Lock Loop lets you lock your bike together with two bolts to snap the spokes together. At only a pound and a half, it’s not much of a burden. It cozies up to your U-lock while in transit, so the package itself is fairly neat and streamlined. With your spokes inert, you’ve got an added layer of securityif you’re willing to put up with a few extra minutes of setup. The Lock Loop still requires you to carry around some extra bulk, but at just over a pound, it doesn’t feel like a heavy burden.”]
