New or Upgrade Bike
I currently own a Giant Defy 2 2012 which does not have that many miles on the wheels as I was more focused on running the last few years, including a few marathons last year, mainly to loose weight
I am doing a few 70.3 this year (Outlaw and Dublin) and have been thinking about a new bike, I was looking at a Felt AR5.
However I wondered if it would be worth upgrading a few things on the Defy instead and if that was the best option what should I do first?
Lastly being a 200lb+ guy who needs to loose at least 14 pounds, I often wonder if a new bike or upgrades will make that much difference!!!
Thanks for any comments/suggestions
