Shimano Ultegra crank 2-FC-6800
Easy and reliable Ultegra crank with a large selection translation
The new Ultegra crankset is characterized by a very high switching performance. The gearshifts are doing with high precision. Here optimum power transmission is achieved by the new tooth profile, in addition is this new tooth profile in conjunction with the new Ultegra derailleurs maximum security against the jump off the chain.
The reduced weight compared to its predecessor was achieved through the broad HOLLOWTECH II-arm design and a reinforced outer chainring. In terms of stiffness and lightness, the new Ultegra cranks highest standards to meet.
The appearance comes naturally not too short, the proven DURA-ACE 4-arm design has been maintained and has less weight, with higher stiffness.
