PRO Introduces New 2021 Mountain Bike Components


September 3, 2020 – PRO expands its range of premium mountain bike components with four new carbon handlebar offerings and two new dropper posts designed to fit a broader range of riding styles. Employing the latest technology from its flagship Tharsis component range, PRO’s lineup of Tharsis 3Five carbon handlebars expands for 2021 with additional rise options to suit cross country riders to enduro racers and everyone in between. PRO also builds out its dropper post selection with the lightweight Tharsis dropper with 2-bolt head design and oval post shape as well as adding a new 34.9mm Koryak Dropper Post to fit even more frame types.

Tharsis 100mm Dropper Post

For rowdy gravel adventures or high-powered cross country races, the new 100mm Tharsis Dropper Post delivers all of PRO’s proven performance at a minimal weight. Featuring a new, 2-bolt head design with titanium bolts, full alloy internals, and oval shape, the new dropper tips the scales at just 415 grams. The post’s unique oval shaft also works to reduce side play for a more stable, responsive ride when throwing down the power. Available in three post diameters (27.2, 30.9, 31.6mm), the new Tharsis Dropper is ready for any adventure, whether you’re hitting the gravel or shredding some singletrack.

Tharsis 3Five Carbon Handlebar Lineup

Building on the early success of the Tharsis 3Five component range, PRO adds four new handlebar options, offering more choices to fit a wide range of rider needs. Joining the popular Tharsis 3Five Rise bar that launched last year are the four new models, including the Flat, Flat Top, Minirise, and High Rise. Each of the new Tharsis Carbon 3Five handlebars varies in rise and upsweep, delivering a selection of handlebars to accommodate every rider and riding style. All 3Five bars feature a 35mm diameter for added stiffness and steering control without sacrificing overall comfort.
