What Our Gearhead(R) Experts Are Saying:"I spec the PRO Tharsis ThreeFive Alloy Riser Handlebar on trail and all-mountain builds where the rider wants the control benefits of an oversized 35mm clamp diameter without committing to a carbon bar. The variable wall thickness tuning gives it a compliance characteristic that takes the edge off rough terrain without feeling vague, and at 250 grams the weight is impressively low for an alloy bar at this spec level."The oversized 35mm clamp diameter is not a marketing detail, it is a measurable stiffness advantage that translates directly into more precise steering response and better front-end control on technical terrain. The PRO Tharsis ThreeFive Alloy Riser Handlebar brings that advantage to an AL-7050 alloy construction that prioritizes durability and control for riders who want the performance of the carbon Tharsis platform in a package built to take a beating. Variable alloy tube wall thickness tunes the bar for compliance across its length, smoothing out trail vibration without sacrificing the torsional stiffness that confident descending demands. A 20mm rise with 9-degree backsweep and 4-degree upsweep positions the rider naturally for all-mountain and trail geometry bikes, and cutting marks at clearly indicated intervals bring the 800mm starting width down to 720mm for riders who prefer a tighter cockpit setup. At 250 grams it carries the width and spec of a performance bar without the weight penalty you might expect from an alloy construction at this diameter.
