The FSA Gossamer MegaExo Crankset is a straightforward crankset that will provide you with easy installation and a smooth transition without providing any thing too flash.
Rather than having hollow or carbon crank arms they are made from cold forged aluminium and while it makes them strong and stiff, it also adds to the weight. The aluminium means they have more flex than what you will experience with a higher end crank. The FSA Gossamer MegaExo crank has a monocoque design in the spider and crankarms, with AL7075 100% CNC machined chainrings.
