1, MTB handlebar diameter: 31.8mm; bar 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.The thickened tube wall increases the strength of the carbon fiber handlebar 2, Downhill handlebar carbon Made of T700 carbon fiber, carbon fiber compared to aluminum alloy: lighter in weight. Much nicer in appearance. Lighter in color. Stronger in compressive strength. Anti-shock. Has the right elasticity and improves the class of your bike in minutes. Carbon fiber bars 1-1/4" are very light, stiff, and the carbon fiber bars vibrate more pleasantly at speed than aluminum alloy bars. 3, Install the mtb downhill handlebar correctly, please follow the specified tightening torque (4Nm); we recommend using a hex wrench to tighten the screw. Since it is made of carbon, we recommend tightening the body to support it by tightening it with your hands. Strong tensions can cause cracks; 4, Carbon handlebar has a torque value of 4Nm and a maximum torque of 5Nm. Just gradually tighten the handlebars alternately. Tighten until the flat handlebars stop moving, then a little more. You can also apply carbon fiber assembly paste to the MTB handlebar to ensure a tight fit with little risk of slipping. 5. bike handlebars Choose the size: The width of the mountain handlebars doesn't really correlate with the size of the wheels, but it depends on your riding style and the type of terrain you usually ride on: make wide bars on a heavy, fast moving bike like an enduro bike makes sense. In general, cross-country riders prefer short handlebars, while enduro riders and downhill riders prefer significantly wider handlebars. 6,The width of the mountain bike handlebars doesn't really depend on the size of the wheels, but depends on your riding style and the type of terrain you typically ride on.
