Signature to the Allex serious is that they are composed from advanced materials that allow bikers to ride faster and with more power than usual. This makes them especially friendly for racing and other competitive bike sports. The group is broken down into six separate groups: Pro, Expert, Comp, Elite, Standard, and Junior. Each of these is then broken down into Double and Triple. The double units utilize a double crankset, whereas the triple units utilize a triple crankset.
