Selling my lightly used Giant Defy with a Shimano 105 drivetrain. The bike has been maintained well over it's lifespan and didn't get to see very many rides unfortunately. I have upgraded the wheels to the P1800 DT Swiss and it rides like an absolute dream. I'm looking to sell in order to get a gravel bike. Can sell with original wheels (no cassette or tires) at a lower price and sell the p1800 separately also.
