Description:

• Lightweight hollowtech ii 105 11-speed chainset.
• 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 hg-x 11-speed chains for increased contact to provide greater efficiency and improved power transfer.
• Hollowtech ii allows the bottom bracket bearings to be spaced wider apart, enabling the use of larger bearings and an increased axle diameter.
• Can be used with shimano external or press-fit bottom brackets.
• The system allows for easier installation, adjustment, and maintenance.
• Lightweight anodised sg-x aluminium chainrings for smooth and precise shifting.
• Includes left & right crank arms
