Shimano Tiagra FC-4703 Crankset

Tiagra FC-4703 Crankset by Shimano - Riding fun with smooth shifting

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

Technology:

2-Piece Crankset
With the 2-piece designed cranks from Shimano, the right crank arm is precisely matched to the interaction with the bottom bracket. This increases the stiffness and keeps the weight low. Further spaced bearings also improve strength and contribute to more pedalling efficiency. The precision manufacturing of the bearings ensures easy installation and low maintenance. 2-Piece cranks share a 24mm axle diameter with Hollowtech II cranks, so they are also compatible with Hollowtech II bottom brackets.
