You'll always find the perfect gear with Shimano's Tiagra Crankset. It's crafted from aluminum for low weight and efficient power transfer, while the integrated axle furthers both of those attributes. It shifts positively as well with ramped and pinned SG-X chainrings that boost shifting speed and precision.
