34.9 mm Dropper Post Shaft Clamp Tool

Engineered for modern 34.9 mm oversize droppers. This clamp provides the holding power needed for larger posts, distributing force evenly to protect the anodized finish while you service cartridges and head assemblies.

Why You Need This
  • Oversize 34.9 mm shafts require higher holding force to loosen cartridge and head assemblies.
  • Direct clamping in an étau will instantly mark or ovalize the shaft.
  • This clamp provides full 360° contact to spread load evenly and avoid localized damage.
How to Use
  • Clean both the shaft and the clamp thoroughly with isopropyl alcohol.
  • Wrap the shaft in one single layer of paper towel or shop towel.
  • Install the clamp and close it fully before placing it in the étau.
  • Apply even clamping force, never crushing pressure.

⚠️ Warning

Contamination, misalignment, or partial contact can permanently scratch or deform the shaft. Oversize droppers transmit more torque than smaller posts. Cleanliness and correct positioning are critical.

Disclaimer
