    Solid Lock, Improved Mounting Kit
  

*by R***T on Reviewed in the United States on March 14, 2015*

Kryptonite is an industry standard for a reason. These locks are easy to use, and while heavy and a little bulky, give a good feeling of security.The longer shackle model of the lock can be a little bit harder to store on a bike however, especially if you use bottle cages.The mounting system for storage has been upgraded from previous lock models. Previous Kryptonite locks I have used included a plastic clip that was hard to attach and detach from the lock without breaking, not to mention a nightmare to install on the bike. With the new mounting kit, the plastic components are a little bit larger, but much more robust. The release mechanism feels less likely to snap, and the installation of the kit includes the use of a webbed strap and metal buckle (the bike is protected by a rubber insert) that firmly attach to the bike frame. Be cautious, however, that bike frames with non-round frame members can be a little hard to attach to.

    So far so good
  

*by K***E on Reviewed in the United States on September 1, 2024*

Needed security for bicycle at college.  So far working as bike has not been stolen.  Chose this lock as it is longer and that was needed to get through tire and frame on mountain bike.

    Solid lock

The key is difficult to turn and the lock bar doesn't go on and off very easily
