High quality single bolt seatpost clamp from Nimbus Unicycles, to fit their new 34.9 frames. Even though this clamp is only a singlebolt, during tests it performed as good as a doublebolt clamp. This helps with seatpost twist when the unicycle is dropped. Available in Black or Silver.
This clamp will only fit frames with a external diameter of 34.9mm
