3T Difflock Caps for Oval Rails

Several of 3T's seatpost heads use their DifflLck cap system. Many of the posts come equipped with caps for 7x7mm round rails, and if you want to run a 7x9mm or 7x10mm oval rail saddle you simply need to swap out the DiffLock caps.

The item consists of the two 7x10mm compatible alloy caps with the two steel bolts you need to install them. Always use a torque wrench when installing your saddle. The torque spec is 7Nm.


  • 7x10mm clamp caps and bolts for 3T DiffLock saddle clamp mechanism
  • Aluminum caps with anodized black finish
  • Steel replacement bolts
  • Use a torque wrench- don't exceed 7Nm
