Lock in confident, precise steering with the PRO Tharsis 3Five CNC Stem. CNC machined from AL 7050 alloy and built around an oversized 35mm bar clamp, this 35mm, 0-degree stem keeps your front end stiff and planted so every input transfers directly to the trail.

Highlights

• CNC machined AL 7050 alloy: delivers a rigid, durable steering platform that resists flex under hard efforts.
• Oversized 35mm bar clamp: pairs with 35mm-diameter handlebars for improved front-end stiffness and reduced bar twist.
• Short 35mm length: places weight over the front wheel for quick, agile response on technical terrain.
• 0-degree angle: neutral rise lets you fine-tune cockpit height with headset spacers rather than stem angle.
• 150g claimed weight: keeps the front end nimble without sacrificing strength.

Built for trail and all-mountain

The Tharsis 3Five CNC is engineered to complete the PRO Tharsis 3Five cockpit system. The oversized 35mm clamping interface pairs with 35mm-diameter handlebars to resist twist and flex under the demands of aggressive trail and all-mountain riding, giving you a direct, connected feel when it matters most.

Short length, sharper response

At 35mm — the shortest option in the Tharsis 3Five CNC range — this stem pulls your position forward for fast, reactive steering. The 0-degree rise keeps your bar position neutral and predictable, making it easy to optimise your cockpit ergonomics with spacer adjustments.

Compatibility & Fit

Fits 1-1/8" (28.6mm) steerer tubes and 35mm-diameter handlebars. This is the 35mm length, 0-degree option. The 35mm clamp standard is not compatible with standard 31.8mm bars — confirm your handlebar diameter before fitting.
