Absolute Black Chain Ring - Road Oval Winter 110 BCD x 5 (not SRAM)

Our Winter line of Shimano 110/5 bcd oval chainrings are designed for pre-2014 cranks like Shimano Dura-Ace FC7900, Ultegra FC6750, Shimano 105 -5750 and many more with 5 bolt fitting. 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. Ideal for your training bike.

Winter line chainrings are a simplified version of our state-of-the-art Premium line. They use same aluminium, teeth and shifting ramp design. However they are less machined out from the front for easy maintenance and cleaning when used on winter bikes. This chainring is designed for your winter/training bike where weight is not an issue, but easiness of cleaning is.
