Our M2 line of alloy frames are aesthetically designed to replicate our Flagship model, the Velox Carbon. The custom 7005 series alloy tubeset on the M2 frames are heat treated and double butted for weight reduction and increased strength. The down-tube on the M2 line is oversized and tapered slightly throughout the sizes to enhance response and insure that riders of all sizes benefit from the maximum rigidity for their body weight. The chain-stay width follows suit as these bikes were built to sprint, and peak performance out of the gate and corners under high power output is top priority in the M2. Lastly, an integrated chain tensioner system is seamless throughout the 16 sizes in the M2 line and will keep the rear wheel locked in under the highest wattage output you can only dream of. Do you have what it takes to put the most responsive alloy bike you_ã_ve ever ridden through it_ã_s proper paces?
