Giant's Defy 1 is a step up from the Defy 2 with the introduction of Shimano's legendary 105 groupset and P-R2 wheelset.
Giant's Defy range sets the standard for endurance road bikes with several accolades for performance, value and comfort. The Giant Defy 1 uses Giant's ALUXX SL aluminium which is super lightweight with a Powercore bottom bracket for a super light and lively frameset coupled to a composite bladed fork with an Overdrive steerer tube for stiffness and sharp steering. The addition of the unique D-Fuse seatpost massively increases compliance at the saddle giving a smoother and more efficient ride. The Defy's acclaimed geometry gives an efficient, comfortable and sporting riding position which suits almost all body shapes.
The Defy 1's componentry is based around Shimano's 105 22 speed groupset which is functionally difficult to beat. Super smooth shifting across the 11 speed cassette, precise front shifting and low weight make Shimano's 105 the benchmark in performance gear systems. The Defy 1 is fitted with an 11-32 cassette to help you on the toughest climbs.
If you are looking for a great road bike for all round riding with a smooth and refined ride then the Defy 1 is a must to consider. Giant offer Defy specific mudguards so you can ride whatever the weather, a unique feature for this category of bike.
