Park's Bench-Mount Repair Stand easily bolts to any workbench and includes Park's shop-quality Micro-Adjust Clamp that handles round and aero seatposts and frames from 7/8-inch to 3-inches in diameter and clamps securely with its quick-release cam and handle that fine-tunes the tension. The clamp also has protective rubber jaws and built-in slots for cables. Plus its jaws are only 2.7 inches tall so they easily fit in narrow areas like on seatposts that aren't raised much. This stand rotates 360 degrees for optimum bike positioning, too.
