SRAM Force 2x Chainring Kit - 50/37t 2x12-Speed 8-Bolt Direct Mount Black D2. 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.
