Overview
Our Winter line of Shimano 110/4 bcd oval chainrings is designed for new type of Shimano cranks like Dura-Ace 9000, Ultegra 6800, 105- 5800 and others. This is a simplified version of our Premium line. Same aluminium, teeth and shifting ramps, but less material machined out on the outer side for easy maintenance and cleaning on winter training bikes. Weight is increased on these chainrings as compared to our Premium line for that reason.
