This is a very lightly used 2010 Cannondale Synapse Carbon endurance bike with Shimano Ultegra components. It has been modified from the stock setup by putting a wider range cassette and derailleur on the back (11-34 for a 1-1 low gear), a different saddle and more durable tires. Otherwise a stock bike that has been professionally maintained and only ridden on short fitness rides. Please let me know if you have any questions or would like make a reasonable offer.
