Our Downhill bar is 800mm wide with 20mm of rise, 9° of backsweep, & 5° of upsweep. It’s built using 7050 Aluminium alloy for strength & long life. 65mm wide clamping area fits our Direct Mount stem, giving you the most torsional stiffness of any bar/stem combination. 31.8 centre section is absolutely straight over a width of 90mm. The long straight section in the middle reduces stress concentrations, especially when using wide Direct Mount stems. Bars are butted & 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 & contact with the ground. Bars are produced by advanced Hydraulic Press Forming to avoid the need for hand grinding. Almost all other bars are manually bent, & bends are ground to appear smooth. Hydraulic Press Forming ensures very consistent wall thickness & close tolerances, especially in tapered sections. This keeps weight low & fatigue life high. 800mm width. 7050 Aluminium Alloy. Long, straight middle section. Thickened ends from 1.4mm to 1.6mm. Developed by Hydraulic Press Forming. Low weight, high fatigue life. Perfect with Thomson Elite X4 or Direct Mount Stems.
