A solid disc lock is the first line of security defence, and the Oxford Beast definitely fits the bill. It’s a no-nonsense 1.3kg chunk of steel, with a cunning round design which is difficult for angle grinders and bolt cutters to get a hold of. Serious thieves might cut the disc, but even that’s tricky with the sheer size of the lock. It fits discs up to 8mm, has a 16mm hardened steel locking pin, and there’s a replacement key service from Oxford, too. Add a 22mm Beast Chain and it doubles up as a padlock to secure your bike to an anchor or solid point.
