I'm looking to upgrade from a used 2011 KHS flite 300 with 2300 group set to a Giant with 105's. Components and looks are important to me. I like the 2013 Defy 1 but noticed compared to the 2014 Defy 1, it has a 12-28 cassette with 23mm tires vs. the 12-30 ansd 25 mm tires on the new 2014. Also the avail 1 has the 12-30 cassette. Im currently riding on a 11-30 which i like. i'm not a strong rider yet but plan to be in the future. Not sure if i should go with a woman's specific bike like the avail 1 or go with the defy 1. i like the colors of the defy much better than the avail's. Looking to make an investment that i can grow into as a rider. I'm an Athena, I'm 5'8 and 215lbs. Any advise would be appreciated.
