THOMSON Aluminum Riser Bar 31.8mm

The Thomson riser bar is 800mm wide with 20mm of rise, 9° of backsweep, and 5° of upsweep. It’s built using 7050 Aluminum alloy for strength and longevity. The long straight section in the middle reduces stress concentrations, especially when using wide Direct Mount stems.

Aluminum MTB 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.

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.

It’s the perfect addition to your X4 Stem or Direct Mount Stem.
