Giant Defy for '19 will fit 32mm tires. I went to buy a '19 Defy 2 at my lbs but came home with a '18 Defy. Only fits a 28mm but $600 discount I couldn't pass on. The fitted 25mm tubeless tire ride very well on the dirt/gravel roads around my house. Better than the 32mm tires that came on my Trek FX3. The Defy has disk brakes but is considered an 'Endurance' style bike.
