Specialized Power Cranks - Shimano Ultegra Upgrade Kit
$525.00
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 Ultegra Upgrade Kit are no exception. With our lightweight power sensors on a Shimano Ultegra 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 8000 generation Ultegra left-side power measurement. - Right crankarm and spider NOT included. - Available in 170-175mm crankarm lengths.

Pioneer Power Meter Upgrade Kit
$499.99 $799.99 38% Off
Dual Leg Installation Kit for DURA-ACE 9000, ULTEGRA 6800, and Campagnolo Potenza 11 Cranksets 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. Installation and delivery take approximately 7-to-10 business days. 12-Point force and force direction measurement: Pioneer has created the first, and only, power meter that measures power output and pedaling stroke efficiency for each individual leg, in real time, so you can analyze and adjust your technique while you ride. 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. Monitor force vectors and pedaling efficiency in real time: When used with Pioneer Cycle Computers, Pioneer has created the only Power Meter to measure force and direction of force in 12 locations – or every 30 degrees – while pedaling. When used with a Pioneer Cycle Computer, these measurements are graphically displayed as force vectors. These force vectors allow you to analyze the unique characteristics of your pedal stroke and calculate pedaling efficiency. And you can monitor it all in real-time on a Pioneer Cycle Computer, while you ride. The industry’s first accurate torque vector measurements: When it comes to measuring torque vectors, there’s nothing approximate about it. Pioneer has designed the only Power Meter to provide precise torque vector readings at 12 points of every pedal stroke. These can be monitored in real-time on a Pioneer Cycle Computer. The industry’s first accurate torque vector measurements: When it comes to measuring torque vectors, there’s nothing approximate about it. Pioneer has designed the only Power Meter to provide precise torque vector readings at 12 points of every pedal stroke. These can be monitored in real-time on a Pioneer Cycle Computer. Compatible with ANT+ Cycle Computers: ANT+™ is a low-powered (2.4GHz range) wireless communications standard used by most cycle computer brands. The Pioneer Power Meter can easily pair with ANT+ compatible cycle computers and display power measurements that are available on that computer. For the full range of never-been-seen-before data including force vectors, torque vector, and other measurements, it must be paired with the Pioneer Cycle Computer. Post-ride data like you’ve never seen before: The ultimate training tools. Cyclo-Sphere for PC and supporting Cyclo-Sphere Mobile App let you analyze every moment of every ride. Simply upload your ride data to Cyclo-Sphere to view total power, power balance, force and torque vector charts, pedaling efficiency, heart rate, speed, cadence, distance, altitude, temperature, and much, much more. Cyclo-Sphere Mobile App provides quick access to your Workout List with a powerful Segment Compare feature that allows you to choose where and when you want to challenge yourself the most. Both Cyclo-Sphere PC and Cyclo-Sphere Mobile App are complimentary with your Pioneer Cycle Computer.

The All-Mountain Guide is a great choice for 5-6" travel bikes when used with the latest tensioned rear derailleurs or on its own for shorter-travel trail bikes or hardtails that require bash protection. The contact-free, "upper-only" chain retention means the All-Mountain Guide will be virtually silent and completely drag-free when pedaling. The patented integrated skid will protect your crank and chainring and prevent the chain from ever contacting and potentially damaging your expensive frame. - Perfect for "clutched" 1x10 and 1x11 drivetrains, as well as those using chain-retaining rings (like our Wave Ring) - New nylon integrated skid protects chainrings and glides over rocks and obstacles - Tracked and grooved upper guide / backplate interface increases stiffness and eases installation - New co-molded "TR" upper guide with softer durometer interior for silent guidance - Available in 28-32t and 32-38t sizing - All install and adjustment operations possible with just a single 4mm HEX wrench. - Compatible with chainlines 49mm and wider
