ABUS: The Ultimate 420 shares many attributes with its cousins the Super Ultimate 430 and the U-Mini 401 including the innovative through-body shackle and minimalist design. Made of high quality, temper hardened steel the Ultimate 420 has a slightly narrower inner width and lock body than the beefier Super Ultimate. The 14mm shackle double bolts into the lock body for robust protection against cutting and torsion attacks. The Ultimate features an innovative soft touch cover that protects your frame and, like all ABUS locks, feature industry-leading corrosion resistance. The red lock body gives it an understated appearance that doesn`t look out of place when fitted to a bike. Supplied with the proven, rattle-free USH universal frame bracket, this lock is full of features at a very sensible price point. It is insurance approved to Sold Secure Silver level and available in standard 230mm or long shackle 300mm versions. A great value lock & cable pack is also offered.
