Blackburn San Quentin Maximum Security U-Lock Bike Lock
The Blackburn San Quentin Maximum Security U-Lock bike lock is named after an American prison so is designed to give your bike high security whenever and wherever you leave it.
The bicycle lock uses a bump-proof dual bolt lock mechanism, making it virtually impossible to pick. The shackle of the lock is hexagonal 18mm alloy steel which will resist cutting and leverage attacks while an anti-scratch liner will protect the paint on your bike. The bike lock also inclues a mounting bracket.
