Our patented ANGi sensor calls for help when you can’t. In fact, it’s the first device to protect you before, during, and after a crash. It does this through a pairing with our Specialized Ride App for iOS or Android devices. And if it detects a crash, it commences a countdown that, if you’re ok, you can stop and keep riding. If, however, ANGi determines that you’re in need of help, it’ll send an alert to your selected contacts with your last known GPS coordinates and a message that you’re in need of help. What about if you’re out of service coverage? ANGi has a plan for that. Just set your estimated ride time before you head out when you know that your ride will take you out of range. All you need is an active data signal when you start your session. And if you haven’t completed your ride within that time frame, ANGi will send a notification to your contacts with your last uploaded location. - ANGi is a ride tracker, crash detector, and safety beacon. - Includes a one-year subscription to Specialized Ride Premium app. - Detects and reports potentially dangerous helmet impacts to the Specialized Ride app, which notifies your emergency contacts and sends them your most recent GPS coordinates. - Additional premium features include start ride notifications and ride-time alerts. - Attaches to Specialized ANGi-ready helmets. - Approximate six months' battery life on a 2032 coin cell battery. - Weight: 10 grams w/ battery - Two-year sensor warranty

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.
