Overfast Aero Alloy Chainring Tavelo-Direct CNC machined centre is stiffAero Fairing 50 34 or 52 36T BCD 110x4 Alu 7075 T651 ~175g (50 34T) While most components from Overfast are made from carbon fibre, these chainrings are made from aluminium. Not just any alloy, but with 7075 T651. The base alloy of 7075 offers exceptionally high tensile and fatigue strength. T651 is heat treated and aged to maximum strength, followed by stress relief via a controlled mechanical pre stretching process, which greatly reduces internal
