The SRAM Force 2x chainring kit is lightweight stiff and durable. The one piece construction ensures that none of your effort goes to waste. A 13 tooth delta on all chainring pairs ensures precise shifting for any setup as well as a less dramatic change in cadence during front shifts. And the technology that has been packed in makes it SRAMs longest lasting chainring set yet.
