A bench-mounted micro-adjust clamp support with 360-degree rotation; the bench and mounting fasteners are part of the installation decision.
Bench-mounted support; suitable surface and fasteners required
Compare the clamp-to-mount reach and bench-to-clamp height with the bicycle and the area you need to reach. Do not assume that the bench edge, drawers or nearby wall will leave the required clearance.
What this choice changes
The PCS-12.2 is a way to add a bicycle clamp to a permanent workbench without setting a repair stand on the floor. Its mounting surface carries the installation, so choose it after checking the bench and fasteners rather than simply finding an unused corner. The mounting bolts are not included in the listing’s full description.
The cam-operated clamp offers fine adjustment and 360-degree rotation. Its narrow jaws measure approximately 7 cm along the tube, which matters when the permitted clamping area is short. Check the approved support point, available jaw space and clearance around the bench; a tube fitting between the jaws is only one part of a suitable mounting arrangement.
The steel structure uses glass-filled nylon fittings and internals. Approximately 30 cm from the mount centre to the clamp centre and 25 cm from the bench to the clamp axis help you plan bicycle clearance and working access. Choose the folding PCS-10.3 if the work location needs to move or the bench cannot support a permanent mount.

Compare the clamp-to-mount reach and bench-to-clamp height with the bicycle and the area you need to reach. Do not assume that the bench edge, drawers or nearby wall will leave the required clearance.
The stand does not establish the strength of an existing bench. Confirm the surface and fastener requirements for the complete installation before treating the stated load limit as usable in your workspace.
From the model’s instructions
The exact stand manual directs cleaning the bicycle tube and jaw covers before clamping.
The manual distinguishes occasional grease on clamp threads and a small drop of oil at pivots from dry areas: do not lubricate the compression cone, composite cup or inside the top-tube assembly.
The full product description says they are not. Select an appropriate mounting arrangement for the actual bench and follow the stand and fastener requirements; a generic bench is not a verified installation.
Choose the bench-mount format when you want a permanent clamp location and have a suitable bench. The PCS-10.3 instead brings its own folding floor base. The important comparison is the work location and installation, not just the similar clamp operation.
Check the component maker’s permitted contact point and clamping instructions. Jaw clearance does not establish permission to clamp every frame or post, and the lower diameter limit differs between the selected listing and current maker page.
