The Insight series fits into the Performance Hybrid category. Taking the best from both the mountain and road worlds, The Performance Hybrid combines their elements to create the ultimate machine. Larger-diameter 700c wheels offer an efficient platform for this nimble, lightweight bike that’s suitable for commuting, training or simply a weekend ride. Our Insight series also embraces performance factors valued by today’s training racers and charity riders.

The 2014 Insight STI-1 is our single speed performance hybrid aimed to please those who commute, train, exercise, or are simply looking for a smooth riding bike for recreation. The jewel of the bike is the Insight 6061-T6 Butted Aluminum Performance Hybrid frame with a formed/hooded top tube, an integrated headtube, and vertically compliant stays (VCS).

Fit specifically for the frame is the Insight Integrated Ferous Aero Hi-Ten Steel straight blade fork keeping your ride smooth, stable and precise. SR Suntour provides a 42t crankset with a double ring guard on either side to keep your chain inline and engaged at all times. Tektro linear pull brakes provide plenty of stopping power in all conditions to keep you out of harm’s way. 32h Equation R23 Doublewall rims provide a solid structured wheel capable of all day rides.

The cockpit is made up of proprietary Diamondback alloy design with an oversized 31.8mm low rise alloy handlebar and 3D Forged 7° stem to give the appropriate rise for maximum steering control and comfort.

A DB Performance Hybrid saddle with gel sits atop a 27.2mm alloy micro adjust seat post offering an exceptionally comfortable ride whether it’s for your next cause ride or simply around the block.

The 2014 Diamondback Insight STI-1 is grey and comes in 4 sizes: SM (16"), M (18"), LG (20"), XL (22").
