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 seat tube, tighten the knob, and clamp into any Park Tool Repair Stand
The ISC-4 has a hex-shaped shaft that resists twisting while clamped in the stand
Works with a huge range of seat tube sizes with an inside diameter of 24 to 32 mm
