The A.R.T. suspension allows for a twenty percent increase in chain growth over traditional suspension systems. This means that pedaling is made more efficient, which allows you to take on a variety of terrain. Another way in which the Range 2 (2011) is a step up from the Range 3 (2011) model is its Syntace X-12 142mm rear dropout axle system, which provides improved axial/radial clamping, as well as easy adjustment. This model lacks the Range 1 (2011) model's Fox fork and rear shock (having a Rockshox fork and rear shock instead), Shimano XT drivetrain components (having SRAM components instead), and Race Face carbon handlebar (having an in-house aluminum handlebar instead).
