Bike-Guard Rocklock 1500 (Large)

Bike-Guard's Rocklock 1500 boasts a rugged 15mm-thick shackle, an equally tough offset crossbar and high-strength industrial ball bearings that withstand extreme loads and impacts. It results in a U-lock that resists attacks and has no gaps or weak areas. Plus, there's an anti-drill, anti-pull/pry reinforced lock cylinder, and the entire lock is plastic coated for weather resistance and to protect your bike's finish. This fine U-lock is backed with Bike-Guard's $2,000 anti-theft protection plan, too.
