Tiagra FC-4703 crankset by Shimano - riding fun with fluid shifts
The Shimano Tiagra FC-4703 is a 10-speed crankset with three chainrings for use on Road bikes or City bikes. It has an asymmetrical 4-arm spider (110/74 mm bolt circle), as used for the first time on the 11-speed cranks of the Dura Ace, Ultegra and 105 series. This results in great advantages in terms of the ratio of stiffness to weight. The integration of crankarm and bottom bracket (2-piece design) also contributes to stability. Last but not least, the FC-4703 aluminium crank convinces with stable, smooth and frictionless gear changes, which clearly means more riding pleasure.
