Shimano 105 Triple 5703 lightweight HollowTech II 10-speed chainset forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low.
The chainring teeth 50/39/30 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 allows for easier installation, adjustment, and maintenance.
It also has lightweight anodised SG-X aluminium chainrings for smooth and precise shifting and works with with ST-5700, ST-6700 or ST-7900 shifters.
Please note the chainset is supplied with a bottom bracket axle but the price does not include the bottom bracket cups which need to be ordered separately from our bottom bracket section.
