In-Depth Description

Flawless integration proven in the wind tunnel: Genuine Bianchi Reparto Corse replacement parts for your Oltre.

The Bianchi Oltre platform has completely redefined the concepts of aerodynamics applied to competitive racing, where every single line is sculpted to cheat the wind and manipulate airflow to the rider's advantage. In such an extreme structure, even the seatpost clamp must remain completely invisible. Whether you are building up a new dream frameset from scratch, replacing a worn-out component, or refreshing a tensioning bolt damaged by improper torque, this genuine original internal expander returns your bike to exact factory specifications.

Engineered for High-Modulus Carbon Fiber Layouts

Modern aero racing frames require highly precise, evenly distributed clamping pressure. Excessive localized pressure risks damaging the carbon tubes, while an inadequate clamp load causes the seatpost to slide under high-wattage efforts. This wedge expander mechanism is precision-machined to the exact tolerances specified by Bianchi’s R&D engineers. It applies pressure uniformly against the internal walls of the proprietary profiled seatpost, making it safe and structurally ideal for the premium carbon fiber used across the Oltre RC, Pro, and Comp lineups.

Hidden Aero Design & Unyielding Hold

By tucking the clamping mechanism completely inside the frame junction, the clamp eliminates surface air turbulence, giving the bike clean, minimalist, and aggressive lines. The contact surfaces of the expander blocks are optimized to maximize mechanical friction. When paired with high-quality carbon assembly gel, this system prevents micro-dropping of your saddle height even over the roughest tarmac or during violent out-of-the-saddle sprints.

CicloBottega Workshop Tech Tip

Expert Advice: The internal wedge locking mechanisms on modern hyperbikes are micro-sized yet vital structural components. If you have experienced seatpost slippage or accidentally over-tightened the hardware and damaged the original threads, replacing the entire wedge unit with this € 45.00 genuine spare part is the absolute safest way to ride securely and protect your premium carbon frame.

Pro-tip for a flawless installation: Before inserting the new clamp assembly, thoroughly clean the inside of the frame's seat tube cavity and the seatpost surface to remove any old debris or residual grit. Apply a thin, even layer of premium carbon assembly paste (carbon gripper paste) exclusively to the contact areas between the seatpost and the frame structure. Crucial rule: Do not get carbon paste onto the tension bolt's internal threads; instead, add a minute drop of mechanical grease to the bolt threads to ensure an accurate torque wrench reading. Always use a calibrated torque wrench and strictly follow the maximum torque rating (Nm) specified by Bianchi.
