Full Speed Ahead Omega Adventure crankset with 50/34 tooth chainrings, 175mm crankarms, 19mm spindle. Came on a new bike, used for maybe 100 miles and swapped for the same model crankset with shorter arms. Chainrings should have tons of life left. Some light scratches on the drive side crankarm. Feel free to reach out with any questions. I ship on the next business day. No returns accepted.
