Redline 401 Single Pinch Flight Cranks with Techmatik BB
Using original drawings and specifications unearthed in the Kastan archives, the Redline by Kastan 401 Flight cranks set is made from the original Flight Crank 2D drawings (dated 1982). The crank arms are produced from Chromoly and swaged prior to press forming through three separate moulds to achieve the iconic, tapered Redline Flight crank shape.
The Redline X Flight sprocket is offered only in 44 tooth at the present time. The diameter of the bore hole reverts to that of the original to accept the Double Dimple Redline driver Spindle.
The set is delivered in custom Redline by Kastan packaging.
The Techmatic BB Bearing and cup set is included as the ultimate finishing touch to these cranks.
Only a limited number of cranksets will be available to pre-order on this first production run.
