SRM SRAM 975 BB30 Power Meters

SRAM 975 BB30

The merits of the BB30 integrated bottom bracket design are many. And combine the added stiffness, simplicity, and ankle clearance of the BB30 with the accuracy and reliability of a SRM PowerMeter and you've got one heck-of-a crankset in this, the SRM SRAM 975 BB30 PowerMeter System. The SRM SRAM 975 BB30 PowerMeter uses unidirectional carbon fiber crankarms for solid power transmission. They're built just like SRAM's Red cranks save for having the separate spider, which houses the SRM power sensing internals. Red level chainrings round out the package. A hard anodized finish on the alloy rings complements the Powerglide ramp and pin design for effortless shifting and also adds durability. Perhaps the most important consideration in favor of a crank-based SRM PowerMeter is the fact that no matter the terrain facing you on race day, you'll have the freedom to choose any set of wheels that suit.The crankset comes with a small frame-mounted bracket impregnated with a magnet. For those of you familiar with the wired generation of the SRM, you'll note that it looks an awful lot like the head of a sensor cable. The purpose of this magnet is to read cadence, and you must install it -- even if you don't care about cadence. Why? It's because Power = Torque x Cadence, so with no cadence reading you get no power reading. The SRM SRAM 975 BB30 Wireless PowerMeter System comes in the crank length of your choosing -- 170mm, 172.5mm, or 175mm, and it will have a standard 39/53 chainring configuration. The SRM system employs the ANT+ 2.4ghz wireless transmission technology. So not only will it free you from the distraction of having wires all over your bike, but you'll have the freedom to use any ANT+ compatible CPU/receiver. We offer four CPU options that will sync perfectly with your crank to accurately track your power data:The SRM PowerControl 7 is the latest evolution of the benchmark SRM PowerControl. There's a reason that more Pro cyclists use SRM power equipment than any other -- absolute reliability. The PowerControl 7 offers a new button configuration, under the display, that allows the unit to be narrower than older versions. This makes it ideal for use between aero bars. At any given time you'll be able to read six different bits of information on the new display. And like the PowerControl VI, it reads altitude and temperature to correlate along with your power, speed, distance, and kilojoule data. It also has a motion sensing start/stop function. The PowerControl 7 is downloadable via an integrated mini-USB interface and comes with an oversized handlebar mount, a Suunto speed pod, and a Suunto heart rate chest transmitter strap. It can be used with the included SRMWin software and also with Training Peaks, WKO+, and other power software.The Garmin Edge 800 GPS is for those addicted to touchscreen technology. It has nearly all of the same functions as their Edge 705, but it comes with the convenience and ease of a waterproof, rugged 2.6
