Titanium Seatpost Shim - 27.2 to 31.6mm

The Carver Bikes Titanium Seatpost Shim converts a 27.2mm seatpost to fit a 31.6mm seat tube, providing a clean, secure interface when a frame’s seat tube is larger than the post you want to run. Built from titanium with a brushed finish, it’s a smart choice for long-term serviceability—especially on bikes that see wet conditions or frequent seat height adjustments.

• 27.2 to 31.6mm Fit - Allows precise use of a 27.2mm seatpost in frames designed for 31.6mm posts
• Titanium Construction - Corrosion resistant and helps reduce the risk of galvanic seizing, particularly in aluminum frames
• Brushed Titanium Finish - Durable surface that holds up well to repeated installs and adjustments
