## Description

ERROR: #N/A

Review: Fast Delivery & Quality Brand - I’m aware that I could’ve bought this item for less if I hadn’t been in such a hurry, but I needed a new lock fast. I got it from 365 Cycles because it included next-day delivery. Kryptonite’s mounting instructions are terrible, and the wrench is useless. Despite those two irritations, I’m still giving it five stars, mostly because of fast delivery and a quality brand. Also, the locking mechanism on the Evolution New-U works more smoothly than the Keeper.
Review: Solid Lock, Improved Mounting Kit - 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.
