These are the Thomson Downhill Alloy 31.8mm Riser Handlebars. Great fit, the classic Thomson look. The most precise steering bar available. 780mm wide, 6 degrees of backsweep and 4 degrees of upsweep. Built using 7050 Aluminium alloy for strength and long life. 65mm wide clamping area to fit Thomson’s Direct Mount stem giving you the most torsional stiffness of any bar/stem combination. Centre section is 99mm wide to move the bending point to the optimal location. 4 separate butting steps ensure the riser bend which is the weak point on any riser bar is as strong as possible. Tapping after forming produces the roundest possible stem clamping area. The Bar is produced by advanced CNC bending to avoid the need for hand grinding. Almost all other bars are manually bent and bends are ground to appear smooth. CNC bending ensures very consistent wall thickness and close tolerances especially in tapered sections. This keeps weight low and fatigue life high. The perfect addition to your Elite X4 Stem or Direct Mount Stem.
