The 1981 Redline Pro-Line Frame/Fork is designed to allow more pedaling room for the taller rider (5'6" and up). Both frame and fork are all chrome-moly. The fork is fully heat-treated after welding for maximum durability. The 5 inch head tube is also unique. This provides exceptional rigidity in the head area to maintain Red Line's race-proven geometry. Frame: 4 pounds 4 ounces; Fork: 1 pound 12 ounces. Colors: Red, white, and chrome.
