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.

I have now changed two inner and outer chainrings on two cycles. I bought them all from you. They we the cheapest offered that I could find on the internet. Delivery was swift and staff helpful. The change has been well worth it. The winter ring is not as pretty but is more practical. Thank you.
