"...I am only asking $335 for it so I am surprised I haven't gotten one call. I paid $375 for it and its only a couple months old with less than 100 miles on it..."
If you paid 375 then presumably someone else can pay that as well, for a new bike. To buy a used bike, no matter how pristine, a buyer will likely insist on getting a steeper discount. If you're set on getting a road bike, you probably have to take a bigger loss on the sale of your current bike. Consider it just part of the cost of getting the bike you want.........or maybe just keep 2 bikes.
