TiGr Lock

We had high hopes for this unique 24-ounce titanium lock – the lightest and most portable we tested. We loved its scratch-defending PVC coating and simple top-tube bike mount. A pity, then, that our saw chewed through it in a mere 1:16 and our grinder in a minute. It was also the only lock to fall victim to the bolt cutters. [$200; tigrlock.com]
