Our Silver 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, making them ideal for your training bike.

Size: (Mass +/-1g): 34T (39g), 36T (43g), 50T (150g), 52T (160g)
