8 Bolt Spider Shimano Dura Ace Chainrings

Our DA spider integrates Shimano Dura Ace 12 speed rings with our RGXC 8bolt crank interface. If you want to run Shimano 11 speed DA, you're going to need to use a FC-R9200 12 speed small ring, otherwise you'll run into compatibility issues.

Spider weight: 73 grams
