This gave me an excuse to finally buy an adjustable chock, figuring that it would also be handy for other bikes around the shop. This would be an occasional tool, so I didn't feel the need to spring for something like the Condor, though I'd used one of those for years on a trailer and knew it was a tough piece of equipment. Instead I checked the reviews for Harbor Freight's version, broke out my 25% off coupon and grabbed one at my local store for only $50.
When I got it home, I emptied the box, bolted the front support/tie-down bar into place, adjusted the cradle position to fit the Victory's front tire and rolled it into place. Oops. Not so fast — when rolling a bike onto the chock, the entire piece just slides forward on the floor, which explains why the Condor video in the earlier link shows it blocked against a wall. I wanted it out in the open, so I simply sank two concrete anchors into a floor seam (won't show when the anchors are removed) and bolted 'er down. Very secure. After some experimentation with wheel sizes, I marked the frame adjustment holes for the different bikes' tires, front and rear, in the shop. This thing works as advertised and holds the bike very securely. For the Victory, I added some tie-downs for a little piece of mind, but later never felt the need for those. Be aware that the cradle isn't designed for really fat rear tires. I would recommend this product.
