Shimano 105 5700 10 Speed Chainset
The benchmark for quality and performance. The chainset is "one of the stiffest we’ve ever ridden," says Bike Radar of the component. Unlike Dura-Ace and Ultegra, the inner chainring of the triple option mounts directly on the crank arm, rather than on the middle ring. The chainrings themselves are hard wearing and are inexpensive to replace.
The innovative HollowTech forged and anodized aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low. The chainring teeth have been developed to work in conjunction with the CN-5701 chains for increased contact to provide greater efficiency and improved power transfer, and lightweight anodised SG-X aluminium chainrings allow for smooth and precise shifting.
