Exotek B64 HD Bi-Metal Titanium 67mm Puck Bones are an optional replacement titanium upgrade for the MIP Bi-Metal Bone Puck sets. Half the weight of steel (each bone weighs 2.3gr) and twice the strength of aluminum, these bones will help you achieve a lightweight drive line but increase the durability and reduce the wear and tear. Made of polished and laser etched Ti 6-4 titanium. 67mm long, when assembled -- same length as the 22 4.0 and B6 67mm cva/hub/axle sets (not for 65mm hub sets).

NOTE: Be sure to use a small amount of blue thread lock for hardware and black grease at pivot points when assembling.
