High quality double bolt seatpost clamp from Nimbus to fit frames with an external diameter of 30.5mm. Having two bolts rather than one means that the seatpost is clamped much more firmly. This helps with seatpost twist when the unicycle is
dropped. Available in Black and Gold with Nimbus logo etched on front.
