Kryptonite Kryptolok 12.7mm U-Lock with FlexFrame-U Bracket

The Kryptonite Kryptolok 12.7mm U-Lock with FlexFrame-U Bracket is a heavy and solid lock that provides great security for your bike. The lock is designed to deter potential thieves and ensure that they move on to another target. It features a useful long U shape that can easily secure your bike. One reviewer mentioned that the lock stopped working after using it only a few times, as it got stuck in the open position. However, this seems to be an isolated incident, as other customers have reported using the lock without any issues for extended periods of time. Another customer expressed their satisfaction with the lock, stating that it provides peace of mind when commuting to their college campus. They applied a drop of chain lube to prevent any potential binding issues and have experienced no problems in the last few months. The only downside they mentioned is that the U-shaped part of the lock could be more secure, as it tends to rattle around. On the other hand, there were some complaints about the misleading advertising of how to mount the lock. The dimensions provided do not match the pictures, and it may not fit on the majority of bikes. If your bike has internal cabling and a large frame, this lock may work for you. However, for most other bikes, it may be impossible to mount the lock to any part of the frame. Overall, the Kryptonite Kryptolok 12.7mm U-Lock with FlexFrame-U Bracket is a reliable lock that provides good security for your bike. However, potential buyers should be aware of its limitations in terms of mounting options.
