The PRO Tharsis 3Five 20 Alloy Handlebar is engineered for Enduro racing and aggressive trail riding. Built from high-grade AL7050 aluminum and featuring a 780-millimetre width, it delivers an ideal balance of stiffness and compliance. The advanced alloy construction, paired with an oversized 35-millimetre clamping diameter, optimizes vertical compliance to help reduce rider fatigue. This performance is fully retained at the full 780-millimetre width—now widely regarded as the most popular handlebar size—eliminating the need for trimming.
An 8-degree backsweep promotes a neutral, comfortable hand position for improved control, while bar roll adjustment allows riders to fine-tune their cockpit setup. Further customization can be achieved via PRO Tharsis 3Five Stem options. Durable yet lightweight, the Tharsis 3Five 20 Alloy weighs just 285 grams. This 20-millimetre rise model sits within a broader range that also includes 10-, 30-, and 40-millimetre rise options.
