PRO Tharsis Stem

This stem is designed exclusively for handlebars with a 35mm clamp diameter. It will not fit standard 31.8mm bars, so please verify your handlebar size before purchasing.

The larger 35mm interface increases the surface area at the connection point, which significantly improves front-end stiffness. This results in more precise steering and better feedback when navigating technical, high-speed terrain.

A zero-degree rise keeps your cockpit height neutral, which is ideal for enduro and all-mountain riding where you want to maintain a balanced, aggressive posture. It prevents the front end from feeling too high, helping you keep weight over the front wheel for better traction.

While it is built for the rigors of enduro and all-mountain riding, it is certainly capable of cross-country use. However, keep in mind that it is engineered for maximum stiffness and durability rather than weight savings, so it may be heavier than dedicated lightweight XC stems.

The 4mm stack height is quite low, which offers a sleek, minimalist look. You may need to adjust your headset spacers to ensure your steerer tube length is compatible, as you might find yourself needing an extra spacer compared to a stem with a taller stack height.

Because it is CNC-machined from high-grade 7050 alloy, this stem is very durable and requires minimal maintenance. Simply check the 4-bolt faceplate torque specs periodically to ensure they remain secure after heavy riding sessions.
