This crank is machined in aluminium and titanium alloys, weights up to 500g, has a flexible configuration for road and mountain and is resistant enough to endure 50.000 cycles (with 1800N of load) according to the ISO 4210:2014. The focus of this project was the study and comparison of different materials, geometries, implicated processes and methodologies with the view of developing a DESIGN crank unit that could maximize RESISTANCE. BestCrank unit was the result. The BestCrank stands out with its high ratio of PERFORMANCE, WEIGHT and EXCLUSIVITY. More...
