Tiagra 4703 10-Speed 30/39/50t Crankset

Shimano Tiagra FC-4703 Crankset offers a wide triple gear range for riders looking for a low climbing gear and a 10-speed rear cassette. The Tiagra 4703 triple components have a unique cable pull and are all designed to work together and will not work with other Shimano triple or double road series.

Shimano does not include a bottom bracket with the Tiagra FC-4703 cranks and can be found here . Shimano's Hollowtech II crank/bottom bracket system uses a 24mm spindle to provide a stiffer interface and better power transfer when compared to Octalink or square tapered cranks.

• Hollowtech II bottom bracket design
• 45mm chain-line
• 158.8 Q-factor
• Designed for use with Tiagra ST-4703 shifters and FD-4703 front derailleur

The Tiagra 4703 triple cranks have a wide gear range while benefiting from added stiffness that Hollowtech II offers.
