The Buffo 34 is Abuse's entry-level U-Lock and features a 12mm Special hardened steel shackle and supporting elements, double bolting shackle in the lock body and automatic keyhole cover that protects against dirt and corrosion. This makes it perfect for riders who do not need the weight and security of an urban-level lock but want the peace of mind that comes with using a hardened steel U-Lock instead of a cable.
