The Speedco M2 Junior Cruiser alloy frames are aesthetically designed to replicate the Speedco M2 Youth models. 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.
