FSA SLK Carbon Crankset External type Bottom bracket (included) 175mm 53/39 chain rings It's a great carbon crankset with external type bottom bracket and makes for a great upgrade if you currently run octal link, square taper, or some other old school type bottom bracket. Those cranks cost $399 last year and still cost $275 + tax today. $145 OBO shipped within the CONUS. If interested, please email me directly at [email protected].
