The Boss product range has been developed for riders who want an upper-level mountain bike. The Boss is for those consumers who are focused on a high-quality frame, ride quality and component package.

Over the last year, the popularity and success of the Boss range have been overwhelming. Consumers come in to look at Giant, and after some direct comparison often end up purchasing a Boss. Why? Because these bikes deliver on two fundamental purchase requirements - value and ride quality.

The Boss 4.0 distinguishes itself from its nearest competitor (the Talon 27.5 3) in the engineering and quality of its frame. It also delivers some high-end finishes that are rarely if ever seen at this price, such as:

/ The frame uses XDS's lightest aluminium frame called X6 ULTRALIGHT; it's 10% lighter than many competitors frames and 35% stronger.

/ Internal gear and brake cable routing are used to create a super-clean finish. Cables are also less susceptible to dirt, mud dust and grit everything that adversely influences gear shifting quality.

/ Tapered head (1.5 inches at the bottom and 1.125 inches top), creates a stronger junction at the front of the bike. Welds surface areas are increased and down tube profile is made larger. This increases the torsional stiffness of the frame, ensuring every effort is rewarded with forward motion.

/ Smooth welds are very labour intensive. So it's a testament to how much effort XDS put into creating the Boss 4.0. The throat of the weld is also wider to create a stronger connection between the chassis tubes.

/ Slim seat stays help induce vertical flex in the Boss 4.0 frame. This means more comfort for the rider.

Shimano Alivio components are used in the Boss 4.0 package. These components sit at the upper end of Shimano's recreational range. It's perfect for the rider, who wants a good quality first-time mountain bike to see if they will enjoy mountain biking. Designed to tackle easier mountain bike trails through to Blue-Square intermediate level trails such as those at Lysterfield Mountain Bike Park.

Drivetrain components use a total of 27-gears and result in smooth gear changes under load for the beginner rider. SR Suntour suspension fork has 100mm of suspension travel and comes with a LOCKOUT lever to turn the suspension off when it's not needed, such as on smooth bike paths and smooth climbs. Shimano Alivio hydraulic disc brakes provide smooth and reliable performance in dusty, gritty or muddy conditions.

The frame comes with a Lifetime Warranty, Shimano parts have 2 years, everything else 1 year, and Ivanhoe Cycles offer 2 Free Services which are valid for 12 months.
