Description

The single pinch, full wrap 401 Series Flight crank is back, referenced from the original drawings and built to original era specifications. The arms are swaged 4130 chromoly with decal pockets stamped into both sides and the single pinch bolt installation system the Flight crank was known for in the 1980s.

The matching Redline Flight 44 tooth sprocket is CNC engraved to recreate the original logos and surface design. The spindle borehole diameter goes back to the original 1980s dimension and pairs with the double dimple Redline spindle. Arms come in 175 mm or 180 mm and the set is delivered in custom Redline vintage packaging.
