New York Lock Long Shackle

The long shackle model features a 10.25-inch shackle height, which provides significantly more clearance than the standard version. This extra length makes it easier to lock your frame and both wheels to larger or awkwardly shaped anchor points like thick poles or racks.

At 4.85 lbs, this is a substantial lock. While it provides top-tier security, you will definitely notice the weight in your backpack or mounted on your bike frame, so it is best suited for riders who prioritize maximum theft protection over a lightweight setup.

The 16mm diameter is quite thick, which is great for security but can be tight on some performance road bikes or frames with narrow clearance. It is designed to fit most standard city and commuter bikes, but it is worth measuring your frame's gaps if you have a specialized setup.

The sliding dust cover is very effective at keeping grit, road salt, and debris out of the disc-style cylinder. This is a crucial feature for longevity, as it prevents the locking mechanism from seizing up during wet or winter riding conditions.

Kryptonite offers an anti-theft protection program, but it requires you to register your lock on their website shortly after purchase. Be sure to read the specific terms and conditions on their site, as there are requirements regarding how the lock must be used to qualify for the coverage.
