Super cool Spiked Frame Plugs. CNC machined from billet aluminium, then polished. Held in place by a discrete M3 grubscrew which when positioned underneath, is invisible. Sold in pairs. This model is 25mm outside diameter, and 20mm spigot, so fits frames with a 20mm inside diameter, such as most Ducati's. Other sizes availble.
