Founded in 1972, Giant is the largest bicycle manufacturer in the world.
Giant is the world's leading brand of high quality bicycles and cycling equipment. As part of the Giant Group, founded in 1972, the Giant brand combines craftsmanship, advanced technology and innovative design.
Giant has long been one of the leading innovators in cycling. They introduced lighter and stronger aluminium frames at a time when steel was the industry standard. They were the first to make carbon fibre bikes widely available to the world. They defined modern road bike design with Compact Road geometry. And the patented Maestro suspension revolutionized the full-suspension bike segment.

| Weight | Unfortunately, there is no standard for weighing bikes that all manufacturers adhere to, and the weights listed are often inaccurate. To find out the exact weight of a bike in a given size, you need to have the bike weighed at the store, as well as a model from a competing brand – this is the only way to get accurate figures for weight comparison. |
