Aero 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 stresses, minimising warping and distortion for precise machining.
Featuring an aluminium fairing for extra marginal aero gains, or just bonus points for looks on your bike.
Certain sections of the chainring were hollowed out to optimise weight without compromising on stiffness.
