The Speedco M2 alloy frame line is back like it never left, revisited and updated. Featuring a custom 6066 series alloy tubeset, double butted and heat treated for weight reduction and increased strength. The down-tube 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. Internally routed through the frame for a clean aesthetic.Pro Spec:1-1/8" to 1.5" tapered head tube27.2mm seat postPress-fit BB86 BB shellUniversal 10/15/20mm dropoutIntegrated chain tensionerWorks with post mount disk brakes and 120mm disksIncluded with Pro Model:Axle blocks 10/15/20mmChain tension screws/nutsInternal cable routing hardwareDisc brake mount for 10 & 15mm(Disc brake mount for 20mm sold separately) PLEASE CONTACT FOR STOCK AVAILABILITY
