The Thomson Elite DH 31.8mm Riser Handlebar is 800mm wide with 20mm of rise, 9° of backsweep, and 5° of upsweep. It’s built using 7050 Aluminium alloy for strength and long life. 65mm wide clamping area fits Thomson's Direct Mount stem, giving you excellent torsional stiffness. The long straight section in the middle reduces stress concentrations, especially when using wide Direct Mount stems.These handlebars are butted and tapered in many steps for optimal fatigue life. Ends of the bar are thickened from 1.4 to 1.6mm to resist damage from impacts and contact with the ground.These Thomson bars are produced by advanced Hydraulic Press Forming to avoid the need for hand grinding. Almost all other bars are manually bent, and bends are ground to appear smooth. Hydraulic Press Forming ensures very consistent wall thickness and close tolerances, especially in tapered sections. This keeps weight low and fatigue life high.Together with a Thomson stem, this is one of the best Aluminium cockpits you can get. It’s the perfect addition to your Thomson Elite X4 Stem or Thomson Direct Mount Stem.Thomson Elite DH 31.8mm Riser Handlebar SpecificationsWidth: DH - 800mm.Rise: 20mm9° of backsweep5° of upsweep.Material: 7050 Aluminium alloy.Very durable and extremely strong.Thickened ends from 1.4 to 1.6mm.Developed by Hydraulic Press Forming.Perfect addition to Thomsons Elite X4 stem or Direct Mount stem.
