MICRO-ADJUST CLAMP FOR PCS-4, PRS-5, PRS-6, PRS-7 REPAIR STANDS PARK TOOL 100-5D

The Park Tool 100-5D is the micro-adjust repair stand clamp designed for the Park Tool PCS-4, PRS-5, PRS-6 and PRS-7 repair stands and for the more recent versions of the PCS-1. It is the most direct way to bring a stand from these series back to full efficiency, with a repair stand clamp that holds round and aero tubes from 23 to 76 mm.

Many Park Tool repair stands work for years, and the first part to wear out is the clamp. The 100-5D uses the cam-actuated micro-adjust clamping system: you set the jaw opening to the tube size, close the lever and the clamping comes in progressively, without jolts. Continuous adjustment lets you find the right pressure for every frame, including the thinnest carbon tubes, which are not crushed. Opening the lever releases the bike in an instant. A new clamp also means intact jaw covers and a mechanism that works smoothly again, essential conditions for working on painted or carbon frames without leaving marks.

Construction follows Park Tool standards for shop use: powder-coated, precision-machined die-cast aluminum main body, narrow 70 mm tall jaws and jaw covers replaceable with part 1960. The slim jaws slip into tight spaces and grip even the shortest seat posts, common on modern bikes with compact frames.

How to check the compatibility of the Park Tool 100-5D clamp

• PCS-4, including PCS-4-1 and PCS-4-2
• PRS-5, PRS-6 and PRS-7 made after June 1996, with composite top tube
• PCS-1 made after 2002: check for the embossed "939" under the lever
• For PRS-5 stands made before June 1996, the correct clamp is the Park Tool 100-3D

Why choose the Park Tool 100-5D

• Original replacement to extend the life of Park Tool stands already in use
• Cam-actuated micro-adjust: progressive clamping and instant release
• Clamping range from 23 to 76 mm on round tubes and aero profiles
• Narrow 70 mm jaws, also suited to short seat posts
• Powder-coated die-cast aluminum body and replaceable jaw covers (1960)

Before installing, check the model and production year of your stand: once fitted, the Park Tool 100-5D micro-adjust clamp gives the stand back a precise, fast grip that respects the frame.
