PriceIn stock, ready to ship
This PRO clamp uses two bolts to spread the load, so it holds your post with only 4 Nm of torque. That makes it ideal for dropper posts, which can stick or bind if the frame clamp is over tightened. This is the 38.6 mm size.

The PRO 2-Bolt Seatpost Clamp is CNC machined from 6061 aluminium and closes with two bolts, spreading the clamping force evenly around the seat tube.
Because of that, it only needs 4 Nm of torque to hold firm. Low torque matters on dropper posts, where an over tightened clamp can squeeze the post and stop it moving smoothly.
This is the 38.6 mm size, which refers to the outside diameter of your frame's seat tube, not the seatpost. Measure the top of the seat tube before ordering.
