MICRO-ADJUST CLAMP FOR PCS-10, PCS-11, PCS-12 REPAIR STANDS PARK TOOL 100-25D

The Park Tool 100-25D is the micro-adjust repair stand clamp fitted to the Park Tool PCS-10, PCS-11 and PCS-12 repair stands and to the PRS-25 race stand. It is the original replacement when your stand's clamp is worn, and a real upgrade for anyone who wants to hold the bike precisely on round and aero tubes from 23 to 76 mm.

Clamping is handled by the Park Tool cam-actuated micro-adjust system: first you set the jaw opening to the tube size, then you close the cam lever, which completes the clamping with progressive, controlled force. Adjustment is infinite, with no fixed positions, so you can dose the pressure even on carbon tubes and reduce the risk of crushing them. Opening the lever releases the bike immediately: a real advantage when the bike goes on and off the stand several times in the same work session.

The main body is powder-coated, precision-machined die-cast aluminum, built for everyday shop use. The jaws are narrow and 70 mm tall: they fit where space is tight and grip short seat posts on modern frames securely. The jaw covers are replaceable with Park Tool part 1960, so the clamp keeps a clean and secure grip over time.

Why choose the Park Tool 100-25D

A shop tip: whenever possible, clamp the bike by the seat post rather than the frame tubes, and set the opening so the lever closes with a firm push but without forcing it. To bring your Park Tool stand back to day-one precision, the Park Tool 100-25D micro-adjust clamp is the original choice.
