Boardman state that the alloy frame and carbon fork maintain the same geometry as the ADV 8.9 for stable and predictable handling off-road, but with quick release wheels. All but mirroring the gearing ratios of the ADV 8.9, the team behind the ADV 8.6 have opted for Shimano Sora drive train and FSA Velo Pro chainset, as well as mechanical Tektro disc brake to help keep the price point down. You’ll want to understand this bike’s essential features before purchasing it, including its complex shifting system and how it is different from similar bikes. The Genesis has a 21 Speed drivetrain which is great for smooth changing of gears as you ride on bumpy roads, uphill trails and other types of terrains. The Shimano EF40 gears are lightweight and allow you to shift several gears in one shift. For example,  typically gear shifters are placed on the handlebars of a bike and allow you to change both the front and rear gears. Lower gears offer a smoother way to climb hills while higher gears increase speed exponentially. If not for extreme sports, a good suspension that allows people to enjoy the comfort of body exercise. The basic configuration of Genesis Mountain bike gs29, which is relatively rare in low-priced mountain bikes, is the shock fork and shock absorber. The lighter mass of the mountain bike allows more challenging maneuvers for roads with steps. The aluminum four-link suspension mechanism frame is also very good, with a shock absorption effect.
