In 1978 the ProLine was modified with a stronger rear dropout,
lighter forks, 5" headtube, and geometry change for better
handling. The frame was only offered in white in '78.
Redline began to expand their product offerings with the famous
V bars and redefined Redline Proline double clamp stem
thoroughly tested by Byron Friday. The stem features a 45
degree angle brace allowing for more surface area to be welded
for strength. The clamps in '77 were the same as the '75
prototype stem but Redline modified to increase the size for
more gripping power, strength, and stamped for Redline quality.
The bike features era correct parts and the Webco Magnesium
wheels are original with the introduction of Carlisle Aggressor
MX front tire.
Hope you all enjoy another historical Redline ride.
