absoluteBLACK Road Ovaal kettingblad 38T 11-speed Inner 110BCD voor Dura-Ace 9000/Ultegra 6800, zwart (black)
This absoluteBLACK 110 mm oval chainring is designed for the inside of Shimano Dura-Ace 7900 / Ultegra 6700 / 105 or 5700 cranks. It is CNC machined from a single piece of aluminium, creating the perfect combination of light weight and excellent durability for your bike.
The oval shape smoothes the power peaks when turning the crank. As a result, you have a smoother pedal, especially in the mountains, and your muscles tire less. The lower power peaks also reduce stress on the knees.
