⚡ At a Glance
- • Cut Resistance: High-performance alloy steel construction designed to resist cutting and leverage attacks
- • Best for: Commuters and urban cyclists who need dependable, everyday theft deterrence
- • Not ideal for: Lightweight touring riders who prioritise minimal weight above maximum security
D-style lock built from high-performance and alloy steel with an extra security cable. Zinc alloy lock cylinder includes two rust-resistant serpentine keys and a mounting bracket for on-bike storage.
Maximum cut resistance – thanks to high-performance steel shackle
Shackle constructed from 0.63in high-performance steel with parts also described as 0.56in alloy steel, and engineered to resist cutting, leverage and drilling attacks. Manufacturer states the mechanism can withstand up to 12 tons of hydraulic shear.
Exceptional physical resistance reduces the chance of opportunist theft and slows determined attackers, giving more time for detection or intervention.
Flexible locking options – with a 5 ft double-looped steel cable
Cable measures 5ft and is double-looped, with a thickness of 0.43in including the PVC covering, allowing multiple attachment points. PVC covering protects metal from weather and helps avoid damage to paintwork.
Frame, wheels, helmets and accessories can be secured to racks, poles or other bikes, making it easier to lock items that a D shackle alone cannot enclose.
Easy to carry and mount – with a sturdy bracket and protective cover
Lock measures 7.68in by 4.9in and comes with a mounting bracket compatible with seatposts between 26mm and 38mm, while a 0.10in silicone cover prevents scratches.
On-bike storage keeps security close at hand without needing a bulky bag, while the protective coating preserves the bicycle finish during transport.
