Details of the frame:
The Sheriff stepped it up a notch by using one of the best frame materials available: 100% seamless 4130 Japanese Chromoly with seat stay mounted brake mounts. Other key features include an integrated head tube, mid size BB shell and externally machined headtube. The lightweight Chromoly 5mm thick dropouts are even heat-treated after laser-cutting for unsurpassed strength. NEW for 2008 the frame now has removable chain tensioners, removable Gyro tabs and a built in seat clamp. Sizes come in a 20.5 and 21" top tube length in Galaxy and Ocean colors chosen by Scotty himself. Weighs just only 4 lbs. 11oz for 20.5" version
