Axle Grabber.

Just in time for the weekend, I bought a pair of RockyMounts DriveShaft SD bike mounts. The Driveshaft SD was designed to bolt right into the UtiliTracks in the bed, and I particularly liked the fact that it can accept 9mm, 15mm RQ, and 20mm QR axles and has a built-in key lock. These things are pretty heavy and super solid; my mountain bike doesn’t budge or sway one bit while driving. I thought they were a little pricey at first, but they’ve been rock solid for over a year now.
