Kryptonite's New York series sits at the top of the lock category for a reason — the Fahgettaboudit Chain 1415 and New York U-Lock are among the most cut-resistant locks available, built for high-theft urban environments where a lightweight cable lock is an invitation. The Evolution series brings similar protection at a lower price point, and the KryptoLok range covers everyday locking with solid security for lower-risk situations. Pairing a primary U-lock or chain with a secondary lock — the OTTO cinch lock concept — forces a thief to carry two different tools and spend twice the time, which is often enough to move on. OTTO's Hexband versions add a textured grip surface; the 18", 30", and 60" length options work for frames, wheels, or locking two bikes together.

For tracking, Muc-Off's Stealth Tubeless Tag Holder is the most discreet option — it fits an AirTag inside the valve stem cavity of a tubeless wheel, invisible from the outside. The Secure Tag Holder 2.0 mounts under the saddle or frame for a less hidden but more accessible placement. Lezyne offers AirTag-compatible options integrated into saddle bags and frame cages for riders who prefer tracking built into existing accessories rather than a standalone holder.
