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

Serious road riders put in serious miles. Most of those miles occur in the daytime, when bright ambient conditions mean you need huge lumens numbers to be seen by motorists. But there's no reason a super-bright taillight can't look the part on the fastest road bikes. You invest in the best road bike technology--you deserve an equally fast taillight. Packing a huge punch with 250 lumens, the Flux 250R taillight is visible at more than 1 mile (1.5 km) in the brightest daytime conditions. Here in Morgan Hill, California we get those conditions all the time, this is the taillight we made for ourselves, and for you. - Designed to fit round and D-shaped seatposts. - Disco Flash mode: 250 lumens for 8:00 hours - Eco Flash mode: 25 lumens for 60:00 hours - Hybrid spherical lens and Fresnel lens over three high-power LEDs to send lumens for mile, or kilometers. - IPX7 waterproof means this light will be there when you need it, even in the hardest rain. - Includes 3 different size EPDM o-rings to fit a wide variety of seatposts. 2 o-rings included per size for spares. - Massive 1000mAh battery recharges via included micro USB cable in 2:15 hours. - Overmolded bezel for excellent side visibility. - Power Flash mode: 250 lumens for 8:00 hours - Steady High mode: 100 lumens for 3:00 hours - Steady Low mode: 25 lumens for 12:00 hours - Three CREE XBD 901 LEDs for maximum brightness and efficiency.

Splitting the difference between the previous Flux 800 and 900, the Flux 850 gets the game-changing Mode Shift found on the Flux 1250. This means there are three steady modes, all using both the wide and spot beams. Go from Steady Low to Steady High in a single push, without cycling through a flash mode. Press-and-hold for two seconds and you get into the secondary modes: Steady Flash to be seen in busy urban environments, Flash Mode for endless runtime, and two Flashlight modes with 10 and 20 hours of runtime for hanging around the campsite, or when you forget to charge your light and need to conserve the last few percent of battery life to get home. IPX7 waterproof means this light can survive being submerged 1 meter deep for 30 minutes. No, it's not meant for scuba diving. But is can handle anything you can throw at it on two wheels. - Sculpted double beam pattern uses separate optics for wide and spot beams to put light where you need it and maximizes every lumen. The result is a beam pattern that torch-style lights can't touch. - 1x CREE XP-L High Intensity LED plus 1x CREE XP-G LED. - Quick-release bar mount works on 22.2, 25.4, and 31.8mm bars to put the light above, below, or in front the stem to clear cables and computer mounts. - Extra bright side lights to give you 180-degree visibility to other cyclists and motorists. - 2600mAh Li-ion internal battery is USB rechargeable via included micro USB cable. - Depending on mode, up to an additional three hours of super-low output are available when listed runtimes expire.

Our Sport Hydration Drink Mix was created for a simple purpose—to replace the electrolytes lost in sweat and to provide a little bit of energy when working out, without offending your palate or gut. We initially created this drink because some of the world's best athletes needed better. Conventional sports drinks made them sick. They were undrinkable—too sweet, over-flavored, and didn't even replace what was lost in sweat—which defeated the whole purpose, like fighting thirst with more thirst. The best athletes needed something to safely hydrate, something to quench their thirst, and something to help them perform better. So with their help, we reimagined sports drinks, stripping down what used to be a neon-colored carnival to its bare essentials. In the process, we learned that simple wasn't just better for elite athletes, it was better for everyone who works hard and sweats. The result is a sports drink with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per liter), and only real fruit for flavor for a light and refreshing taste that you can drink all day. That's it—less sugar, the right electrolyte profile, and real fruit. So, if you've never met a sports drink you wanted to take home, your luck is about to change. Drink when thirsty and leaking like a busted fire hydrant. Don't drink while deep in the middle of a Netflix marathon session or sending emails (unless, you're also on your trainer). Meaning, if you haven't earned it, you don't deserve it.

Our Sport Superfuel Drink Mix was created for athletes who push so hard that they can't easily take in enough calories to perform at their best. For years, we've preached fueling with real food, like our famous rice cakes or Anytime Energy Bars. Why? Because traditional fueling gels and drinks use carbohydrates that break down too fast to tolerate, causing gastrointestinal distress. But, we get it—you can't always make or carry real food—you want power in a bottle. We've discovered the answer in a better carbohydrate (with a funny name) that digests steadily like real food does: Cluster Dextrin. One serving of Superfuel gives you 400 calories, powered by Cluster Dextrin, plus the electrolytes lost in sweat to fuel and hydrate your biggest days. We've tested this product for over 20 months with the world's greatest athletes, including Gold Medalist Triathlete Gwen Jorgensen and the EF Education First Pro Cycling team. It has allowed these athletes to drink their fuel on some of the longest and most intense events in the world when they can't eat real food without causing gastrointestinal distress. Use it when there's no time to chew. NON-GMO, GLUTEN FREE, DAIRY FREE, KOSHER, VEGAN
