Eagerly anticipated after the impressive performance of the first generation Sensor, the 2015 GT Sensor Pro Carbon Complete Bike is the ultimate form of the all new Sensor platform. Rendered in top shelf carbon and sporting a revised independent 130mm suspension design riding on 27. 5 inch wheels, plus a premium build kit, the Sensor Pro Carbon is a bike that will completely redefine your expectations of mid travel trail bikes. The Sensor Pro's frame is a marvel of modern mountain bicycle engineering. First thing to observe is the FOC or Force Optimized Construction Ultra carbon itself. The Ultra version of GT's FOC carbon is its most advanced, an ultra high modulus weave of premium carbon that's so strong it could be layered almost as thin as a pro level road bike frame. Relentless testing of different directional carbon layups resulted in the perfect balance of lateral rigidity, impact resilience, and minimal weight. Before it gets painted, the Sensor's chassis is a particularly beautiful thing to behold, its complex carbon structures and weaves revealed and making visible the engineers' attention to detail. On the trail, however, the results speak for themselves it's one of the most confident, capable, and responsive frames you'll ever ride. Helping out in this regard is GT's revolutionary Independent Drivetrain suspension platform. The idea of isolating the drivetrain so that it's not affected by suspension movement is nothing new, but GT's approach is, and it works really, really well. The crankset and the rest of the drivetrain make their home entirely on the rear triangle, unlike many designs that put the crank on the mainframe and the rest of the drivetrain parts on the rear triangle. The problem with this is suspension compression that occurs with pedaling force, robbing you of efficiency. It's simpler to build bikes this way but it works. However, you make a sacrifice in responsiveness. Sprinting or out of saddle climbing on the Sensor is rewarde...
