Tiagra FC4500 9spd 52/39 Crankset

Greatly improve the ride quality of your 9-speed set up by upgrading to Shimano Tiagra, arguably one of the nicest 9-speed road cranks currently on the market.  The Tiagra features Shimano's Hollowtech II bearing design, which moves the bottom bracket bearings to the outside of the frame.  This greatly increases strength and stiffness while dually bringing the weight of the bottom bracket bearings down dramatically.

Using new styling, design, and technology, the Shimano Tiagra is an excellent choice for a high end 9-speed set up.

• Available in multiple crank lengths to fine tune your fit
• Aluminum construction adds stiffness while reducing weight
