JKY 41mm Folding Bicycle Quick Release Seat Post Clamp This aluminum seatpost clamp is designed for compatible folding-bike frames using an approximately 33.9 mm seat post. The 41 mm quick-release collar combines an extended lever, textured grip, 2 mm hex set screw and anodized finish at approximately 63 g. Measure Before Ordering A seatpost collar clamps around the outside of the frame seat tube and cannot be selected from seatpost diameter alone. This 41mm clamp for a 33.9mm seatpost must also match the seat tube outer diameter and mounting area. Compare the original collar before choosing this folding bike seatpost clamp replacement. Extended Quick-Release Lever The extended lever quick release seatpost clamp provides added leverage for easier opening and closing. Its textured anti-slip grip supports convenient seatpost removal and quick saddle-height adjustment without excessive hand force. Set Screw for Stable Positioning This seatpost clamp with set screw uses a 2 mm hex adjustment point for additional positioning. Correct adjustment helps reduce unwanted loosening, slipping and seatpost movement during normal riding, but cannot replace correct clamp sizing. Anodized Aluminum Construction The anodized aluminum folding bike seatpost clamp balances structural support with an approximate weight of 63 g. The alloy body helps resist everyday wear, oxidation and corrosion, while supporting lasting color. Choose Black, Red, Silver, Gold or Purple. Replacement and Installation Use as a replacement seat collar for a compatible folding bike only after confirming the 41 mm clamp specification and approximately 33.9 mm seatpost reference. Position the clamp on the correct frame area, adjust the quick-release tension and tighten the set screw appropriately. Do not overtighten. After installation, confirm that the saddle remains stable and the lever does not contact the folding mechanism, cables or other bicycle parts.
