 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) - Available in 170-175mm crankarm lengths - All models include 52/36T chainrings

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.

First, Garmin invented wrist-worn portable navigation. Then, with the D2 Bravo pilot watch, we took the idea a step further — combining even more capability and features in an elegant design that is lighter, thinner, more connected and simpler to use in today’s busy cockpit environments. - Thinner, lighter, more evolved GPS pilot watch design - Features METAR screen for the latest aviation weather information - Dedicated Direct-to and Nearest buttons enabled by a worldwide airport database - Scratch-resistant optical sapphire lens and crisp color display that's customizable with Connect IQ apps - Baro-adjustable altimeter, HSI, Zulu/UTC time reference, various timers and alerts plus wireless control for VIRB® cameras

Go from one-sided to dual-sided power measurement with Garmin's Vector 2S Upgrade Pedal. With your standard 2S system (sold separately) you only have power data from your left leg, which leaves the possibility of unknown discrepancies between your left and right sides. Injuries, natural imbalances, and other factors that leave one side of your body less powerful than the other are common. By measuring power from both legs, you get a much more accurate picture of what you're doing and how to improve on any asymmetry you might have.

Pioneer's Shimano Dura Ace 9000 Power Meter is a revolutionary power meter that attaches stealthily to the left crankarm. The Dura Ace 9000 left crank arm meter allows every rider power-based (also called watt-based) training performance, allowing you to fine-tune your pedaling to find race-winning form without breaking the bank. With advanced technology accurate to +/- 2%, ANT+ transmitting, active temperature compensation, and a mere 22 grams of weight, the Pioneer power meter is perfect for any cyclist. Additionally, installation is fast, simple, and clean with zero wires, magnets, or zip ties. If you find yourself addicted to the data and crave more, upgrade kits that retroactively add drive-side power are available (sold separately).
