1, MTB handlebar diameter: 31.8mm; rod -end diameter: 22.2mm; Appearance: UD Matt; flat bar: 760/780/800/820mm; Riser bar: 760/780/800/820mm; flat handlebar back sweep: 9 °; flat handlebar rise: 15mm.riser Handlebar Back Sweep: 9 °; Riser Handlebar Rise: 25mm. Carbon fiber driver 2, Downhill handlebar carbon made from T700 carbon fiber, carbon fiber compared to aluminum alloy: easier in weight. Much nicer in appearance. Heller in the color. Stronger in compression strength. Anti-shock. Has the right elasticity and improves the class of your bike in minutes. Carbon fiber drivers 1-1/4 "are very light, stiff, and the carbon fiber rods vibrate more comfortably at speed than stamina made of aluminum alloy. 3, install the MTB Downhill handlebar correctly, please follow the specified tightening torque (4 Nm); We recommend using a hexagonal key to put on the screw. Since it is made of carbon, we recommend tightening the body to support it by tightening it with your hands. Cracks can arise in strong tensions; 4, carbon steering has a torque value of 4 Nm and a maximum torque of 5 Nm. Just gradually put on the handlebar. Put on until the flat handlebar no longer moves, then a little more. You can also apply carbon fiber mounting paste to the MTB handlebar to ensure a firm seat with a low risk of slipping. 5. Bicycle handlebars choose the size: The width of the mountaineer does not really correlate with the size of the wheels, but it depends on its driving style and the type of terrain where you normally drive: make wide handlebars on a heavy, fast-moving bike like an enduro bike. In general, cross-country drivers prefer short handlebars, while enduro drivers and downhill drivers prefer significantly wider drivers.
