The Shimano 105 5700 10 speed chainset comes in black or silver alloy options and is constructed using Shimano's lightweight HollowTech II technology.Innovative HollowTech forged and anodised 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.

HollowTech II allows the bottom bracket bearings to be spaced wider apart (outboard from the frame), enabling the use of larger bearings and an increased axle diameter. The system also allows for easier installation, adjustment, and maintenance.

The lightweight anodised SG-X aluminium chainrings help for a smooth and precise shifting
