Titanium Seatpost Shim - 27.2 to 30.9mm

The Carver Bikes Titanium Seatpost Shim adapts a 27.2mm seatpost to fit a 30.9mm seat tube, giving riders a clean, secure way to run their preferred post size without compromising fit. Its brushed titanium finish and corrosion-resistant material help reduce the risk of the shim bonding to the frame over time—an advantage for bikes that see wet weather, sweat, or long service intervals, especially with aluminum frames.

• 27.2mm to 30.9mm sizing - Allows accurate fitment of a 27.2 seatpost in a 30.9 seat tube for reliable positioning and easy setup
• Titanium construction - Corrosion resistant to support long-term serviceability and frequent adjustments
