ONIPAX Bike Seatpost Clamp 31.8mm 34.9mm CNC Alloy

• [CORRECT INSTALLATION] Install with internal lip facing upward. The ledge sits on top of frame tube to prevent sliding down, ensuring accurate fit and proper clamping force.
• [ELIMINATE SEATPOST SLIP] Precision CNC-machined from 6061 aluminum alloy to provide uniform pressure. Prevents seatpost creeping during mountain trail rides and road cycling.
• [LIGHTWEIGHT STRENGTH] Optimized single-bolt design reduces bulk without sacrificing holding force. Provides reliable stability for daily commuting and gravel riding.
• [ALL-WEATHER DURABILITY] Anodized matte finish resists sweat, rain, and road salt. Guards against corrosion and maintains structural strength in harsh outdoor conditions.
• [FRAME TUBE MEASUREMENT] Fits frames with 31.8mm or 34.9mm outer diameter. Measure frame tube outside diameter, not seatpost size, to select correct clamp dimension.
