PARK TOOL - ISC-4 - INTERNAL SEAT TUBE CLAMP
Clamping directly to freshly painted or ultra thin-walled frame tubing can cause inadvertent damage. The new ISC-4 securely holds most bikes without clamping on any frame tube. To use, simply insert the ISC-4 into the frame’s seat tube, tighten the knob, and clamp into any Park Tool Repair Stand. The ISC-4’s hex-shaped shaft resists twisting while clamped in the stand. Works with a huge range of seat tube sizes—anything with an inside diameter of 24mm to 32mm.
Note: Some seat tubes use an internal sleeve. Do not insert the ISC-4 fully into the frame with sleeves.
