Lightweight Cable for Quick, Low-Risk Lock-Ups The Kryptonite KryptoFlex 525 is a compact, flexible cable that is best used as a secondary lock or for quick stops in low-risk areas. At 2.5 feet (76 cm) long with a 5 mm braided steel core, it is handy for looping through a front wheel, saddle rails, or helmet while your main lock secures the frame. The durable vinyl coating helps protect your bike’s finish and keeps the cable quieter in transit. It coils down small enough to live in a bag or basket, so it is always available when you need just a bit more reach or a simple deterrent for accessories. Small Things – Big Difference 5 mm braided steel cable offers basic security and strong flexibility. 76 cm (2.5') length is ideal for securing a wheel, saddle, or helmet alongside a primary lock. Vinyl coating helps protect your bike’s paint and keeps the cable from fraying other gear in a bag. Coils tightly for easy storage in a pannier, basket, or backpack. Works with most padlocks or U-lock shackles with enough internal space. Best used as a secondary or convenience lock in low-risk environments.
