When it comes to bike locks, for years security has been synonymous with weight. Harder steel, thicker chains, every improvement came with the cost of heft. Until now (hopefully)! The dudes at Litelok invented a brand new composite material with a name that's almost as cool as what it does, Boaflexicore. It's light, flexible, and can withstand prolonged attacks to keep your bike safe! They're close to hitting their goal, so check 'em out at the link below and snag one for yourself! My favorite's the herringbone, what's yours?
