Built to withstand the rigors of every day shop use, the PRS-2.3 is the stand of choice for professional mechanics around the world. The dual-sided top tube allows two mechanics to work simultaneously, and rotates 360 degrees allowing a single mechanic to work on multiple bikes more efficiently. Stand height and clamp position are firmly secured in place using our proven lock block system. Built from heavy-gauge oversized steel tubing, then chrome plated and powder coated for years of carefree use. The PRS-2.3-2 features the 100-3D Micro-Adjust Clamp, with a cam-actuated adjustment system for quick entry, adjustment and exit. The 100-3D features narrow clamping jaws to fit into tight areas or on short seat posts, and clamps nearly any tube from 23 to 76 mm (7/8" to 3"), including aero tubes and dropper posts.
