Park Tool Clamp Part PRS-23&4 #100-3C

Our tried-and-true adjustable linkage clamp design has been a constant companion for professional mechanics around the world for over 50 years, and it still securely holds most traditional seatposts and frames. A great option for assemblers and mechanics who work on older bikes, with dead-simple single-lever operation and cable reliefs on both jaws. The 100-3C features solid cast-aluminum construction and durable replaceable clamp covers.
