Samox R5 crankset series design creates the perfect blend of elite performance and professional durability via engineering solutions and innovative design. The R5 chainring is a CNC-milled aluminum unibody of two chairings to not only reduce the overall weight significantly, but also improve its overall structural integrity and durability. Symmetrical and asymmetrical designs communicate light weight and speed, also allow for the use of even less material in construction for better structural integrity. A hollow forged aluminum arm with variable thickness sections endures the material stresses and reduces the weight.
